addalmslot (add alarm card set)
Enables the MAJOR and MINOR alarm indicators on an Alarm Relay Card (ARC) or Alarm Relay Module (ARM) front card. It also configures the slot to provide external alarms from the Alarm Relay Interface (ARI) back card.
Use this command at each node equipped to provide external alarm indications to the customer alarm reporting system. The slot specified for the ARC or ARM may be any shelf slot, but is usually the slot farthest to the right.
Upon executing the command, the system places the alarm card set in the active state and displays the current alarm status.

addapsln/delapsln (add/delete SONET APS line)
Add a SONET APS (Automatic Protection Switching) line. The addapsln and delapsln command lets you add SONET APS (Automatic Protection Switching) for BXM OC-3 or OC-12 lines.
SONET APS is a standard that describes the switching of SONET lines from the active line to a standby line to provide hardware line redundancy. The SONET APS feature applies only to BXM OC-3 and OC-12 cards in this release.
When adding a new APS line pair, you must specify the desired APS protocol. The delapsln command deletes APS for the lines.
When the addapsln command executes, the switch software:
•Verifies that the slot.port arguments support APS
•Verifies that the appropriate back card is installed
•Verifies that the protection port is not already active
•If card redundancy is already configured for the two-slot case (APS 1+1), verifies that the primary card is the same type as the working line card.
Before the addapsln command has been executed, there is no working or protection line. The addapsln command defines which line is the working line and which line is the protection line. (For APS 1+1 Annex B, the active line is called the "primary section," and the standby line is called the "secondary section," which provides protection for the primary section.)
Feature Mismatching to Verify APS (Automatic Protection Switching) Support
The addapsln command, in addition to other configuration commands, performs mismatch verification on the BXM and UXM cards. For example, the addapsln command verifies whether the cards both have APS support configured. Refer to the BPX 8600 Series Installation and Configuration Manual.
Whenever you activate a feature by configuring it with CLI commands, switch software performs a verification to ensure that the hardware and firmware support the feature. For example, if you are attempting to add APS on a specific line (by using addapsln), and the BXM card does not support this feature, a warning message is displayed and the addition is not completed.
The Feature Mismatching capability does not mismatch cards unless the actual feature has been enabled on the card. This allows for a graceful card migration from an older release.

addapsln <slot.port1> < slot.port2> <protocol>
You must enter the slot.port pair and the protocol option. If you do not enter the protocol option, a menu lists the options.

addcon (add a data channel connection)
Establishes data channel connections between nodes in a network.
After you add a connection by using the addcon command, the node automatically routes the connection. The node where you execute addcon is the "owner" of the added connections. The concept of ownership is important because you must enter information about automatic rerouting and preferred routing at the node that owns the connection. See the cnfpref and cnfcos commands for more information on automatic rerouting. Before the node adds the connection, the proposed connection appears on the screen with a prompt for you to confirm the addition.
When applied to data connections, the addcon command adds a synchronous data connection to the network. You can add synchronous data connections to any node slot equipped with either an LDM or HDM in an IGX node. Before you add a connection, determine the desired data rate. To find the data rates that individual cards support, refer to the card descriptions in the Cisco IGX 8400 Series Reference manual.
When connecting sets of data channels, you do not have to specify the full channel set for the local end of the connection. You have to designate only the first channel in the range. For example, to add connects 27.1-4 at local node alpha to channels 9.1-4 at beta, you can enter:
addcon 27.1-4 beta 9.1
If Y-cable redundancy has been specified, you can add data connections at only primary card slots (not at the secondary card slots). See the addyred definition for more information. Standard Data Rates Table 3-1 through Table 3-9 follow, listing data rates. The following notations appear with some data rates:
In fast EIA signaling mode, an interleaved byte of EIA signaling information is associated with every byte of data in a packet. This format is appropriate for applications where EIA lead transitions must closely synchronize with user data. Fast EIA can apply to data rates up to 512 Kbps.
When FastPackets are built using the 7/8 coding format, each octet in the FastPacket payload consists of seven user data bits followed by a 1. This "bit-stuffing" allows these FastPackets to be safely carried on trunks that enforce ones density requirements by ensuring that each octet contain at least one 1 (such as IGX trunks configured for ZCS or AMI encoding). The user data may have any format and may contain any pattern, including all 0s. The single 1 inserted in the final bit position of each octet ensures that no more than seven consecutive 0s occur in a FastPacket. The 7/8 coding format is the safest mode to use when the data protocol is unknown and certain trunks in the network use ZCS or AMI.
When FastPackets are built using the 8/8 coding format, each octet in the FastPacket payload consists of eight user data bits. The 8/8 coding format is more efficient than the 7/8 format. However, the ones density requirement on trunks must be met by one of the following:
•Ensuring that the end-user equipment data protocol can never send more than seven consecutive 0s.
•Ensuring that the connection can never be carried on a trunk which uses ZCS ones density enforcement.
The vast majority of trunks today use intelligent ones density enforcement schemes, such as B8ZS, HDB3, B3ZS, or CMI. All such trunks can safely carry 8/8 data connections with no risk of data corruption. Data connections can be configured to NOT use ZCS trunks by specifying the optional "*Z" routing restriction.
When FastPackets are built using the 8/8I coding format, each octet in the FastPacket payload consists of eight inverted user data bits, i.e., each 0 is changed to a 1 and each 1 is changed to a 0. The bits are re-inverted at the far end of the connection. For such connections, the ones' density requirement on trunks must be met by one of the following:
•Ensuring that the end-user equipment data protocol can never send more than seven consecutive 1s.
•Ensuring that connection can never be carried on a trunk that uses ZCS ones density enforcement.
As with the 8/8 coding format, 8/8I connections can be safely carried on the vast majority of trunks today. However, the 8/8I format is primarily intended to provide the efficiency of 8/8 coding for any data which is HDLC or SDLC-based. HDLC/SDLC can never send more than six consecutive 1s, which, when inverted, automatically meets the ones density requirements of every possible trunk format.
If the data protocol requires an acknowledgment and is delay-sensitive, avoid routing the connection over a satellite line (*s for avoid). If 8/8 or 8/8I coding is the selected format, avoid trunks with zero code suppression (*z for avoid) because the zero code suppression could corrupt the last bit in the byte.

Example
For CDP to CDP or CVM to CVM, add a 256 Kbps (4x64) data connection from a CDP (or CVM) at node alpha to the CDP (or CVM) at node beta. The syntax for this example requires that the start and end channel are entered for both ends of the connection and that the data rate is specified to be the same at both ends.
addcon 5.4-7 beta 6.1-4 4x64
The channel numbers can be different on each end if they are contiguous.
addcon (add channel voice connections)
Establishes the channel connections between nodes in the network. You can add voice connections to any slot that has a CDP, UVM, or CVM. Before you add a connection, determine its compression type.
If you plan for a port on a UVM to carry more than 16 channels with LDCELP or the G.729 version of CACELP, you must have a second, connected UVM and configure the resultant pair of UVMs for passthrough operation. If you attempt to add more than 16 LDCELP or G.729 channels, the system reports any excess connections as being failed connections after addcon execution finishes. Furthermore, if you execute dspcon, the status display for the excess connections shows "ConnRJ" (connection rejected). Refer to the cnflnpass description in this chapter and the UVM description in the Cisco IGX Reference for a description of passthrough.
After you have established passthrough for a pair of UVM card sets, the system does not allow duplication of channel numbers when you add connections. For example, if you add 7.1.1-16, the node does not allow you to add 8.1.1-8 if you have linked the UVMs by using cnflnpass. Instead, you would add 8.1.17-24.
A UVM with Model B or higher firmware supports CAS switching. Before you can add connections in a network with CAS switching, you must configure the UVM for this feature by using the cnfcassw command. Note that, for CAS switching, you use addcon to add the signaling channels at the near and far end in the format slot.port.24 on a T1 line and slot.port.16 on an E1 line. Also, the connection type for these signaling channels is "t." If you specify D-channel compression, the connection type is "td." See the description of cnfcassw in the "Setting Up Lines" chapter or, for a more detailed description, the manual titled Cisco VNS (Voice Network Switching) Installation and Operation.
When adding a range of channels, you do not have to specify the full channel set at the near-end. You may specify only the first channel in the set. For example, to connect channels 13.1-10 at alpha to channels 12.5-14 at beta, you could enter "addcon 13.1-10 beta 12.5." In this example, channel 13.1 is connected to channel 12.5, and channel 13.2 is connected to channel 12.6, and so on.
Connections are added with a default class of service (CoS). The value of CoS is the number of seconds that the node waits before it reroutes the connection after a failure. The CoS applies to various types of connections other than voice.
Table 3-10 and Table 3-11 describe what you enter for the type parameter for each rate and compression variable.
The difference between a PCM (p) connection and a transparent (t) or transparent D-compression (td) connection is that the D4 frame signaling bits are identified and processed as signaling information with PCM connections. PCM connections permit gain adjustment to be applied to the connection. Transparent connections treat all bits, including signaling bits, as data bits and disables any gain adjustment conversion that you may have specified.
The number in the type field indicates the ADPCM rates in Kbps. The "z" suffix indicates that 00 code level is used. Type a16 or c16 uses only 01, 10, and 11 binary codes to avoid long strings of zeros. Type a16z and c16z connections use the 00 code and are automatically configured to avoid ZCS lines (*Z).
Syntax
addcon <local channel> <remote node> <remote channel> <type> [avoid]
Parameters
Parameter Descriptionlocal channel
Specifies the local channel or set of channels to add. Right-angle brackets indicate a range of channels. Channel specification on a UVM has one more parameter than the specification on a CDP or CVM:
For a CDP or CVM, the format for channel specification is slot.chan[-chan].
For a UVM, the format for channel specification is slot.line.chan[-chan].
Refer to the Cisco IGX Reference for a description of the UVM's lines. Note that, if you are using CAS switching with Model B firmware, line must be 1.
remote node
Specifies the name of the node at the other end of the connection. For a DAX connection (where channels on a node are connected to channels on the same node), use the local node name.
remote channel
Specifies the remote channel or set of channels to connect. Brackets indicate that a range of channels can be specified. Channel specification on a UVM has one more parameter than the specification on a CDP or CVM.
For a CDP or CVM, the format for channel specification is slot.chan[-chan].
For UVM, the format for channel specification is slot.line.chan[-chan].
type
Specifies the voice connection type. Refer to Table 3-9 or Table 3-10 for voice connection types and compression.
For connections to an access device such as the Cisco 3810, type can be one of the following: 24 Kbps or 32 Kbps ADPCM, LDCELP, or CACELP.
avoid
Specifies the type of trunk for the connection to avoid.
Optional
Default: no avoidance.
The choices are:
•s - avoid satellite trunks.
•t - avoid terrestrial trunks.
•z - avoid trunks using zero code suppression techniques that modify any bit position to prevent long strings of zeros.

addcon (add a Frame Relay connection)
After you add a connection, the system automatically routes the connection. The node on which you execute addcon is the owner of the connection. The concept of ownership is important because you must specify automatic rerouting and preferred routing information at the node that owns the connection. See the cnfpref and cnfcos descriptions for information on automatic rerouting. Before it actually adds the connection, the system displays the parameters you have specified and prompts you to confirm them.
Note For cards with Y-cable redundancy specified, you can add connections to only primary cards.
Each Frame Relay connection (and associated user device) has a local identification in the form of a unique DLCI. The total range for DLCIs is 1-1023. Typically, DLCIs 16-1007 are available for local and remote channels. According to ANSI standards, DLCIs 1-15 and 1008-1022 are reserved. DLCI 1023 is reserved for LMI signaling.
Only a UFM could come close to using all DLCIs. The maximum number of connections on a UFM is 1000. The maximum number of Frame Relay connections on an FRC or FRM is 252.
If a user device can automatically determine the network configuration by using the LMI, you do not need to specify the DLCIs in the network to the device. If a device cannot interrogate the network to determine the DLCIs in the network, you must specify the network DLCIs to the user device.
As the following sections describe, you can generally differentiate Frame Relay connections as normal, bundled, grouped, and frame forwarding. In particular, a Frame Relay connection can also terminate at a Frame Relay endpoint or an ATM endpoint if the endpoints have firmware to support this arrangement. A connection that terminates at Frame Relay and ATM endpoints uses service interworking (SIW).
Service Interworking
Frame Relay connections that terminate at ATM endpoints require service interworking (SIW) support. At the Frame Relay end, service interworking is one of the optional parameters. The line cards on which you can add service interworking connections are:
•the UFM on an IGX node
•ASI on a BPX node
•FRSM in an MGX 8220 shelf.
The Frame Relay endpoint has an identifier in the format slot.port.DLCI.
For SIW connections, the ATM endpoint identifier has the format slot.port.vpi.VCI.
Note You cannot group or bundle SIW connections with non-SIW connections.
Adding connections to a virtual port for a BXM card does not require the virtual port number. The slot, port, and VPI map to the supporting virtual port. In addition, Vc QDepth is configurable for all connection types.
Bundled Connections
A normal connection is a single PVC. A Frame Relay PVC can terminate at either a Frame Relay endpoint or an ATM endpoint.
Connection bundling creates a full mesh of connections between two groups of Frame Relay ports by executing addcon command only once. When you add a bundle between two groups of ports, you create a connection between each port of one group of ports and each port of the other group of ports. Each group of Frame Relay ports can include up to four ports. Consequently, the maximum number of connections in a bundle is 16 (resulting from a full mesh of connections between two groups of four ports each).
Note that a Port Concentrator Shelf does not support bundling.
Characteristics of connection bundling are:
•The number of ports used at each end of the bundle does not have to be the same.
•All of the ports used in a group must be on the same card.
•Only the FRP Model D and the FRM Model D support connection bundles. The UFM does not support connection bundling.
•All of the ports used for a bundle must be contiguous. For example, a bundle on a card may not consist of only ports 1, 3, and 4.
•The syntax for specifying a group of ports for a connection bundle is slot.port[xport].
When you create a connection bundle with addcon, you do not explicitly specify the required DLCI at each endpoint of each connection. Instead, the DLCIs are automatically assigned using global addressing with the Port IDs, which have been previously assigned to the ports. Consequently, you must first assign a Port ID (other than 0) to every port to which you plan to assign a connection bundle. Use cnfport to assign a Port ID or dspport to see an existing Port ID.
For example, the command
addcon 6.1x3 alpha 7.2x3 1
defines a single connection bundle between a local group of 3 ports (ports 1, 2, and 3 on card 6) and a remote group of 2 ports (ports 2 and 3 on card 7). The resulting connection bundle consists of these six connections:
local node slot 6.port 1 to node alpha slot 7.port 2
local node slot 6.port 1 to node alpha slot 7.port 3
local node slot 6.port 2 to node alpha slot 7.port 2
local node slot 6.port 2 to node alpha slot 7.port 3
local node slot 6.port 3 to node alpha slot 7.port 2
local node slot 6.port 3 to node alpha slot 7.port 3
Each connection in the bundle is assigned the parameters of the same Frame Relay class (class 1, in the example above). Notice that no DLCIs were specified for the six connections. The DLCIs are automatically assigned using the Port IDs of the ports.
As an example, assume that the following Port IDs had been previously assigned for the five ports.
port 6.1Port ID = 22
port 6.1Port ID = 534
port 6.3Port ID = 487
port 7.2Port ID = 92
port 7.3Port ID = 796
As a result of the addcon command, the six connections that you create are automatically assigned DLCIs using global addressing as follows.
6.1.92 - 7.2.22
6.1.796 - 7.3.22
6.2.92 - 7.2.534
6.2.796 - 7.3.534
6.3.92 - 7.2.487
6.3.796 - 7.3.487
The dspcons display shows the entire bundle as a single item. Therefore, you cannot see the automatically assigned DLCIs on the dspcons screen. (The automatically assigned DLCIs in the preceding list appear in italics.) To see the DLCIs, use dspcon, as in the following example:
dspcon 6.1x3 alpha 7.2x3
The preceding shows one screen for the whole bundle then an additional screen for each connection in the bundle. The assigned DLCIs appear in these individual connection display screens.
Note If you request help for addcon at the command line prompt, the Help line shows type as a parameter. However, when you are using addcon for a Frame Relay connection, the type shown in the help display is actually the Frame Relay class shown on the preceding syntax line As stated, you can optionally override any or all of the bandwidth parameters and ForeSight-enable in the Frame Relay class by typing the parameters that appear as frp_bw and avoid in the Help display.
Note also that you do not enter the coding parameter shown on the Help line.Frame Forwarding Connections
A non-Frame Relay data connection (such as HDLC or SDLC) that is routed through Frame Relay cards can bypass a router or take advantage of DFM at higher data rates. The format slot.port.* identifies a frame forwarding connection. For example:
addcon 11.2.* alpha 12.3.* 2
The "*" indicates to the node that a DLCI is meaningless.
Maximum Connections Per Port with Signaling Protocols
For any Frame Relay card set that has a maximum frame length of 4510 bytes, the use and type of signaling protocol you may have (optionally) specified with the cnfport command results in a limit on the possible number of connections per physical or logical port. The maximum number of connections per port for each protocol is:
•For Annex A: 899
•For Annex D: 899
•For StrataLMI: 562
The addcon command does not prevent you from adding more than the maximum number connections on a port. If the number of connections is exceeded, the particular LMI does not work on the port, the full status messages that result are discarded, and LMI timeouts occur on the port. A port failure results and subsequently leads to A-bit failures in segments of the connection path.

addcon (add an ATM connection)
Establishes an ATM connection between the current node another node in the network. ATM connections are added to UNI or NNI ports on ASI or BXM interface cards in a BPX node and UXM or URM interface cards in an IGX node. Before a connection is added, you are prompted to confirm the connection addition. After addcon executes, the system software automatically routes the connection.
The addcon command for ATM adds any one of the following types of ATM connections:
•Constant Bit Rate (CBR)
•Variable Bit Rate (VBR)—rt-VBR and nrt-VBR
•Frame Relay-to-ATM interworking connection (ATFR)
•Frame Relay-to-ATM interworking with ForeSight (ATFST) connection
•Available Bit Rate according to ATM Forum standards (ABRSTD)
•Available Bit Rate with ForeSight (ABRFST)
•Frame Relay-to-ATM transparent Service Interworking (ATFT)
•Frame Relay-to-ATM transparent Service Interworking with Foresight (ATFTFST)
•Frame Relay-to-ATM translational Service Interworking (ATFX)
•Frame Relay-to-ATM translational Service Interworking with Foresight (ATFXFST)
•Unspecified Bit Rate (UBR)
Frame Relay-to-ATM Interworking enables Frame Relay traffic to be connected across high-speed ATM trunks using ATM standard Network and Service Interworking. Two types of Frame Relay-to-ATM interworking are supported, Network Interworking and Service Interworking.
You can add connections to a virtual port on a BXM card. When adding a connection to a virtual port, the virtual port number is not required. The slot, port, and VPI will map to the supporting virtual port. In addition, Vc QDepth is configurable for all connection types.
The node on which addcon executes is the "owner" of the connection. Automatic rerouting and preferred routing information is entered on the node that owns the connection. See the cnfpref and cnfcos descriptions for details on automatic rerouting.
If addcon is attempted on a port with F4-F5 mapping enabled, and there are no channels left for F4-F5 mapping, the following message is displayed: "No channel left for F4-F5 mapping on this portgroup." If channel unavailability occurs at the remote end, the following message is displayed: "No channel left for F4-F5 mapping on this portgroup at the remote end."
For detailed descriptions of the connection types, traffic classes, policing, and ATM-related topics, refer to the Cisco BPX 8600 Series Installation and Configuration guide or the ATM Forum specifications.
Syntax
addcon <local_channel> <remote_node> <remote_channel> [connection_class] [individual parameters]
Parameters
The addcon parameter prompts depend on the connection type. The following two tables define the parameters and list the defaults and ranges for each parameter.
The notation (0), (1), or (0+1) appears for some parameters. This refers to the state of the Cell Loss Priority (CLP) bit. The usage of the CLP bit is in the traffic policing schemes: (0+1) means cells with CLP=0 or 1; (0) means cells with CLP=0; (1) means cells with CLP=1. The CLP bit is used in different contexts. For example, CDVT (0+1) refers to Cell Delay Variation Tolerance (CDVT) for cells with CLP=0 or 1.
Parameter Descriptionlocal channel
Specifies the local slot, port, virtual path identifier (VPI), and virtual connection identifier (VCI) for the connection. The format is slot.port.vpi.vci.
You do not need to specify the virtual port (if one has been activated for this channel). The slot, port, and VPI will automatically map to the correct virtual port.
The VPI range for a UNI connection is 1-255. The VPI range for an NNI connection is 1-4095.
When adding an MGX 8850 interface shelf with a UNI interface to a BPX routing node, the VPI range is 1-255. The VCI range is 1-65535.
When adding an MGX 8850 interface shelf with an NNI interface to a BPX routing node, the VPI range is 1-255. The VCI range is 1-65535.
When adding an SES (Service Expansion Shelf) to an IGX 8400 routing node, for VCC addressing, the VPI range is 1-255. The VCI range is 1-65535.
For VPC addressing, when adding an SES interface shelf to an IGX 8400 routing hub with a UNI interface, the VPI range is 1-255. The VCI range is 1-65535.
For VPC addressing, when adding an SES shelf to an IGX 8400 routing with an NNI interface, the VPI range is 1-4095. The VCI range is 1-65535.
Note that when adding an SES to an IGX 8400 routing node, the VPI/VCI configured on the IGX 8400 routing hub should match the VPI/VCI configured on the SES interface shelf endpoint address.
When adding a VP tunnelling DAX connection to an IGX UXM card, either end of the connection can be the VPI or VCI side. This connection type can be any of the ATM connection types supported by UXM virtual trunks, for example, ABR, CBR, UBR, and VBR.
The VCI range is 1-65535. The VCI can be an asterisk (*) to indicate the connection is a virtual path connection (so the VCI has no meaning within the network).
Note The VCI cannot be less than 33, if F4-F5 mapping is enabled on the port.
remote node name
Specifies the name of the node at the other (or remote) end of the connection.
remote channel
Specifies the remote node's slot, port, VPI, and VCI for this connection. The format is slot.port.vpi.vci. The VPI and VCI ranges are:
The VPI range for a UNI connection is 1-255. The VPI range for an NNI connection is 1-4095.
The range for a VCI is 1-65535. The VCI can be an asterisk (*) to indicate the connection is a virtual path (the VCI does not provide a distinction within the network).
Note The VCI cannot be less than 33, if F4-F5 mapping is enabled on the port.
You do not need to specify the virtual port (if one has been activated for this channel). The slot, port, and VPI will automatically map to the correct virtual port.
connection class/
traffic typeSpecifies one of the following traffic types—VBR (rt-VBR or nrt-VBR), UBR, CBR, ATFST, ATFR, ABRSTD, ABRFST, ATFT, ATFX, ATFTFST, or ATFXFST; or connection classes—for example, for rt-VBR, connection class 3 for a new node running Release 9.2.20.
The subsequent displayed parameters depend on the connection type you choose. To see the parameters associated with each connection type, refer to the appropriate flow diagrams in the Cisco BPX 8600 Series Installation and Configuration guide.
Instead of entering a class of service, you can choose a class number. The class number represents a preconfigured template for a connection type. The class serves as an alternative to specifying each parameter for a connection type. For example, class 4 for nrt-VBR, and class 3 for rt-VBR. To specify a connection class, enter a digit in the range 1-10. To see the parameter values for a class, use the dspcls/dspatmcls commands. To customize any class template, use the cnfcls/cnfatmcls commands.
Note For a new node running 9.2.20 or later, the rt-VBR connection class number is 3. An upgraded node will retain existing connection classes and will not have the rt-VBR connection class 3. However, you can configure the connection classes to whatever service and parameters you want by using the cnfcls/cnfatmcls commands.
Note For VP tunnelling DAX connections, a VP tunnelling connection type is represented by CBRVP, ABRSTVP, ABRFSTVP, and so on. The letters VP are appended to the connection class or connection type, to indicate that it is a VP tunnelling connection. This connection type must be the same as the VCC connection type provisioned within the public ATM cloud.
PCR
Peak Cell Rate: the cell rate that the source cannot exceed.
%Util
Specifies the percentage of bandwidth utilization.
MCR
Minimum Cell Rate: the committed, minimum cell rate for a connection in a network.
CDVT
Cell Delay Variation Tolerance: controls policing tolerance for cells which are early or late relative to the PCR.
FBTC (AAL5 Frame-based Traffic Control)
Enables the possibility of discarding the whole frame, not just one non-compliant cell. This is used to set the Early Packet Discard bit at every node along a connection.
With the ASI, FBTC means packet discard on both policing and queueing. With the BXM, FBTC means packet discard on queueing only.
VSVD
Virtual Source Virtual Destination.
Flow Control External Segments
Enables Cisco WAN switches to perform flow control on external segments (on the CPE, for example) in addition to the Cisco WAN Switching segments.
SCR
Sustainable Cell Rate: the long-term limit on the rate that a connection can sustain.
MBS
Maximum Burst Size: the maximum number of cells that can burst at the PCR and still be compliant. MBS is used to determine the Burst Tolerance (BT), which controls the time period over which the SCR is policed.
Policing
Selects the type of policing to be applied to this connection. Possible values are 1-5. See Table 3-15 for details about each of the five policing modes.
VC QDepth
The depth of the queue VC QDepth. As of Release 9.3, VC QDepth can be configured for all connections, not just ABR connections.
CLP Hi
Cell Loss Priority Hi threshold (% of VC QDepth). When the high threshold is exceeded, the node discards cells with CLP=1 until the number of cells in the queue drops below the level specified by CLP Lo/EPD. As of Release 9.3, CLP Hi can now be configured for all connections, not just ABR connections.
CLP Lo/EPD
Cell Loss Priority Low threshold (% of VC QDepth)/Early Packet Discard. When the number of cells in the queue drops below the level specified by CLP Lo/EPD, the node stops discarding cells with CLP=1.
If the card is a BXM and AAL5 FBTC=yes, the percent of VC QMax equals the value of EPD. Frame-based Traffic Control (FBTC) is FGCRA for AAL5.
For an ASI card, the percent of VC QMax is CLP Lo regardless of the FBTC setting.
As of Release 9.3, CLP Lo/EPD can now be configured for all connections, not just ABR connections.
EFCI
Explicit Forward Congestion Indication threshold (% of VC QDepth).
ICR
Initial Cell Rate: the rate at which a source initially transmits after an idle period.
IBS
Initial Burst Size: the maximum burst size a source can initially transmit after an idle period. IBS applies only to BXM cards.
ADTF
The Allowed-Cell-Rate Decrease Factor.
Time permitted between sending RM cells before the rate is decreased to ICR. (In previous software releases, ADTF was ICR TO—Initial Cell Rate Time Out.)
Trm
An upper bound on the time between forward RM-cells for an active source: an RM cell must be sent at least every Trm milliseconds. (In previous software releases, Trm was Min. Adjust.)
RIF
Rate Increase Factor: controls the amount by which the cell transmission rate may increase upon receipt of an RM cell. (In previous software releases, RIF was Rate Up.)
RDF
Rate Decrease Factor: controls the amount decrease in cell transmission rate when an RM cell arrives. (In previous software releases, RDF was Rate Down.)
Nrm
Nrm.
Maximum number of cells a source may send for each forward RM cell: an RM cell must be sent for every Nrm-1 data cells.
FRTT
Fixed Round Trip Time: the sum of the fixed and propagation delays from the source to a destination and back.
TBE
Transient Buffer Exposure
The negotiated number of cells that the network would like to limit the source to sending during start-up periods, before the first RM-cell returns.

PCR Values and Traffic Policing
The following three tables provide additional information on PCR values and traffic policing. Table 3-14 defines the minimum PCR values with policing for each card type. Table 3-15 provides traffic policing definitions for each connection type.
addctrlr (add a VSI controller to an IGX node)
Add VSI controller to a UXM line interface. Use the addctrlr command to add an VSI controller to UXM line interface on an IGX node. You can connect a VSI controller to an IGX node by physically connecting a cable from the controller to the UXM line interface.
You cannot connect a VSI controller to these interfaces:
•trunk
•virtual trunk
•feeder trunk
•IMA ports
The maximum number of controllers that can be added to an IGX is three, although the valid controller ID range is 1 to 16.

addctrlr (add VSI capabilities to an AAL5 feeder interface (BPX))
Adds VSI capabilities to a trunk interface to which a feeder of type AAL5 is attached. Use the addctrlr command to connect a Private Network-to-Network Interface (PNNI) controller. PNNI controller software resides on the Service Expansion Shelf (SES) hardware.
To add a PNNI controller to a BPX node:
Step 1 Run the command addshelf with shelf type set to X to add an AAL5 feeder. This ensures that Annex G protocol runs between the BPX and the SES.
Step 2 Run the addctrlr command to set up the VSI control channels from the PNNI SES controller to the VSI slave processes running on the BXM cards to ensure full VSI functionality for the PNNI controller. Execute the addctrlr command on an existing AAL5 interface shelf.
Note that you can add a PNNI controller to a trunk interface only if the interface already has an active VSI partition corresponding to the partition that is controlled by the PNNI controller. For example, if a PNNI controller controlling partition 1 were added to a trunk interface 12.1. Then it would be necessary that a VSI partition corresponding to partition 1 be active on the interface 12.1. Otherwise the addctrlr command would fail.
When adding VSI controller capabilities to an AAL5 interface shelf (or feeder), the switch software prompts you for the specifics of the VSI controller:
•controller ID of the PNNI controller
•partition ID of the VSI partitions controlled by the PNNI controller
•VPI used for the VSI control channels set up by the PNNI controller
•start_VCI value for the VSI control channels set up by the PNNI controller
The PNNI controller controls VSI partitions on those BXM cards that support VSI capability. Hence a separate VSI control channel must be set up from the PNNI control to each BXM card that supports VSI.
Example: You specify a VPI value of 0 and start_VCI value of 40 for the VSI control channels. Then the control channel corresponding to any BXM card on slot 1 would use VPI, start_VCI values <0, 40>. The VSI control channels to other slots would use the VPI, start_VCI values of <0, 40+slot-1>, where "slot" corresponds to the slot number of the BXM card.
Caution For feeder trunk interfaces, the addctrlr command will fail if the Automatic Routing Management connections terminating on the feeder interface use the same VPI start_VCI as those specified for the VSI control channels. You must delete the connections before proceeding if connections with VPI and start_VCI in the range exist in the range you specified.
The addition of a controller to a node will fail if there are not enough channels available to set up the control VCs in one or more of the BXM slaves.

addextlp (add external loop)
Places an external device in loopback mode. The addextlp command applies to existing connections on an SDP, HDM, LDP, or LDM. A near loopback causes the NEAR EIA template to be applied. A far loopback causes the FAR EIA template to be applied to the data port. The loopback remains in place until removed by the dellp command.
The dspcons command shows which connections are in loopback mode. Specifying an "n" after the channel indicates a near loopback, and an "f" indicates a far loopback. Because addextlp takes the specified connections out of service, use it only when a service disruption is tolerable.

addjob (add a job)
Creates a job or command script. When you create a new job by using addjob, your privilege level becomes the privilege level of the job itself. When adding commands to the job, you cannot add a command that requires a privilege higher than your privilege level. Furthermore, you must have a privilege level at least as high as the job to run the job (with runjob, for example).
The system does not check the validity of the command with respect to the current state of the network or for relationships to other commands in the job. To ensure that it works as expected, try running the job with runjob.
Syntax

The job is scheduled to run on August 17, at 2:20:30 PM and every day thereafter at the same time. The command in the job is prtlog. If this command fails when the job runs, it tries twice again and aborts if unsuccessful.
The "Enter Cmd" prompt at the bottom of the screen indicates you can enter the next command for the job. To exit addjob, press Return without entering a command.
addjobtrig (add job trigger)
Configures a job to run if a failure or repair occurs on a trunk (narrowband or broadband), a line (voice, data, Frame Relay, ATM, narrowband, broadband), or a T3 (DS3). You can also use addjobtrig to allocate or release bandwidth from other connections. This bandwidth decision depends on whether the EIA lead status is "up" or "down." For example, a job can be triggered to run if the RTS lead of an HDM/LDM port changes state. If the FRM you are using is an FRM-T1 or E1, it qualifies as a line and can be used as a job trigger.
A line failure is any alarm condition that takes the trunk or line out of service. Such a condition is always a major alarm. However, not all major alarms cause the trunk or line to be considered failed. Those that are considered failed are the ones that appear on the dsptrks or dsplns screens with a color associated with it, such as "Major—Local All Ones" or "Major—Remove Packet Out of Frame (Yel)". Specifically excluded are all the statistical alarms, some of which may be major.
A line repair is the opposite of a line failure. A repair of a line occurs when the alarms on the line are removed.
The lead type on HDM/LDM is based on the configuration from cnfleadmon. The display shows: "Front Card Supports Lead State Trap".

addlnloclp (add local loopback to line)
Establishes a local-remote loopback on a trunk or port card in a BPX. Applicable cards are the ASI, BNI, BME, and BXM.
While a line loop is present, software suspends the card self-test and the line diagnostic test that normally run when a line goes into alarm. Suspending these tests prevents background test loops from interfering with the user-specified loop.
Line loops are set for a line on the local node, so you cannot specify a remote node, and no network messaging is supported for setting a line loop of any type on a remote node.
Line loop status is displayed on the dsplns screen for an ASI, BME, or a BXM in port mode and the dsptrks screen for a BNI, BME, or a BXM in trunk mode. Line loop status is not displayed for connections (dspcons) affected by a line loop. Instead, a warning is printed if the line has connection traffic travelling on it, and an event is logged when a line loop is set or cleared. A line loop on a trunk generates Comm Fail, causing connections to fail and be rerouted.
For both of the dsplns and dsptrks screens, the "[" character appears before the back card type in the "Type" column to indicate that the line local loopback is active.
The line loop state is not saved in BRAM or on a rebuild but is preserved on a switchover. After a rebuild, a line's loop state is cleared.
Exercise caution when you set up loops on a BNI, BME, or BXM trunk because looping an added BNI/BXM/BME trunk causes Comm Failure and connection rerouting. BNI/BXM/BME addlnlocrmtlp is not supported because of a lack of useful purpose, and Cisco recommends that you use addlnloclp only when the trunk is upped but not added. On the other hand, the system does not prevent you from looping an added BNI/BXM/BME trunk port.

In this release, you can use the addloclp and addlocrmtlp commands to enable a two-segment connection at the hub node port endpoint in a network of IGX hubs and MGX 8800 interface shelves. The addloclp and addlocrmtlp commands are blocked at the interface shelf trunk endpoint. The addrmtlp command is not supported at either endpoint of the connection. You can use the dellp command to remove the local (or local remote) loopbacks that have been added; however, you cannot use the dellp command at the trunk endpoint of the connection—it will be blocked. Loops of any kind are not supported for the middle segment of a three-segment connection.

addloclp (add local loopback to connections on a port)
Places these types of channels in local loopback mode:
•Voice
•Data
•Frame Relay port
•Frame Relay connection
•ATM connection
•Access device port
For voice connections, addloclp creates a signal path from a channel or group of channels on an incoming line then back out to the line. External test equipment can test the integrity of the path at the T1 DS0 level. Figure 3-3 shows a local loopback on a voice channel.
Figure 3-3 Local Loopback on a Voice Channel
For data connections, addloclp creates a signal path from the incoming data port or set of ports back to these same port(s) through the local CDP/CVM, SDP/HDM, or LDP/LDM. External test equipment can then test the integrity of the path. Figure 3-4 illustrates a local loopback on a data connection.
Figure 3-4 Local Loopback on a Data Connection
A local loopback can simultaneously exist at both ends of a connection. However, a local loopback and a remote loopback cannot co-exist on a connection. (See the addrmtlp description for more information.)
Before executing a loopback, the IGX node performs signal and code conditioning to remove the connection from service. The loopback remains in place until removed by the dellp command. Only existing connections can be looped back.
Use the dspcons command to see which connections are looped back. A flashing right parenthesis ")" or left parenthesis "("is used in the connections display to indicate a loopback. The direction and location of the parenthesis depends on whether the loopback is local or remote and which end of the connection was used to establish the loopback.
A local loopback initiated from the local end of the connection looks like this in the connections display:
A local loopback initiated from the remote end of the connection looks like this:
In Frame Relay connection loopback mode (DLCI included in command), all packets from the far-end of the connection are dropped. The far-end system software is informed of the loopback. In port loopback mode (port specified without a DLCI), all packets for this port are dropped and each opposite end is informed of the loopback mode.
Use the format slot.port in port mode to loop just the port. The data is looped directly in the FRI back card, so no data reaches the muxbus or cellbus. Use the format slot.port.DLCI in connection (channel) mode to loop a specific channel. Note that this can affect up to 252 connections (channels) in port loopback mode.
Because the addloclp command causes the connection(s) to be removed from service, you should use loopbacks only when a service disruption can be tolerated. You establish remote loopbacks with the addrmtlp command. You remove local and remote loopbacks with the dellp command. You can also initiate loopbacks for data channels by pressing a button on the front of the associated data card.
Frame Relay Local Loops with Port Concentrator
When a Frame Relay port or connection is located on a Port Concentrator instead of directly on an FRP or FRM card, the data test path is different. When just the <port> parameter is used, incoming data is looped back out on the Port Concentrator port, as shown in Figure 3-5.
Figure 3-5 Local Loop on Port Concentrator
This loop disrupts all Frame Relay connections on the port that is under test.
When you specify a connection with <port.dlci> parameters, the connection is looped back at the FRM-2 or FRP-2 interface with the IGX card bus, as shown in Figure 3-6.
Figure 3-6 Local Loop on FRM-2 or FRP-2
As shown, this test verifies the operation of all components from the Port Concentrator to the IGX interface with the FRP-2 or FRM-2 card.
This tests interrupts only the specified connection on the Port Concentrator port.
In this release, the addloclp and addlocrmtlp commands support the two-segment connection at the hub node port endpoint in a network of IGX hubs and SES interface shelves. The addloclp and addlocrmtlp commands are blocked at the interface shelf trunk endpoint. The addrmtlp command is not supported at either endpoint of the connection. You can use the dellp command to remove the local (or local remote) loopbacks that have been added; however, you cannot use the dellp command at the trunk endpoint of the connection—it will be blocked. Loops of any kind are not supported for the middle segment of a three-segment connection.

addlocrmtlp (add local-remote loopback in a tiered network)
Adds support of a local-remote loopback for testing multisegment connections in a tiered network. The effect is to instruct the remote node to set up a remote loopback.
You must execute the addlocrmtlp command before using tstcon and tstdelay for multisegment connections. For interface shelves, you can execute addlocrmtlp on either the interface shelf (after you telnet to it).
After testing is complete, remove the local-remote loop by executing dellp. A parenthesis on the screen shows the loop's endpoint.
The addloclp and addlocrmtlp commands support a two-segment connection at the hub node port endpoint in a network of IGX hubs and SES interface shelves.

addport (add ATM or Frame Relay port)
This command is required to add ports to the IGX and BPX. Use addport to:
•add an ATM port to the BPX (for example, ASI, BXM, physical, or virtual port).
•add the internal ATM port to the embedded UXM in the Universal Router Module (URM) (introduced in Release 9.3.20 on the IGX 8400).
•add a Frame Relay port to the IGX on a channelized FRP, FRM, or UFM card set. Only T1 or E1 lines carry channelized Frame Relay traffic, so the addport command does not apply to a Port Concentrator Shelf or front cards with a V.35, X.21, or HSSI interface.
•Only T1 or E1 lines carry channelized Frame Relay traffic, so the addport command does not apply to a Port Concentrator Shelf or front cards with a V.35, X.21, or HSSI interface.
•The addport command adds a logical Frame Relay port by using the slot number of the FRM and the DS0/timeslots that make up the logical port. On a UFM, the logical ports span the whole range of physical lines: you associate the logical ports to the lines as needed, then include the DS0s as the last field of the argument.
Note If you attempt to add a Frame Relay port on the UFM card set and the error message "Total number of ports and polling rate are not compatible, check cnfsysparm" is displayed, change the polling interval using the cnfsysparm command, option 25. Before changing the polling interval, run the command dspstatsinfo to see if the number of ports is less than 300, less than 500, or greater than 500. To make the ports and polling interval compatible, change the polling interval as follows: to 5 minutes if the number of ports is less than 300, to 10 minutes if the number of ports is less than 500, and to 15 minutes if the number of ports is less than 500.
The addport command is required before the ports can be activated (upport). The optional <vport> identifier indicates a virtual port. Only BXM cards support virtual ports.
For BPX only, since Release 9.3.0, upln no longer automatically configures a port. You must use the addport command to add the port before you can use the addcon command. You can verify that the line has been activated by using the dsplns command.

addrmtlp (add remote loopback to connections)
The addrmtlp command places these types of channels in remote loopback mode:
•Voice
•Data
•Frame Relay port
•Frame Relay connection
•ATM connection
For voice connections, addrmtlp loops the information stream from the designated channel or group of channels on an incoming circuit line across the network and loops it back to the circuit line by way of the remote CDP or CVM. External test equipment can then test the integrity of the path at the T1 DS0 level. Figure 3-7 illustrates a remote loopback on a voice channel.
Figure 3-7 Remote Loopback on a Voice Channel
For data connections, addrmtlp transfers the information stream from the designated channels through the network and loops it back to the data port(s) through a remote SDP, HDM, LDM, or LDP. External test equipment can then test the integrity of the path. Figure 3-8 illustrates a data connection remote loopback.
Figure 3-8 Remote Loopback on a Data Connection
Prior to executing the loopback, the IGX node applies signaling template bit patterns to the A, B, C, and D signaling bits at the remote end to remove the connection from service. The loopback remains in place until removed by the dellp command. Only existing connections (those that have been entered with the add-on command) can be looped back. You cannot establish a remote loopback on a connection that is already looped back, either locally or remotely. (See the addloclp command for more information on local loopbacks.)
Use the dspcons command to see which connections are looped back. A flashing left parenthesis "("or right parenthesis ")" is used in the connections display to indicate a loopback. The direction and location of the parenthesis depends on whether the loopback is local or remote and which end of the connection was used to establish the loopback. A remote loopback initiated from the local end of the connection looks like this:
A remote loopback initiated from the remote end of the connection looks like this:
For remote loopback of Frame Relay connections, note that in remote loopback mode, if the transmit minimum bandwidth exceeds the receive minimum bandwidth, then loopback data may be dropped. For this reason, the connection speeds will be checked and the user will receive the following message if there is a problem:
Warning—Receiver's BW < Originator's BW-Data may be dropped
Because the addrmtlp command causes the connection to be removed from service, loopbacks should be used only when a service disruption can be tolerated. Local loopbacks are established with the addloclp command. Both local and remote loopbacks are removed by the dellp command. Loopbacks for data channels can also be initiated by pressing a push-button on the front of the associated data card.
Remote Loopbacks and the Port Concentrator Shelf
For Frame Relay remote loops, DLCI MUST be specified; entering only port number only generates an error message.
Unlike local loopbacks, remote loopbacks are not supported for Frame Relay ports; connections must be specified. Data incoming on the Frame Relay port is looped at the remote end FRM-2 or FRP-2 card, as shown in Figure 3-9.
Figure 3-9 Frame Relay Remote Loops
As shown, this test verifies the operation of IGX network components up to the interface with the remote-end FRM-2 or FRP-2. This test interrupts data traffic for only the connection specified by DLCI.
If a port concentrator is attached to the FRM-2 or FRP-2, the only difference in the loop is that the port specified to loop data is on the Port Concentrator, as shown in Figure 3-10.
Figure 3-10 Frame Relay Remote Loops with Port Concentrator
The addloclp and addlocrmtlp commands support the two-segment connection at the hub node port endpoint in a network of IGX hubs and SES interface shelves. The addloclp and addlocrmtlp commands are blocked at the interface shelf trunk endpoint. The addrmtlp command is not supported at either endpoint of the connection. You can use the dellp command to remove the local (or local remote) loopbacks that have been added; however, you cannot use the dellp command at the trunk endpoint of the connection—it will be blocked.

addshelf (add interface shelf or controller to a routing node or hub)
In a tiered network, adds an ATM link between:
•an IGX or BPX core switch shelf and an interface shelf; or
•a BXM card on a BPX node and a Label Switch Controller (LSC) such as a series 7200 or 7500 router; or
•a BXM card on a BPX node.
An MPLS controller is considered an interface shelf from the BPX's perspective.
The interface shelf can be one of these:
•An MGX 8220 shelf connected to a BPX node
•An MGX 8850 shelf connected to a BPX node
•An MPLS (Multiprotocol Label Switching) controller connected to a BPX node
•A Private Network to Network Interface (PNNI) Controller connected to a BPX node
•An IGX node connected to an IGX routing node that serves as a hub for the IGX/AF
•An SES (Service Expansion Shelf) connected to an IGX node
The signaling protocol that applies to the trunk on an interface shelf is Annex G. (Annex G is a bidirectional protocol defined in Recommendation Q.2931, used to monitor the status of connections across an UNI interface. The Annex G protocol is used in this release to pass connection status information between an IGX/BPX core switch shelf and an attached feeder.)
For example, the MGX 8850 interface shelf, or feeder, communicates over a UXM/UXM-E interface with the routing hub over Annex G LMI using AAL5 format.
Note Because tiered network capability is a paid option, personnel in the Cisco Technical Assistance Center (TAC) must Telnet to the unit and configure it as an interface shelf before you can execute addshelf.
Each IGX/AF, MGX 8220, MGX 8850, or SES shelf has one trunk that connects to the BPX or IGX node serving as an access hub. A BPX routing hub can support up to 16 T3 trunks to the interface shelves, which can be IGX/AF, MGX 8220, or MGX 8850 interface shelves. An IGX hub can support up to four trunks to the interface shelves, which can be IGX/AF or SES (Service Expansion Shelf) shelves.
Before it can carry traffic, you must "up" the trunk on an interface shelf (using uptrk on both the interface shelf and the IGX/BPX core switch shelf) and "add" it to the network (using addshelf). Also, a trunk must be free of major alarms before you can add it with the addshelf command.
Use the commands addshelf and addctrlr to add an MPLS or PNNI controller to the BPX. Use the command addshelf with option "v" to add a VSI shelf. This is used mainly for MPLS controllers. Use the command addctrlr to add a controller to a shelf that has LMI capabilities.
You can use an IGX as a feeder node to connect via a UXM IMA trunk to an IGX or BPX router node using IMATM. Use addshelf with the "I" option at the IGX node to add the feeder trunk connecting it to an IGX feeder node.

Release History
Previous to Release 9.2, WAN switching software supported the ability to configure the MGX 8220 as an interface shelf to the BPX. Release 9.1 introduced the ability for the MGX 8850 to serve as an interface shelf to a BPX routing hub. Release 9.2 introduced the ability for an SES (Service Expansion Shelf) to serve as an interface shelf to an IGX 8400 routing hub.
Release 9.2.20 supports:
•You can attach SES feeders to the routing network through an IGX 8400 routing hub using UXM/UXM-E and PXM trunks using UNI and NNI format. A routing hub can support up to four feeders.
•The LMI/Annex G signaling channel is used to communicate with the SES feeder through the SAR (Segmentation Assembly and Reassembly).
•UXM Feeder support provides voice, Frame Relay, and ATM data connections from feeder node to feeder node for a 2- or 3-segment network.
Signaling Channel Used by MGX 8850 and SES Interface Shelves Connecting to Routing Hubs
The SES interface shelf with a UXM/UXM-E interface communicates with the routing hub over an Annex G LMI interface by using AAL5 format.
Annex G is a bidirectional protocol used to monitor the status of connections across a UNI interface. This includes the real-time notification of the addition or deletion of connection segments and the ability to pass the availability (active state) or unavailability (inactive state) of the connections crossing this interface.
An SES feeder uses the Annex G protocol to pass connection status information between itself and an IGX 8400 routing hub. Similarly, an MGX 8850 feeder uses the Annex G signaling channel to pass connection status information between itself and a BPX routing hub.
The SES interface shelf communicates with an IGX routing hub through ATM cells. Thus, IP data destined for an IGX 8400 is encapsulated in an AAL5 ATM cell format.
addshelf Error Messages
Some of the possible error messages for the addshelf command:
•An MGX 8850 Interface Shelf already exists on this Hub
•Trunk is already added to the Network
•Trunk is in alarm
•An Interface Shelf already exists on this trunk
•Interface Shelf VPI out of range

Next Command:
The sample display shows that an SES was added on trunk 9.1 as an AAL5 type of interface shelf. (AAL5 is the ATM Adaptive Layer 5 protocol, which is an ATM standard interface that is used by the routing node or routing hub to communicate with the SES shelves.) Adding an IGX interface shelf is similar to adding an MPLS (Multiprotocol Label Switching) controller as an interface shelf.
The addshelf command will prompt for "Interface Shelf Type." Because the MGX 8220, MGX 8850, and the SES (Service Expansion Shelf) use the same Annex G LMI signaling protocol to communicate with an IGX routing hub, they all use the same interface shelf type of AAL5 (designated by the addshelf "X" option).
Adding a VSI Controller
The maximum number of controllers that can be attached to a given node is limited by the maximum number of feeders (16) that can be attached to a BPX hub. Therefore, the total number of feeders and controllers cannot exceed 16.
You add a VSI controller, such as an MPLS controller, to a switch by using the addshelf command with the vsi option. The vsi option of the addshelf command identifies VSI controllers and distinguishes them from interface shelves (feeders).
The VSI controllers are allocated a partition of the switch resources. VSI controllers manage their partition through the VSI interface. The controllers run the VSI master. The VSI master entity interacts with the VSI slave running on the BXMs through the VSI interface, to set up VSI connections using the resources in the partition assigned to the controller.
Two controllers that are intended to be used in a redundant configuration must specify the same partition when added to the node through the addshelf command.
When a controller is added to the node, switch software sets up the infrastructure so that the controllers can communicate with the slaves in the node. The VSI entities decide how and when to use these communication channels.
The controllers also require a communication channel between them. This channel could be in-band or out-of-band. When a controller is added to the switch, switch software sends controller information to the slaves. This information is advertised to all the controllers in the partition. The controllers may decide to use this information to set up an intermaster channel. Alternatively the controllers may use an out-of-band channel to communicate.
To add a controller to the node, use the addshelf command. You add a redundant controller in the normal way, except that it specifies a partition that may be already in use by another controller. The addshelf command allows for up to three controllers to manage the same partition.
One of the parameters that must be specified with the addshelf command when a VSI controller is added to the switch is the controller ID. This is a number between 1 and 32 that uniquely identifies the controller. Two different controllers must always have different controller IDs.
The management of resources on the VSI slaves requires that each slave in the node has a communication control VC to each of the controllers attached to the node. When a controller is added to the BCC via the addshelf command, the BCC sets up the set of master-slave connections between the new controller port and each of the active slaves in the switch. You specify the master-slave connections by using the <Control VPI> and <Control Start VCI> parameters. The default for these parameters is 0/0.
Note If you manage a tiered network through the command line interface, you can manage only Frame Relay interworking connections (ATFR) across the network. Three-segment connections for carrying serial data or voice between IGX/AFs is allowed, but you must manage them through WAN Manager.
Feature Mismatching to Verify VSI Support
The cnfrsrc and addshelf commands, in addition to other configuration commands, perform mismatch verification on the BXM and UXM cards. For example, the cnfrsrc and addshelf commands verify whether the cards both have VSI 2.0 support configured.
The Feature Mismatching capability does not check mismatched cards unless the actual feature has been enabled on the card. This allows for a graceful card migration from an older release.
Example (Redundant VSI Controller)
Add a redundant (more than one) VSI controller (as an interface shelf to a BPX node), on slot 11 on port 1, with a control partition of 1 and control ID of 2.

Adding an MPLS Controller
For MPLS to carry traffic, you must first up the link to an MPLS controller (by using uptrk) at the BPX node. You can then add the link to the network (by using addshelf).
The link must be free of major alarms before you can add it with the addshelf command.
Note Once you up a port on the BXM in either trunk or port mode by using either the uptrk or upport commands, respectively, you can up only those ports in the same mode.

addtrk (add a trunk between nodes)
You must add a trunk to the network before it can carry traffic. You need only to execute addtrk at one of the nodes terminating the trunk. Before you add a trunk to the network, you must have activated (or "upped") the trunk at both ends by using uptrk.
A trunk must be free of major alarms before you can add it. If you use addtrk to join two networks that were previously separate, the local node verifies that all node names and node numbers in both networks are unique before it adds the trunk.
You cannot add a trunk while any of these conditions are true:
•Another node is attempting to change the network topology by adding or deleting a trunk.
•Another node is notifying all nodes that it has been renamed.
•Another node is currently adding or deleting a connection in the network with the addcon or delcon command.
•An unreachable node exists in the network.
•Connections are rerouting.
•The node names or the node numbers across the two networks are not unique. Use the command and optional parameter dspnds +n to see the node numbers.
Warning When using the addtrk command, exercise caution when adding a new node to a network or one network to another network. With these particular operations, the user IDs and passwords may be replaced by those in the other network. Consult Customer Service before performing these operations.
Adding a Virtual Trunk
You can add a trunk as a physical trunk or a virtual trunk. A virtual trunk is a way to connect Cisco nodes through a public ATM cloud. You can define virtual trunks on BNI, BXM and UXM cards.
(Note that even though nodes running Release 9.2 can interoperate with 9.1 or 8.5 nodes, if you are running a network with mixed releases, you cannot add UXM and BXM virtual trunks because the networking messages are incompatible due to the virtual trunk number and different cell format on virtual trunks. BNI cards use STI cell format, and BXM and UXM cards use NNI cell format.)
To designate a trunk as a virtual trunk, you use a virtual trunk number, which is used to differentiate the virtual trunks within a physical port. (Refer to the BPX 8600 Series Reference for more information on virtual trunking.)
For the BXM card, you can define a maximum of 32 virtual trunks within one port. Valid virtual trunk numbers are 1-31 per port. The number of virtual trunks available is limited by the number of virtual interfaces (VIs) available on the card. Each logical trunk (physical or virtual) consumes on VI.
For the UXM card, you can define a maximum of 16 virtual trunks within one port. Valid virtual trunk numbers are 1-15.
The addtrk command will be blocked for virtual trunks configured for VSI.

addtrkred (add trunk redundancy)
Configures trunk redundancy on an ATM trunk. The addtrkred command specifies a backup trunk to the primary trunk. Applicable line types are T3 and E3. The redundancy scheme requires two sets of ATM trunk cards and two standard T3 or E3 cables (not Y-cables). Note the following characteristics of trunk redundancy:
•Applicable card sets are the AIT connected to a BNI card set on a BPX node.
•Execute addtrkred on an IGX but not on the BPX side.
•Primary and backup card sets must be in adjacent slots.
•After a primary trunk failure clears, the traffic automatically returns to the primary card set.
•Trunk redundancy is not compatible with virtual trunking.

addyred (add Y-cable redundancy)
Enables card redundancy for cards on the BPX and IGX. The addyred command also enables SONET Automatic Protection Switching (APS) across two BXM OC-3 or OC-12 cards. Use the addyred command to specify the slots of the primary and secondary cards that form the redundant pair. Redundancy applies to the entire card, and not specific trunks or lines. (The addyred command performs the same function as the addcdred alias command.)
Redundant card sets must have these characteristics:
•The primary and secondary card sets must be identical.
•Secondary card sets must not currently be active.
•Neither the primary nor secondary card set may already be part of a redundant set.
•When configuring APS 1+1, the primary and secondary card sets must be in adjacent slots. (Note that this restriction applies only to the BPX chassis for APS 1+1 redundancy.) See the "APS 1+1 Environment (Redundant Back Cards with Front Card Redundancy)" section for additional information on APS 1+1.
In both single and multiport card sets, if the secondary card set becomes active, the primary card set serves as its backup (assuming the primary card set is complete and not failed). You cannot use the addyred command if the primary and secondary slots are empty. If one or both of the card slots is empty, the addyred command will fail.
You must use the addyred command to configure a VSI slave redundant card. When a standby slave card is first started (either by inserting the card into the slot, or issuing the addyred command from the CLI console), the active slave forwards all VSI messages received from the master VSI controller card to the standby slave VSI controller card.
If cards reside in the primary and secondary slots, the system checks for card compatibility. Two types of incompatibility can occur: back card and jumper or cable inconsistencies. On SDI, FRI, and FTI cards, jumpers determine whether a port is configured as DCE or DTE. On LDI cards, either a DCE or DTE adapter cable connects to the LDI port. If incompatibilities exist, the message "Y-Cable Conflict" appears on the screen. Specific conflicts are listed in reverse video in the dspyred display. See the dspyred description for more information. For descriptions of the jumper positions and cabling, see the Cisco IGX 8400 Series Installation and Configuration manual.
The addyred commands (addyred, delyred, dspyred, prtyred, switchyred) perform feature mismatch checking on both the primary and secondary cards. For information on feature mismatch checking, refer to the BPX 8600 Series Installation and Configuration Guide. Also see the "Feature Mismatching" section for detailed information.
With the second phase of the Automatic Routing Management to PNNI migration introduced in Release 9.3.30, the BXM interface card supports the Extended LMI (XLMI) protocol. This protocol enables the exchange of neighbor discovery information between the BXM and AXSM over the AR-PNNI link. You cannot activate XLMI/ENNI when there are existing connections. Also in this release, ILMI Neighbor Discovery feature is also available for virtual ports on the BXM card.
With Release 9.3.30, addyred is NOT allowed in the following instances:
•When the secondary BXM card does not support LMI Neighbor Discovery and the primary BXM card supports LMI Neighbor Discovery and at least one port is running the XLMI protocol.
•If one card in the Y-redundant BXM pair is replaced, mismatch is declared when the original card pair supports LMI Neighbor Discovery and at least one port is configured for LMI Neighbor Discovery.
•If O.151 OAM is enabled on the primary card (using cnfcdparm) and the secondary card does not support the feature.
Note In the hybrid AR-PNNI network, both the active and standby BXM cards receive messages for connections that are added or deleted. Both cards maintain identical connection database views. However, there is no XLMI redundancy, and only the active BXM card exchanges connection status information with the adjacent AXSM. At switchover, the new active BXM card initiates an exchange with the adjacent AXSM to synchronize the AXSM's connection database.

Feature Mismatching
During addyred's mismatch checking, the following verifications are performed:
•A verification is performed to ensure that both the primary and secondary cards support features that are activated. For example, if the APS feature is configured on the primary card, and this feature is not available on the secondary card, you are blocked from using the addyred command. As another example, to ensure that cards with the Idle Code Suppression feature enabled on them are compatible, addyred blocks cards that have different idle code suppression capability.
•If the feature is not enabled, and the secondary card does not support similar feature sets, the (internal) logical database is updated to reflect this difference.
•Following a delyred command execution, the logical card's database is updated to reflect the primary card's capabilities.
With Release 9.3.10, addyred is NOT allowed if the BPX Neighbor Discovery Enable/Disable flag is set to ENABLED on any port on the primary card and the secondary card does not have the BPX Neighbor Discovery capability. An error message is displayed in this situation. The addyred is allowed if the BPX Neighbor Discovery Enable/Disable flag is NOT set to ENABLED on any port on the primary card. If the secondary card does not have the BPX Neighbor Discovery capability, the following events occur:
1. Mismatch is not declared.
2. Neighbor's information (Neighbor's IfName and Neighbor's IP Address) is deleted from all ports on the primary card.
3. BPX Neighbor Discovery Enable/Disable flags on all ports on the primary card are set to DISABLED (if previously set to ENABLED).
4. The logical card table(s) are updated to indicate that the BPX Neighbor Discovery feature is no longer supported.
5. CWM is notified via the Robust Port Update message.
Events 1 through 5 also occur in the following situations:
•A stand-alone BXM card with Neighbor Discovery capability and BPX Neighbor Discovery Enable/Disable flag set to either ENABLED or DISABLED on any port on the card is replaced with one that does not support the feature.
•One of the cards in a Y-redundant card pair (both cards with Neighbor Discovery capability and BPX Neighbor Discovery Enable/Disable flag set to either ENABLED or DISABLED on any port on the logical card) is replaced with one that does not support the feature.
Starting with Release 9.3.30, the BXM-E models DX and EX card slots can be configured to support 60K LCNs for VSI connections. For Y-cabled or APS 1+1 redundancy, the system checks the total physical channel number supported by each card in the pair. When addyred is executed, the lower value of the two cards becomes the attribute value for the logical card. If the logical card is configured to support 60K VSI LCN, mismatch is declared when a replacement card's attribute value of total physical channel number supported is not 60K-64.
APS 1+1 Environment (Redundant Back Cards with Front Card Redundancy)
The same numbered ports on adjacent BXM cards are used. A hardware, firmware, and software upgrade is required. (Firmware that supports APS 1+1 setup, and switch software Release 9.2 is required.)
The APS 1+1 feature requires two BXM front cards, an APS redundant frame assembly, and two redundant type BXM back cards. The two redundant BXM back cards are plugged into the APS redundant frame assembly. (Refer to the SONET APS Configuration chapter in the Cisco BPX 8600 Series Installation and Configuration guide for more information on APS hardware configuration.) The types of redundant back card and backplane sets required are:
Note Using only one front card and two back cards is not a valid configuration when adding APS capability, and APS alarm capability is reduced when the standby card is not available. You must configure card redundancy before you can configure APS redundancy.
Note When SONET Automatic Protection Switching (APS) is configured, you will not be able to use the addyred or delyred commands on a card configured for APS 1:1 architecture. That is, you will not be able to execute the addyred command, then configure the APS 1:1 architecture. Similarly, you will not be able to configure APS 1:1, then execute the addyred command. You will be blocked from executing these commands at the command line interface. Refer to the Cisco BPX 8600 Series Installation and Configuration manual for more information on configuring SONET APS 1+1 card and line redundancy for BXM OC-3 and OC-12 cards.
burnfwrev (burn firmware image into cards)
Burns a firmware image into the memory of a specific card. Before you use burnfwrev, the firmware image must already reside in the controller card's memory. (Use getfwrev to load the image to the controller.)
A few seconds after you enter burnfwrev, the system displays a screen similar to the one in Figure 3-10, then the Burn Address column starts to indicate the addresses that are being "burned." When burnfwrev finishes, the status changes to "Complete."
After all cards at a node have been updated with burnfwrev, enter the following to clear the firmware image from the controller card's buffer area:
getfwrev 0.0 node_name
Use the dspfwrev command to display the firmware image status on the controller card at any time after burnfwrev has finished.
At the SuperUser level (0), you can use burnfwrev only to change the revision level of a card's firmware. If the firmware revision would result in a new model number for the card, only a user with a higher privilege level can burn the firmware image. In this case, you would have to call the TAC to execute the command.

clrchstats (clear channel statistics)
Clears the gathered statistics for either a specific channel or all channels, including Frame Relay channels. When you enter a specific channel number, the current channel statistics display appears, asking if you want to clear the display. If you enter "*" (all channels) for the channel specification, the display prompts you to confirm whether you want to clear all channel statistics. This is sometimes referred to as a summary statistics command.
The Multilevel Channel Statistics lets you configure and display additional levels of statistics beyond level 1 statistics (for example, levels 2 and 3), as supported by the Multilevel Channels Statistics feature. You use the cnfcdparm command to configure the channels statistics level on the BXM or UXM cards.
For example, if you configure slot 5 to support level 3 channel statistics, all connections on that particular card are set to provide level 3 statistics. Switch software collects, displays, and propagates to Cisco WAN Manager the various statistics types. The channel statistic type vary in number and type based on the level of support provided by the BXM and UXM cards. You use the dspchstats and clrchstats to display and clear the statistics.

clrclkalm (clear alarm clock)
Clears the alarm status of a clock source, either circuit line or trunk, after a problem is cleared. Before the node can use the original clock source, you must clear the alarm with clrclkalm. The system displays no messages after execution.
The clock test runs continuously in a node, comparing the frequency of the node's clock source to a reference on the BCC/CC/control card. If a clock source is found to be outside preset frequency limits, it is declared defective and another clock source is selected. In order for the node to return to the original clock source, the alarm must be cleared by using the clrclkalm command. The alarm may be either a "Bad Clock Source" or "Bad Clock Path" alarm.
Syntax
clrclkalm <line type> <line number>
Parameters
Parameter Description<line type>
Specifies the type of line:
"L" indicates a line.
"T" indicates a trunk.<line number>
Specifies the number of the line or trunk.

clrcnf (clear configuration memory)
Clears the configuration memory at the current node and resets the node.
The clrcnf command erases most network configuration data. This configuration data includes connections, trunks, circuit lines, and so on, for the local node. You might need to use the clrcnf command when you upgrade the network with a new software release or when you move a node. A warning and a confirmation prompt appear before the command executes.
This command should be used only on a node that has not yet been placed in service or when the network configuration has been previously saved so it can be quickly reloaded. The configuration can be saved in one of several ways:
•On a Cisco WAN Manager terminal using the savecnf command. The node is then reloaded using the loadcnf command.
•On a standby controller card. Before entering the clrcnf command, remove the standby controller from its slot. The configuration data will be maintained in BRAM even though the power has been removed from the card.
Caution Use clrcnf with extreme caution. Typically, you should use clrcnf only if the Cisco TAC has instructed you to do so. This command can make the node unreachable to the network.

clrfrcportstats (clear FRC/FRM port statistics)
Clears port statistics for FRM-2 or FRP-2 physical ports connected to a Port Concentrator Shelf. To see the statistics that you clear with clrfrcportstats, execute dspfrcportstats. The controller card collects statistics from the FRM-2 or FRP-2 once per minute. Because clrfrcportstats clears statistics on the controller card, it might not clear statistics generated within the last minute.
Syntax
clrfrcportstats <slot.port | *>
Parameters
Parameter Description<slot.port | *>
Slot and port of the physical port. The range for port is 1-4. An asterisk (*) specifies all FRC-2/FRM-2 physical ports.

clrlnalm (clear circuit line alarm)
Clears the alarms associated with a circuit line. Since the statistical alarms associated with a circuit line have associated integration times, they can keep a major or minor alarm active for some time after the cause has been rectified. This command allows these alarms to be cleared, allowing any new alarms to be quickly identified. The clrlnalm command can clear only alarms caused by the collection of statistical data. Alarms caused by a network failure cannot be cleared. For example, an alarm caused by a collection of bipolar errors can be cleared, but an alarm caused by a card failure cannot. (Same as alias clrclnalm.)

clrtrkalm (clear trunk alarm)
Clears statistical alarms associated with either a physical or virtual trunk. Note that if a virtual trunk is specified for a command that configures information related to the physical port, then the physical port information is configured for all virtual trunks. This means that using clrtrkalm clears parameters on a logical trunk basis, but any changes automatically affect all trunks on the port when you change a physical option. Any changes you make to a virtual trunk on a port affect all virtual trunks on that port.
Since the statistical alarms associated with a trunk have associated integration times, they can keep a major or minor alarm active for some time after the cause has been rectified. The clrtrkalm allows these alarms to be cleared, allowing any new alarms to be quickly identified.
The clrtrkalm command can clear only alarms caused by the collection of statistical data. Alarms caused by a network failure cannot be cleared. For example, an alarm caused by a collection of bipolar errors can be cleared, but an alarm caused by a card failure cannot.
Note A virtual trunk also has trunk port alarms that are shared with all the other virtual trunks on that port. You clear and set these alarms together for all the virtual trunks sharing the same port.
Alarms for the BXM and UXM card types are cleared and displayed differently.

cnfasm (configure ASM card)
Sets configurable parameters associated with the BPX Alarm and Status Monitor card in slot 15. Because this card always resides in slot 15, entering the slot number is unnecessary. Robust alarms are generated for these alarm conditions:
•Power supply, temperature, fan, and DC-voltage level alarms. (Some of these conditions already generate Robust Alarms on the IGX.)
•Connection AIS alarm
•Bus failure
•External clock source failure
•Multiple invalid login attempts on a user port (potential security threat)
•Excessive CPU and memory usage on switch processor card
These alarm conditions above appear in the maintenance log or in the node command line interface commands (dspasm), and are not also reported as SNMP trap to the customer NMS. (Such traps are generated by the Cisco WAN Manager RTM proxy upon receiving Robust Alarms from a switch.)
In Release 9.2 and above, robust alarms are generated by the BPX when power and temperature alarm conditions are detected by the ASM card. The ASM card monitors and reports events involving:
•Power supplies
•Cabinet temperature
•Cooling fan speed
•DC-voltage level
You configure and control the reporting of these events by using the cnfasm command, where you can enable or disable each alarm. For power supply failure/removal events, you can also specify the alarm class (that is, Major vs. Minor).
A robust alarm is generated by these events:
•The IGX platform when a DC-voltage out-of-range condition occurs.
•All switch platforms (IGX, BPX) when:
–An Alarm Indicator Signal (AIS) condition is detected on a PVC. The alarm now has an NNI Status field that previously appeared in the Connection NNI Alarm message.
–A bus failure or failure cleared event occurs. (In releases previous to Release 9.2, such events are reported through maintenance log messages.)
–An external clock source failure or failure cleared event occurs.
–The number of successive invalid login attempts on a user port exceeds the current threshold setting on the switch. You set the threshold by using the cnfsysparm command.)
–The processor card CPU utilization of the IDLE process falls below a fixed threshold. The purpose of the alarm is to indicate the possible degradation of service caused by processor load reaching an abnormally high level.

cnfatmcls (configure class template)
Use cnfatmcls to modify the ten Cisco-supplied class templates for ATM connection configuration. (The addcon command can take a class as an input.)
When you enter the number of the class to configure, the display shows the current value of each parameter in the class. For each item in the class, a prompt appears for changing or keeping the current value.
You can use cnfatmcls and cnfcls to configure the rt-VBR ATM connection class. You can use dspatmcls and dspcls to display the connection parameters for the rt-VBR and nrt-VBR connection classes.
The rt-VBR connections are configured per class 3 service parameters, and nrt-VBR connections are configured per class 2 service parameters. You can change these class parameters by using the cnfcls/cnfatmcls commands, or you can enter the parameters individually for each connection by specifying yes to the extended parameters prompt of the addcon command.
Note For a new node running software Release 9.2.20 or later, the rt-VBR connection class number is 3. An upgraded node will retain existing connection classes. Therefore, it won't have the rt-VBR connection class 3. However, you can configure the connection classes to desired service and parameters by using the cnfcls/cnfatmcls commands. For nrt-VBR connections in a new node, running Release 9.2.20, a number of connection classes are preconfigured, including 2, 4, 5, and 6.

cnfbmpparm (configure priority bumping)
Configures priority bumping parameters.
Priority bumping requires a number of configuration parameters saved in the BRAM and sent to the Standby Processor card. The parameters consist of a feature activation flag, a bundle size, and a set of seven CoS bands (0-7), implicitly defining eight CoS bands. Unlike Automatic Routing Management capabilities, which include a number of different operational flavors, priority bumping is strictly a CoS-based (or, more accurately, band-based) algorithm. Each band is defined by the low-end CoS value within the band. Band 0 (implicitly defined) is the most important one, whereas Band 7 is the least important. Each connection within a band is equally important, despite the fact that it might be tagged with a different CoS. Note that Band 0 is not bumpable.
A minimum of two bands are required to be defined for the priority bumping feature to work. A network with only one band is equivalent to having the priority bumping feature disabled.
The entire network must be upgraded to 9.3.0 in order for the priority bumping feature to be operational.
Use these steps to set up priority bumping:
Step 1 For a BPX switch, a license must be purchased for each BPX node on the network using the cnfswfunc 6 e command (see the first Example). The Cisco System Engineer enters the password to purchase priority bumping license. The license is granted immediately with the correct password.
Step 2 Before you enable priority bumping, ensure that a minimum of two bands exist by using the dspbmpparm command.
Caution If less than two bands exist, the BCC aborts.
The following sample output shows that two bands do not exist:
XXX TN Cisco BPX 8620 9.3.0 Feb. 22 2006 12:12 GMT

Priority Bumping Active on this node [ NO]
Number of bumpable Bands [ 0]
Last Command: dspbmpparm
If a minimum of two bands do not exist, use the cnfbmpparm command to create the bands. The following sample output shows the default values for the bumping bands:

Band 6 [ 12] (D)
Band 7 [ 14] (D)
Last Command: cnfbmpparm 3 2 4 6 8 10 12 14
Step 3 From either an IGX switch or a BPX switch, enable priority bumping from any node on the network using the cnfbmpparm command.
Parameter changes made at one node are propagated to the rest of the network, then updated both to the BRAM and Standby Processor card.
The default configuration when priority bumping is enabled is shown below:
Step 4 To test priority bumping (optional) you can create an environment to "stress" bandwidth resources and see how the feature works. For example:
1. Delete a trunk.
2. Physically remove a cable to a connection.
3. Add connections to create limited bandwidth resources on a trunk.
You then can use the dspcons command to view connection routing.
Step 5 To display the CoS-based loads, use the dspload command. Information about the CoS-based loads within each band helps you determine where to add connections in a priority bumping environment. The loads are displayed for a trunk. The total capacity is shown at the bottom of the display, and the load for each Band is displayed at the top. Any connection that is added to a band could bump and utilize bandwidth resources for the band that follows it; for example, adding a connection to Band 5 can bump connections in Band 6 and Band 7, allowing connections in Band 5 to utilize the bandwidth from those bands.
Limitations
•Priority bumping does not support a situation when VPC CONIDs (or any resources other than bandwidth and LCN) are in short supply.
•Priority bumping can only be activated when all nodes are upgraded to Release 9.3.0 switch software, or higher.
•In a 9.3 network, there can be some nodes (BPX only) that do not purchase the priority bumping feature. Consequently, they are not capable of participating in the priority bumping operations. These nodes are not chosen during route selection unless the trunks leading to or from the nodes have sufficient network resources.
•The maximum number of low priority connections that can be bumped in each attempt to route a high priority connection is 1023.
•The maximum number of connections that can be bundled in a routing attempt is 50.

Example
Default Setup, Eight CoS Bands.
The default configuration is priority bumping disabled. However, when the feature is simply enabled (without changing the other banding parameters), the network would operate with eight CoS bands.
Example
Refined Granularity of CoS Banding.
A sample PB_Band configuration of 1, 2, 3, 4, 5, 11 and 13 provides a better granularity of CoS banding at the more important end of the spectrum.
Another sample PB_Band configuration of 3, 5, 8, 12, 13, 14 and 15 provides a better granularity of CoS banding at the less important end of the spectrum.
Example
Reduced CoS Banding, Better Operational Performance.
A sample PB_Band configuration of 1, 2, 8, 9, 9, 9 and 9 provides a reduced CoS banding, thus allowing better routing performance (with fewer iterations through the bands).
This screen illustrates how the bands are configured, then displayed.

cnfbpnv (set backplane type to new)
Use the command cnfbpnv to configure the backplane, if the backplane is so enabled. This operation is necessary in some instances to program the NOVRAM.
Issue the dspbpnv command to see the NOVRAM setting. For some operations, it is necessary to verify the NOVRAM in order to ensure feature compatibility. For example, in order for the BPX 8600 to operate at 19.2 Gbps with the BCC-4V, it must have the NOVRAM Word #2 set to 0001 (which indicates that the backplane version is new). If it instead has the NOVRAM Word#2 set to 0000 (indicating that the backplane version is old) the switch cannot run with a 19.2 Gbps peak throughput. If you visually verify that the backplane is a 19.2 Gbps backplane (see note below), but the backplane NOVRAM Word #2 has not been set to 0001, then issue the cnfbpnv command to program the NOVRAM.
Step 1 Enter cnfbpnv, and the response is:
Are you sure this is a new backplane (y/n)
Enter y
Step 2 Use the command dspbpnv to confirm the change. It should display:
Word #2 =0001
Note The 19.2 backplane can be visually identified by the small white card slot fuses at the bottom rear of the backplane. These fuses are approximately 1/4 inch high and1/8 inch wide. The 9.6 Gbps backplane does not have these fuses. If the BPX switch is a late model, then a 19.2 Gbps backplane is installed.

cnfbusbw (configure UXM card bus bandwidth)
Configures the amount of bandwidth allocated on the bus for a specified UXM card. The default amount of bus bandwidth allocated depends on the connection type you are adding; 77 Mbps (1/2 OC-3 rate) of bus bandwidth is allocated to an OC-3 port card when the first line is upped. For the T3/E3 line, 44/34 Mbps (T3/E3 rate) is allocated as default bus bandwidth. For a T1/E1 line, the amount of bandwidth allocated will be enough for all T1/E1 lines supported on the card.
After the default bus bandwidth is allocated, the system will not allocate any more bus bandwidth to the card when you activate more lines, so you must manually allocate the bus bandwidth to the card using the cnfbusbw command. All ports on the UXM in the selected slot are dynamically reconfigured according to the new parameters.

cnfcassw (configure CAS switching)
Configures a UVM to convert channel associated signaling (CAS) and dual-tone multi-frequency (DTMF) tones to common channel signaling (CCS) call control messages. This conversion is necessary for voice networks in which a Voice Network Switch (VNS) uses SVCs to route calls from a CAS-based PBX through a WAN. Model B or later firmware on the UVM is necessary.
Before you can execute cnfcassw:
•The line to which you apply cnfcassw must be up.
•If any connections exist on the line, you cannot change the cnfcassw parameters. However, you can execute the command to see the current parameters in the cnfcassw display.
•You cannot configure a line for both CAS-switching and pass-through.
•With CAS-switching on a UVM that has Y-cable redundancy, the call state of each connection is lost in the event of a switch-over.
Syntax
cnfcassw <line> <mode> <CCS type> <CAS type> <conn type> <country code>
<interdigit timeout> <tone level> <DTMF duration> <idle pattern> <parameters 6-18>
Note For the initial implementation of CAS switching, you should specify only port 1 for the line parameter (where line has the format slot.port) and select "PBX-end" for mode.

cnfcdparm (configure card parameters)
Configures card level functionality, including the level of channel statistics, the selection of VC merge, and support for O.151 OAM cell format, a non-standard format still used by some service providers instead of the standard I.610 OAM cell format.
This command supports the multilevel channel statistics feature, which lets you configure and display additional levels of statistics on a BXM or UXM card.
Configuration of the channel statistic level is a slot-based parameter. For example, if slot 5 is configured to support level 3 channel statistics, all connections on the card in slot 5 will be set to level 3 statistics.
The multilevel channel statistics feature is supported on the BPX and IGX platforms, for BXM and UXM cards. (Refer to release notes for card firmware release requirements.) The multilevel channel statistics feature requires switch software to collect, display, and propagate to Cisco WAN Manager the various statistics types. The channel statistic types vary in number and type based upon the level of support provided by the BXM and UXM cards. For additional information see the "Multilevel Channel Statistics Support" section.
Apart from the cnfcdparm command that you use to configure the channel statistic level on the BXM/UXM cards, you use the following commands to configure and display BXM and UXM card statistics:
•Summary Statistics Commands: dspchstats, clrchstats
•Interval Statistics Commands: dspchstathist, dspchstatcnf, cnfchanstats (statistics information collected by these commands is sent to Cisco WAN Manager)

Multilevel Channel Statistics Support
The number of statistics available are based upon the statistics level programmed on the BXM or UXM card. Table 3-16 lists the channel statistics available on the BXM and UXM cards. The four different levels supported are shown, along with the statistics field description as it appears on the related statistics screens (dspchstats, cnfcdparm, clrchstats, dspchstathist, dspchstatcnf, cnfchanstats).
However, the cnfcdparm command will not allow you to change the statistics level if the card is active. The switch software detects the current channel statistics level available on the UXM or BXM card. Also, switch software performs these card mismatch verification:
•When a card is inserted, if the channel statistic level decreases from the entry in the logical card database, the card will mismatch.
•When a card is inserted, if the channel statistic level increases from the entry in the logical card database, the card will not mismatch. The logical card database will NOT be updated with the increased channel statistic level value, and you will have available only the number of statistics described on the primary card.
•During the Y-cable mismatch verification, if the secondary card has a smaller channel statistic level, then the primary card (logical card) and the secondary card will mismatch. During the Y-cable mismatch verification, if the channel statistic level is larger on the secondary card, the card will not mismatch. The Y-cable will continue to operate based on the number of statistics available on the primary/logical card.

cnfcftst (configure communication fail test pattern)
The communication fail test pattern is used to periodically test for failure of nodes to communicate with each other. This test pattern is also used to recover from communication fail conditions.
A communication fail is defined as a loss of controller communication over one or more trunks to a particular node. A communication fail differs from a communication break condition in that the node may be reachable over other paths. The communication fail test is used to test the failed trunk for proper controller traffic.
Use cnfcftst to configure the communication fail test pattern byte by byte. It defaults to a pattern of 4 bytes of 1s followed by 4 bytes of 0s. Varying the length of the test pattern makes the communications test more or less rigorous. Changing the characters determines the pattern sensitivity for strings of less than 14 bytes.
The dspcftst command displays the current communication test pattern. The parameters used for declaring and clearing communication fails are set by the cnfnodeparm command.

cnfchadv (configure channel adaptive voice)
Enables the adaptive voice (ADV) feature for individual channels. ADV must also be enabled at each node that terminates the connection. The channel-specific cnfchadv has no effect at nodes that do not support ADV enabled.
If the ADV feature is enabled for a channel with a "c" or "v" connections, VAD is automatically disabled on that channel when trunk bandwidth is available and enabled when trunk bandwidth is needed. If the Adaptive Voice feature is not enabled for a channel with a "c" or "v" connections, VAD is always turned on for that channel. In order for a voice ("c" or "v") connection to use ADV, both ends must have ADV enabled by the cnfchadv command.

Enables or disables Data Frame Multiplexing (DFM) for individual channels and sets the DFM parameters for the channels. The default state when the DFM feature is activated on a card is enabled. Because DFM is a purchased option, the Cisco Technical Assistance Center (TAC) must activate on the applicable nodes before you use the cnfchdfm command.
The DFM feature must be both installed and enabled. The DFM feature must be installed through software control at each node terminating the connection. If DFM is not installed for a pertinent node in the network, the cnfchdfm command has no effect at that node. Furthermore, you must use cnfchdfm at both ends of the connection to enable DFM.

cnfchdl (configure dial type for channels)
Configures the dial type for a channel or set of channels. The dial type may be inband, pulse, or user-configured. The user-configured option allows non-default timing values to be used. The parameters associated with the cnfchdl command are timing constants used to ensure that signaling pulses are not distorted in time by transmission through the network.
•Dial type determines the signaling message timing for a connection. Dial type is ignored for DS0 data connections.
•When you add an inband or pulse dial type to a channel, the channel configuration screen appears, showing the designated dial types for each channel.
•When you add a user-configured dial type, a more detailed screen appears, showing the dial type as well as the signaling delay, minimum wink, interdigit times, and playout delay.
If you select inband, the node assumes that the A and B bits are not used for loop-disconnect dialing. Therefore, any change in signaling bit status goes in a packet to the far end of the connection.
If you select pulse, the transmitting node waits (normally 72 ms) after an A or B bit transition for another transition to arrive. If a transition arrives, the new transition goes into the same signaling packet that is sent to the far end of the connection. This step increases the delay of the signaling transition across the network but decreases the amount of trunk bandwidth used for signaling.
If the default timings are not correct for the network, you must configure the options. The dialing type should be set correctly. If a connection-designated pulse is used for inband signaling, a greater than necessary delay across the network results. If a connection-designated inband is used for pulse signaling, the relative timing of signaling transitions may be lost and so distort the pulses.

cnfcheia (configure EIA update rate for channels)
Sets the sampling rate for the updating EIA control leads. You can set this rate from 0 (no sampling) to packet-generation rate for the EIA leads associated with the channel.
At 20 updates/second, the control leads are polled for changes every 50 msec. Therefore, changes occurring more rapidly than that might not be detected. If there is no change in EIA lead status, no packet is sent. A minimum of one update per second is sent if the maximum update rate chosen is from 1 to 20.
If the connection is configured in such a way that an implied isochronous clock is detected, the update rate is always 20 per second in the same direction as that of the clock signal. For 1.544 Mbps data connections, this defaults to 0. This does not affect EIA sampling rates of fast EIA or embedded EIA leads.

cnfchstats (configure channel statistics collection)
Enables statistics collection for various channel parameters. The cnfchstats command is sometimes referred to as an "interval statistics" command—the statistics information collected is propagated to Cisco WAN Manager.
To configure the channel statistics level on the BXM and UXM card, use the cnfcdparm command. This command lets you configure a specific card slot to support additional levels of statistics (levels 2 and 3) that were supported in releases previous to Release 9.2 (level 1). See the cnfcdparm command for more information.
This debug command enables statistics collecting for channel parameters. Table 3-18 lists the statistics by type. Not all statistic types are available for all connections. Only valid statistics are displayed for you to select; inapplicable statistics appear in gray. If you are unsure of the size parameter to specify, select four bytes per sample.
The dspchstatcnf command displays the channel statistics configuration. Statistics are collected by and displayed on the Cisco WAN Manager workstation. Cisco WAN Manager allows statistics collection to be customized. You can disable a Cisco WAN Manager-enabled channel statistic by specifying the optional node name of the workstation as the last parameter on the command line.

This Command: cnfchstats 9.2.1.100
Statistic Type:
cnfchts (configure channel timestamp)
Configures a pre-aging parameter for data channels. Applicable cards are the SDP, LPD, LDM, and HDM. Applicable traffic is time-stamped data.
This command configures the pre-age parameter for data channels. The pre-age parameter specifies the initial age of a time-stamped packet. With a non-zero pre-age, the packet has less time to wait at the destination before it reaches the Max Time-Stamped Packet Age and is taken out of the ingress queue. (Data channels with the greater pre-age value are processed sooner.) However, if the pre-age value is too high because of queuing delays in the network, packets could be discarded because they appear too old at the destination.
The value you enter for pre-age should be a multiple of 250 microseconds (otherwise, the system rounds the value down to the nearest multiple of 250 microseconds). The default value is 0. Acceptable values are in the range 0 to the Max Time Stamped Packet Age (set by the cnfsysparm command). After you change a time-stamp, the connection should be rerouted or restarted for the new value to take effect.
Note You can see the value for pre-age in the screen display for the dspchcnf command. If dspchcnf is entered at a user-privilege level below SuperUser level, the pre-age parameter does not appear in the dspchcnf output.
Syntax
cnfchts <channel> <pre-age>

cnfchutl (configure channel utilization)
Informs the system software of the expected utilization rate of connections with traffic-dependent compression algorithms (voice connections with VAD, data connections with DFM, Frame Relay connections). The software load model then takes the user-specified rate of the connection and modifies it by using the percent of utilization you specify with cnfchutl. The resulting rate is used in calculations for loading trunks. The load model uses these figures instead of calculated estimates from real traffic patterns.
For the full benefits of the compression algorithms to be used, the default utilizations should be modified after traffic studies have been performed. Traffic studies of Frame Relay connections should be used to determine optimum utilization settings. When calculating loads in a network, the load allocated to a connection is:
channel utilization x full load for the connection type
For example, with a channel utilization of 50percent and a full load of 480 packets per second, the load allocated to a connection is:
0.50 x 480 pps = 240 pps
For voice connections with VAD turned off, the bandwidth allocated is always the maximum bandwidth for the connection type. In other words, the utilization, although configurable, is ignored for a voice channel without VAD and a data channel without DFM.
If you use cnfchutl to increase the utilization of a connection, the system verifies that the additional bandwidth is available on the connection's current route. If the bandwidth is not available, the system attempts to reroute the connection. If no other route is found, the connection is failed.
If you use cnfchutl to decrease the utilization of a connection, the system makes the bandwidth available to other connections that require a route. The screen displayed by the cnfchutl command depends upon whether a data channel, voice channel, or Frame Relay channel is specified.

cnfclksrc (configure network clock source)
Specifies a network-wide clock source. The clocking scheme ensures that all nodes in the network automatically synchronize to the nearest, most stable clock available. After you specify a clock source, the location and type of the network clock source goes out to all nodes in the network. This synchronization remains in effect despite line failures, power outages, controller card switchovers, line repairs, and the joining of subnetworks and all other network topology changes. Each node in the network maintains a list of the available clock sources for the network.
A clock source can be:
•a line (L)
•a trunk (T)
•an external source (E)
The clock type can be:
•primary (P)
•secondary (S)
•tertiary (T)
To remove a clock source, enter its type as "r" at the end of the cnfclksrc command line.
Designation of the clock type depends on the stratum (or stability) of the clock source. In a large network, for example, you could designate all stratum 2 clocks as "primary," all stratum 3 clocks as "secondary," and all stratum 4 clocks as "tertiary." The network regards all primary clocks as equal in the network clocking hierarchy, regards all secondary clocks as equal, and regards all tertiary clocks as equal. Each node synchronizes to the highest stratum clock source that is available. If multiple, equal clock sources are available, the node synchronizes to the source that is physically the closest. If none of the sources is available, the network synchronizes to the internal oscillator of one of the nodes in the network.
When you are planning clock sources, consider these points:
•The dspclksrcs command displays all clock sources in a network. The dspcurclk command displays the clock source that a specific node is currently using and the path between the source and the local node.
•To avoid unnecessary clock disruptions, configure all primary clock sources for the network first.
•A line must be upped and not in an alarm before you can configure it as a network clock source.
•Before you define a trunk as a clock source, use cnftrk to specify that the trunk does not pass synchronization.

cnfclnsigparm (configure circuit line signaling parameters)
Configures signaling parameters for a UVM or CVM.
The CVM & UVM Heartbeat parameter (option 1) is the rate, in seconds, at which the card sends a signaling (ABCD bits) state update to the other end of the connection, even when there is no change in the state of the signaling bits. This is done because signaling packets are time-stamped data packets, and there is a small chance that a signaling packet might be discarded somewhere in the network. This mechanism is a recovery mechanism to ensure that on-hook and off-hook notifications are not lost.
Increasing this interval will probably have no impact as long as none of the normal signaling time-stamped data packets are discarded in the network.

cnfcls (configure class template)
Modify the ten Cisco-supplied class templates for connection configuration. (The addcon command can take a class as an input.)
When you enter the number of the class to configure, the display shows the current value of each parameter in the class. For each item in the class, a prompt appears for changing or keeping the current value.
You can use cnfatmcls and cnfcls to configure the rt-VBR ATM connection class. You can use dspatmcls and dspcls to display the connection parameters for the rt-VBR and nrt-VBR connection classes.
The rt-VBR connections are configured per class 3 service parameters, and nrt-VBR connections are configured per class 2 service parameters. You can change these class parameters by using the cnfcls or cnfatmcls commands, or the parameters can be entered individually for each connection by specifying yes to the extended parameters prompt of the addcon command.
Note For a new node running software Release 9.2.20 or later, the rt-VBR connection class number is 3. An upgraded node will retain existing connection classes. Therefore, it cannot have the rt-VBR connection class 3. However, you can configure the connection classes to desired service and parameters by using the cnfcls/cnfatmcls commands. For nrt-VBR connections in a new node, a number of connection classes are pre-configured, including 2, 4, 5, and 6.

cnfcmparm (configure connection management parameters)
Configure various connection management parameters for the node. This command configures parameters (see Table 3-20 for parameter values) that affect Adaptive Voice, Rerouting, and Courtesy Up/Down. These parameters are used only at the local node.
The cnfcmparm command is used to enable cost-based route selection and the use of delay as the trunk cost. By default, delay is enabled. This worst-case delay for each connection type is calculated from the configured voice and non-time-stamped trunk queue depths.
For delay sensitive connections on the IGX (voice and non-time-stamped), the worst-case trunk delay can be used as the per-trunk cost.
For delay sensitive connections on the BPX (ATM CBR), end-to-end delay is not used as a routing constraint in Automatic Routing Management.

cnfcond (configure conditioning template)
Creates a conditioning template that specifies the bit patterns to be transmitted for each of the T1 and E1 timeslots and their A, B, C, and D signaling bits while the channel is in the failed state. Its purpose is to prevent the signaling bits from returning to the idle (on-hook) bit pattern during a channel failure and to force a known bit pattern (usually busy). If a connection fails and the template has been specified as the conditioning template for the failed connection, the data parameter in the template is transmitted in the channels timeslot, and the A, B, C, and D bits are processed according to the specified parameters.
A two-character sequence in the ID parameter field identifies the template. The Data Pattern field displays the pattern transmitted in the channels timeslot. The Signaling Pattern field displays the pattern transmitted in the channel's A, B, C, and D signaling bit positions. Each of the A, B, C, and D signaling bits are specified independently and may be held high or low or toggled to the on-hook condition for a short time then off-hook (the name of this latter action is a wink). You can control the timing of the bit-toggling by specifying the duration of winks in increments of 50 ms.
A typical failure response is for the node to:
1. Transmit idle characters in the channel's timeslot
2. Signal off-hook for a period of 2 seconds
3. Return permanently to the on-hook condition

cnfcos (configure CoS)
Determines the priority for rerouting a connection. You determine the priority by specifying a delay before the network reroutes one or more failed connections. The CoS applies to:
•A single connection
•A range of connections
•A connection group
When connections have failed (typically due to a trunk failure), the network reroutes them according to priorities that are set primarily by the class of service (CoS). The value of CoS is the number of seconds the network waits before it begins to reroute the connection, so the CoS determines the rerouting order for connections owned by a node. The range of possible CoS values is 0-15.
The number of connections in a network has an effect on the increment between CoS values you should use. For larger numbers of connections, you should allow more time to reroute the connections in a class. To facilitate the greater time required to reroute larger numbers of connections, use a larger increment between CoS values. In a larger network, for example, you could specify CoS values that are 3 seconds apart (such as 0, 3, 6, 9, 12, and so on, for example). For a network with less traffic, assign CoS values in increments of 1 or 2. This strategy ensures that all connections of a given CoS reroute before the connections with the next CoS start to reroute.

cnfdate (configure date and time)
Sets the date and time for the entire network. The node broadcasts the specified date and time to every node in the network. The time displayed at each node is consistent with the time zone where the node resides. (See the cnftmzn description.) For the first-time configuration of the date and time in a network, cnfdate requires all the parameters except for second. The default for second is 0. If a date and time already exist in the network, the defaults are the existing values at the moment you enter the cnfdate command. Note that changes to date and time alter the time-stamps on WAN Manager statistics.

cnfdch (configure voice connection for idle code suppression)
Configure a super-rate data connection that has idle code suppression (ICS) enabled or disabled, before adding a connection. The ICS information in the cnfdch screen is identical to that of dspchcnf.
The idle code suppression feature provides a way to stop FastPacket generation on an Nx64 super-rate PVC connection when the connected PBX has terminated a video call and there are no video calls in progress. It enables the UVM and CVM to detect the on-hook condition of video conferencing calls. No video traffic will be generated when a video call has terminated. Traffic on the data network is therefore reduced.
During the on-hook phase, FastPacket generation ceases, resulting in more trunk bandwidth becoming available. All connections that use ForeSight can use this unused bandwidth, resulting in higher information rate.
Because there are multiple channels involved in an Nx64 data connection, the idle code suppression configuration of the first channel in the Nx64 channel will be used for the entire connection bandwidth.
Configuration must be done for each endpoint of a connection. When the state of an ICS connection changes, no network message is sent to the other end. You can choose to configure the other end if ICS is supported on the other end also. To maximize the benefit of the idle code suppression feature, you should enable ICS on both endpoints of the connection.
If some of the specified channels do not yet have any connection attached, those channels will be initialized to a data type channel.
To interwork with HDM/LDM/SDP/LDP cards, idle code suppression on UVM/CVM/CDP channel will be turned off for any super-rate connection that also terminates on HDM/LDM/SDP/LDP.
All super-rate data connections will have their ICS state set to "disabled" state unless they have been specifically configured with the cnfdch command to be enabled, or through Cisco WAN Manager (or another SNMP manager application).
Use the cnfdchl command to configure a channel before you add a connection. The configuration remains the same when connections are removed and added again. This configuration will be removed when the associated line is deactivated.
The cnfdch command is available for level 2 users and above; that is, you must have at least privilege level 2 or above to use this command.
The cnfdch command is blocked if one or more specified channels is carrying a voice connection (including t-type).
The cnfdch command prompts you to enable or disable idle code suppression:

How Idle Code Suppression Works
When a video call terminates, the PBX generates the appropriate line idle code (for example, 0x7f for mu-law). Per ITU H.221 video coding scheme, no byte will be repeated on one DS0 for more than
80 times. In the case of BONDING protocol, the maximum is 256 (32 msec). The firmware can distinguish a video call and an idle channel carrying idle code. Idle code suppression is not programmable. Any byte that repeats for more than 32 msec in all DS0s in a super-rate connection will be suppressed.Switch software determines idle code suppression capability on a card based on firmware model and revision number (for example, it considers that the CVM card supports idle code suppression starting with model B revision E firmware).
The idle code suppression feature for the UVM and CVM cards on the IGX detects the idle (on-hook) state of a video call, which uses an Nx64K data connection, and suppresses packet transmission during this idle condition. The UVM or CVM at the far end plays out the idle code during this time. You disable or enable and display the status of idle code suppression on a per-connection basis through the switch software CLI cnfdch and dspchcnf commands.
The UVM and CVM card firmware identifies an on-hook or idle condition by detecting repetition of idle codes. These codes can be present in the regular video traffic also (that is, in H.221 or BONDING frames). The code must repeat a certain number of times before it can be concluded that the call is on-hook. It is not necessary to look for specific idle codes. Any byte-code repeating beyond the threshold (about 32 ms) indicates idle channels. The firmware monitors byte repetition on each Nx64 connection for which this feature is enabled. On detecting repetition beyond the specified threshold, FastPacket generation for such a connection would cease. This results in the remote side of the connection to under-run. In this condition, it would transmit the previously transmitted byte on each DS0 for the connection. The UVM/CVM continues to monitor DS0s for the connection to detect a change in data received. Any change would indicate an off-hook condition, after which FastPacket transmission would resume.
The idle code suppression feature consists of IGX switch software Release 9.2, and requires UVM model E firmware and CVM/CDP model B revision E firmware. The new UVM/CVM/CDP firmware ensures that idle code suppression can interoperate with UVM/CVM/CDP cards that do not have idle code suppression capability. Such a configuration means that FastPacket generation stops in one direction while the other end continues to generate FastPackets. This behaves exactly the same as enabling idle code suppression on one side but not on the other side.
All back card types supported by UVM/CVM/CDP support idle code suppression.
Interface with Cisco WAN Manager and Other Network Management Systems
The SNMP agent interface on the IGX provides the following operations: Get/Set of MIB information of the desired state of idle code suppression (enabled/disabled).
If a request fails, a General Error is returned to Cisco WAN Manager. An error string is logged in the switch software error table. Cisco WAN Manager can then optionally obtain the error string from switch software. Examples of error messages are "Card in slot does not support Idle Code Suppression" and "E1 CAS and Voice Channels - Not Configured".
Inserting/Removing Cards (Idle Code Suppression Mismatch)
Given an active non-Y-redundant UVM/CVM/CDP card without ICS support, upgrades to a card with ICS are allowed. However, you cannot downgrade a card with ICS capability to a card that does not support ICS (see Table 3-21).
Given a pair of cards in a Y-redundancy configuration, whether any of them is active or not, they must have the same ICS capability (see Table 3-22).

Upgrading and Downgrading the Idle Code Suppression Feature
Given an active non-Y-redundant UVM/CVM/CDP card (see Table 3-24) without idle code suppression support, an upgrade to a card with ICS support is allowed. Downgrading a card with ICS capability to a card without ICS capability is not allowed.
Upgrading the ICS feature to a Y-redundancy pair (see Table 3-25) that does not support the ICS feature is not allowed. The Y-redundancy pair must be deleted first to upgrade the feature. After both cards complete the ICS upgrade, the cards can be added as a Y-redundancy pair.

Limitations with Idle Code Suppression
T-type connections are not supported. On a VNS controlled network, t-type SVCs are used for video calls. VNS does not support Nx64 super-rate connections.
This feature is intended to work with video codecs that implement H.222 or BONDING protocol only.

cnfdchtp (configure data channel interface type)
Configures a CDP, CVM, or LDP or LDM DDS port interface type to OCU or DSU. When configuring DDS operations, this command returns an error if executed on a slot with an EIA/TIA-232 back card. It forces a back card slot from EIA/TIA-232 mode to DDS mode if a back card is not installed and there are no connections. Any Y-cable association is deleted in this case. The clocking tracks the DDS port interface type. OCU type interfaces are configured as looped, and DSU type interfaces are configured as normal. The default interface is DSU.
When configuring CDP, CVM, LDP, or LDM operation, this command configures DCE types as normal clocking and DTE types as looped clocking. The default type is DCE. For T1 lines, DS0A on T1 unassigned signaling is configurable. When a connection is not present, voice channels are converted to data channels.

cnfdclk (configure data channel clocking type)
The clock configuration of each channel of a connection determines how the clock will be propagated through the network, and how external equipment should be synchronized.
If clocking is not set correctly, there might be no synchronization, and the connection would operate in a plesiochronous mode. Each data port can be configured independently to act as either DCE or DTE by adjusting the jumper (SDI card) or changing the adapter cable (LDI card) on the data interface card. The effect of the clocking type designated depends on whether each data port is configured as DTE or DCE.
Syntax
cnfdclk <channel> <normal | split | looped>
Parameters
Attributes
These data clocking configurations are possible with the cnfdclk command:
DCE-Configured Data Port: Normal Clocking
When the data port is configured as DCE, selecting a clocking type of n (for normal) results in clocking as illustrated in Figure 3-11. The IGX node, acting as DCE, provides both the transmit and receive data clocks to the user equipment.
Figure 3-11 Normal Clocking on a DCE
DCE-Configured Data Port: Split Clocking
When the data port is configured as DCE, selecting a clocking type of s (for split) results in clocking as illustrated in Figure 3-12. In split clocking, TT may be generated independently of RxC. The maximum data rate for split clocking is 112 Kbps.
Figure 3-12 Split Clocking on a DCE
DCE-Configured Data Port: Looped Clocking
When the data port is configured as DCE, selecting a clocking type of l (for looped) results in clocking as illustrated in Figure 3-13. The Terminal Timing signal, called TT or XTC, is simply RxC looped back from the user equipment. In this configuration, it is important that the two clocks (RxC and TT) be frequency locked. This clocking configuration is supported for all data rates.
Figure 3-13 Looped Clocking on a DCE
DTE-Configured Data Port: Normal Clocking
When the data port is configured as DTE, selecting a clocking type of n (for normal) results in clocking as illustrated in Figure 3-14. The IGX, acting as DTE, receives both the transmit and receive data clocks from the user equipment. When the user equipment is not referenced to the network clock, the maximum data rate for this configuration is 112 Kbps. The two clocks must be frequency-locked for proper operation.
Figure 3-14 Normal Clocking on a DTE
DTE-Configured Data Port: Split Clocking
When the data port is configured as DTE, selecting a clocking type of s (for split) results in the clocking as illustrated in Figure 3-15. When the user equipment is not referenced to the network clock, the maximum data rate for this configuration is 112 Kbps. The two clocks must be frequency-locked for proper operation.
Figure 3-15 Split Clocking on a DTE
DTE Configured Data Port: Looped Clocking
If you specify clocking type of l (looped) when the data port is in DTE mode, the result is the clocking arrangement shown in Figure 3-16. The RxC clock signal is the TT(XTC) signal looped back to the IGX node by the user equipment. The network supports this clocking configuration for all data rates. The restrictions to the data clocking schemes are:
•Except for special cases, isochronous clocking is limited to data rates of 112 Kbps or less. For higher data rates, all clocks must be frequency-locked to the network.
•For any port there must be only one isochronous clock in a direction. Any situation where user equipment provides two clock signals that are not locked is subject to slippage.
•Slippage may also occur in any situation where there are opposing user clocks for a single direction of data.

cnffrcon (configure Frame Relay connection)
Configures bandwidth parameters or enables ForeSight for an individual Frame Relay connection. Because you normally specify bandwidth parameters through the Frame Relay class or by the option of overriding bandwidth parameters through specific arguments for addcon, it is more common to use cnffrcon where you need to customize a single connection's bandwidth parameters.
Be sure the MIR you specify is appropriate. If the MIR is too high, bandwidth is wasted. If it is too low, the connection may drop data. The statistics reports are the best source of information to help you determine the appropriate MIR.
The PIR usually is set to the port speed. You can specify a lower PIR if other constraints on the data generation rate exist. If the PIR you specify is too low, frames are dropped. If it is too high, bandwidth may be wasted unless the network has ForeSight.
The Cmax, VC Q, and ECN Q values should be changed only by knowledgeable users and when tuning data is available to support the determination of appropriate values. These values affect system buffering resources, so any change from the defaults requires caution. Refer to the Cisco WAN Switching System Overview for more details on connection parameters.
If the connection type has ForeSight (FST = y), the result of the last test round-trip delay command (Test RTD) is displayed. Note that this is not the current RTD but the result of the last, user-specified test. High or low connection priority is displayed for both standard Frame Relay connections and ForeSight connections.
The node checks the bandwidth parameters to promote efficient use of network bandwidth. These messages reflect the checks on bandwidth usage:
•Error: Min cannot exceed peak
•Warning: Min exceeds this port's speed.
•Warning: Sum of mins exceeds port's speed.
•Warning: Peak exceeds this port's speed.
Warning messages are informational and do not indicate that the command is failing to execute. Error messages indicate the command is not executing.
When you specify the frp_bw parameters, enter all changes (or unchanged values indicated by an asterisk) on the line. You must specify either a change or a place-holder (*) up to at least the last changed value (after which place-holders are unnecessary). Decide on any changes before starting this command.

cnffrcport (configure Frame Relay port)
Configures the port speed and percent of utilization on the concentrated link of a Port Concentrator Shelf (PCS). This is not a standard command. Primarily, you would use cnffrcport to adjust the rate on the concentrated link due to some unusual system configuration.
Because this command applies to the FRC interface (the concentrated link) rather than the user port for the CPE, the port number and the range of speeds is the same as that of the FRP or FRM card. Thus, the port numbers are 1-4 with rates varying from 56 Kbps through 2 Mbps. During port configuration, a prompt for each parameter appears. To keep the current value of the parameter, press the Return key without typing anything.

Upgrading from Release 9.1 to Release 9.2 When IMA Trunks Exist
When IMA trunks exist in a Release 9.1 network, and you are upgrading from Release 9.1 to 9.2, ensure that the following steps have been performed:
•While the network is running Release 9.1, use the cnffunc command option 15 to disable the Automatic Card Reset after Burnfw for CBI cards option. (Note that this option is enabled by default.) This step is required so that you can burn UXM firmware revision on the flash and delay execution with this new firmware revision, then later reset the card by using the resetcd command. After the UXM at both ends of the trunks is burned with the new firmware revision, you can reset the UXM cards at the same time so that the new ATM Forum-Compliant protocol is invoked at both ends at the same time. If this step is not followed, some nodes may not be reachable if this is an IMA trunk, and it is the only trunk connected to that remote node. Note that if an IMA trunk is not used within the 9.1 network, then you do not need to perform this step.
•Upgrade all UXM cards in the Release 9.1 network with UXM firmware model B.
You are now ready to upgrade the switch software from Release 9.1 to 9.2.
Example (IGX)
Enables automatic card testing after a card failure has been detected.

cnffwswinit (configure FW/SW download initiator IP address)
Specifies the IP address of the machine used to initiate a firmware or software download. With Release 9.3.30 and higher, the cnffwswinit command is also used to specify the IP address of the network server used to initiate the configuration save and restore operation using a TFTP Start file or SNMP interface.
This is a safety measure to prevent downloads from being started anywhere in the network. You must have access to a node, and use the cnffwswinit command to set the IP address before a download will be accepted from that address.

cnfict (configure interface control template)
Sets the interface control template signals. The signals that can be set by using cnfict depend on the type of back card used and whether the hardware is configured for DCE or DTE. On an IGX node, the applicable front cards are the LDM, HDM, FRM, and CVM (for data). Each data channel has a default interface control template for its active, conditioned, and looped near and far states. Use the cnfict command is used to individually configure each interface control lead in each template.
When Y-cable redundancy is in effect, the control template configuration for the data channels terminating at the primary slot is also applied to the data channels of the secondary slot. Any configuration information for the secondary slot is ignored.
Note The cnfict command is not valid for V.11 and X.21 interfaces. For FRP V.35 and Port Concentrator V.35 and V.28 interfaces, only the active template is usable, and you can configure the leads to On or Off.

Configurable Lead Names and Functions
Table 3-26 shows the configurable leads and the equivalence between EIA/TIA-232C, EIA/TIA-232D, EIA/TIA-449, V.35, and X.21 interfaces. The leads are configurable for each type of data interface supported by the IGX node. An IGX treats leads impartially for non-interleaved connections.
The entries under the IGX Name column indicate the abbreviations to use when specifying input or output leads on the command line. A node treats leads impartially for non-interleaved connections. Any signal received on an EIA pin at one end may be transmitted to any pin at the other end, up to the maximum of 12 EIA leads on any interface type. For interleaved EIA connections, refer to the Fast EIA column. The column shows which leads are carried in the interleaved bytes of the data packets. All remaining leads are carried in standard control lead packets.

Note that pins 11 and 23 on an EIA/TIA-232 port are bidirectional, and their default direction is input. See the cnfcldir command for information on changing the direction of these pins. The cpyict command can be used to copy an interface control template from one data channel to another. You can then edit it by using the cnfict command. The dspbob command displays the state of leads at specified intervals.

cnflan (configure LAN)
Configures node communication parameters, to enable the node to communicate with a Cisco WAN Manager terminal over an Ethernet LAN using TCP/IP protocol. The parameters all contain address information about the Ethernet TCP/IP network that connects the Cisco WAN Manager station to an IGX or BPX node. The values must conform to those of the network. The network administrator can supply the parameters.
With Release 9.3.30, the cnflan command supports the first phase of the Automatic Routing Management to PNNI migration. When the XLMI protocol and the LMI Neighbor Discovery feature are enabled (using the advertise interface information parameter from the cnfport command) and the LAN IP is the selected Management IP address, the new LAN IP address is sent to the BXM card whenever the LAN IP address is changed. The cnfnodeparm command is used to select the Management IP address.

cnfln (configure line)
Configures a line to be compatible with the device to which it connects. The cnfln command applies to voice, data, Frame Relay, ATM (including IMA lines). The cnfcln command is an alias for cnfln.
Because of the variety of line types and characteristics, separate parameters sections are included in this command description to define the parameters for specific line types. The system automatically presents the correct options on the command line for each line type. If a parameter is not applicable to a card type, the system displays the parameter in half-tone or the parameter value field with dashed lines.
Note In Release 9.3.20 and higher, the cnfln command is not used to configure the VC Shaping parameter on IGX ATM ports. You must use the cnfport command to configure VC Shaping. This change applies to all ATM ports in the IGX, that is, ports on the UXM and URM. Refer to the cnfport command for more information specific to ATM port configuration.
Syntax
cnfln <line> <parameters>
Syntax for IMA
cnfln <slot>.<primary link>
Parameters (IGX Voice, Data, Frame Relay Lines)
The following graphic illustrates the loop clock parameter, described in the parameter table that follows.
Figure 3-17 Loop Clock Illustration
Parameters (BPX ATM Line)
Parameters (IGX ATM UXM Line)
Parameters (IGX IMA UXM Lines)
Parameter Descriptionslot.line
Specifies which line on which slot to configure.
Line DSO-Map
Line DSO mapping.
IMA Group Members
Specifies the line numbers of the individual links composing the IMA group.
Retained Links
The minimum number of links in the IMA group that must be active in order for the IMA line to operate. For an IMA line, you can add or delete links in an IMA group, or specify the number of retained links for an IMA configuration. If the number of links fails and falls below the retained link number specified, the IMA line fails.
By default, the number of retained links is the same as the number of lines grouped together when the IMA group is created. For example, the command "upln 3.1-4" results in 4 lines in an IMA group with 4 retained links. If one link fails, the IMA line fails. Using the cnfln command, you can change the Retained Links parameter to a lesser number, for example, 3. Therefore, if one of the lines fails, the IMA line remains active.
IMA Protocol Option
Specify one of the following:
Enable-to enable the IMA protocol on a line
Disable-to disable the IMA protocol on a lineNote: Changing the protocol option on an active line results in port failure. The user should always make sure that the IMA line is configured the same as the CPE.
IMA Max. Diff. Dly.
Specify a value. Range: 0-200 msec. Default: 200 msec. Defines the maximum time that one T1 or E1 link can be delayed with respect to another T1 or E1 link in the IMA line or trunk bundle. If the delay becomes too great, the proper reassembly of IMA frames will not occur, causing traffic errors. There is limited storage capacity in this buffer, therefore this parameter establishes the maximum differential delay which will be tolerated. Accurately specifying the delay results in optimum performance due to reduced buffer time; overspecifying the delay results in poor performance due to unnecessary cell waits in the buffer. Refer to Figure 3-18.
IMA Clock Mode:
The clock mode is Common Transmit Clock (CTC).
Loop Clock
Enables the transmit and receive control leads to use the same clock. Specify Yes or No. Default: No.
Line Coding
Configures T1 and E1 coding. Default values per line type are:
E1-HDB3
T1-ZCS
T1-(UFM T1), B8ZS
J1-HDB3
E3-HDB3
T3-B8ZS
OC3-N/A
Possible line coding values for each line type are:
E1-HDB3- not configurable
T1-ZCS, B8ZS, AMI
J1-HDB3- not configurable
E3-HDB3-not configurable
T3-B8ZS-not configurable
OC3-N/A
Line CRC
Enables CRC-4 detection for E1 lines. Use either Y or N. This parameter defaults to "Y" when the line is upped.
Line recv impedance
For E1, a parameter in the range 1-7.
1 is 75 ohm impedance, unbalanced
2 is 75 ohm impedance, unbalanced
3 is 20 ohm impedance, balanced
4 is 0-133 ft impedance, ABAM cable
5 is 133-266 ft impedance, ABAM cable
6 is 266-399 ft impedance, ABAM cable
7 is 399-533 ft, ABAM cable
Idle Code
Hex data placed in unused payload of cells
Range: 0 - FF (hex)
Default: 7FHCS Masking
Masking of cell header checksum to disable error checking. Specify either Yes or No. Default: Yes.
Payload Scramble
Whether or not to scramble (randomize) the cell payload data. Specify either Yes or No. Default: No
Note: for E3, this must always be set to Yes.

cnflnalm (configure line alarm)
Sets the trunk and line alarm values for failures that are statistical in nature. Statistical alarms are declared by the switch software when cards supporting these trunks or lines report too many errors. The switch declares an alarm if the detected error rate equals the cnflnalm parameter error rate for the period of time designated by the alarm time parameter. Error rates that exceed the specified error rate cause an alarm in a proportionately shorter period of time. An alarm is cleared when the error rate remains below the rate specified by error rate for a period of time designated by the clear time.
You can configure the thresholds for alarms caused by the collection of statistics but not for the alarms caused by a network failure. For example, you can configure the threshold for an alarm caused by a collection of bipolar errors, but you cannot configure an alarm caused by a card failure.
Six parameters exist for each failure type—three for minor alarms and three for major alarms. When configuring any item for a minor or major alarm, you must enter a value. You can enter a new value or enter the current value.
The tables show for each failure type, the alarm classes, the possible error rate options, and default alarm times and clear times.

cnflnparm (configure ATM line card parameters)
Configures several parameters for ATM lines originating on the BPX or IGX nodes. The cnflnparm command is quite similar to the cnfln command.
This command configures the circuit line alarm integration times in milliseconds for Red and Yellow circuit line alarms. You should set them to correspond to the local carrier's alarm integration times. The cnflnparm range for each of these parameters is 60-3932100 ms. Carrier integration times are typically 800 ms-1500 ms for Red Alarm and 1500-3000 ms for Yellow Alarm.
You can also set the queue depth for the two queues associated with the ASI-0 card, the constant bit rate (CBR) queue and the Variable Bit Rate (VBR) queue. The queue depths may be increased to
16,000 bytes per queue.Syntax

cnflnpass (configure line pass-through)
Configures a pair of ports so that unprocessed channels go from a primary UVM to a secondary UVM. The cnflnpass command primarily applies to channels that use LDCELP or G.729 CACELP (although pass-through is possible on any type of connection except t-type or td-type). For a description of pass-through, refer to the UVM description in the Cisco IGX Reference.
To return ports to the non-passing configuration, execute cnflnpass with a 0 as the second argument.
Syntax
To configure pass-through, enter:
cnflnpass <primary line> <secondary line>To remove pass-through from the primary and secondary lines, enter:

cnflnsigparm (configure line signaling parameters)
Configures the line signaling parameters associated with a line for the CVM and UVM voice cards.
The CVM and UVM Heartbeat parameter (option 1) is the rate, in seconds, at which the card sends a signaling (ABCD bits) state update to the other end of the connection, even when there is no change in the state of the signaling bits. This is done because signaling packets are time-stamped data packets, and there is a small chance that a signaling packet might be discarded somewhere in the network. This recovery mechanism ensures that on-hook and off-hook notifications are not lost. Increasing this interval will probably have no impact as long as none of the normal signaling time-stamped data packets are being discarded in the network.
In Release 9.2 and higher, the CVM and UVM cards are supported. The CIP and CDP cards are not supported.

cnflnstats (configure line statistics collection)
Configures statistics collection for a line. Primarily, cnflnstats is a debug tool (older alias: cnfclnstats). It lets you customize statistics collected on each line. Table 3-26 lists the statistics for FastPacket-based cards with T1 or E1 lines. For other available parameters, refer to the actual screens on a node. The examples show available statistics for a UXM port and an ASI-155 port.
Not all statistic types are available for all lines. Valid statistics appear in full brightness while unavailable types appear dimmed.
Bipolar violations are not generally accumulated on E1 trunk and circuit lines. They are accumulated only on T1 lines connected to Frame Relay ports.

cnfmode (configure mode)
Selects a mode of the card for a UFM-U back card. The mode of a card is combination of maximum port speeds and for specific port numbers. Table 3-27 lists the maximum port speeds and active ports for each mode. The cnfmode command lets you select 1 of 27 modes for either a UFI-12V.35 back card or a UFI-12X.21 back card. For a UFI-4HSSI back card, three modes are available.
To specify the actual speed of an individual port, use the command cnfport. The IGX documentation describes the application of the modes and the sequence of execution of these commands.
Note The cnfmode and cnfufmumode commands are the same command.

cnfmxbutil (configure muxbus utilization)
Configures the Muxbus or cell bus utilization factor for each FRP or FRM, respectively.
Use the cnfmxbutil command to configure the Muxbus or cell bus utilization factor for each FRP or FRM in the node on a slot-by-slot basis. (System software automatically allocates a certain amount of bandwidth for each FRP or FRM in a node. Since the maximum data rate for an FRP or FRM is 2 Mbps, this bandwidth is also the maximum amount of the bus reserved for an FRP or FRM.)
In many applications, each of the four FRP or FRM ports is configured for a large number of 56 or
64 Kbps connections. System software totals the bandwidth required for all the connections, multiplies the total by 121% to reserve extra bandwidth for overhead, then subtracts this amount from the total available bus bandwidth.However, statistically full utilization is not often required on ports with a large number of connections, so the reserved bus bandwidth may be further reduced. In a node with a T3 or E3 ATM trunk card, much of the bus bandwidth may be assigned to the ATM trunk, so you should exercise caution when allocating the remaining bus bandwidth.
Syntax
cnfmxbutil <slot number> <percentage>
Parameters
Parameter Description<slot number>
Specifies the slot number of the associated FRP card.
<percentage>
Specifies the percent of Muxbus or cell bus bandwidth to allocate.
Attributes
Example
Configure Muxbus Utilization. The screen displays "N/A" for a slot where no FRP or FRM exists. Once the slot is selected, the system displays the message "Enter Utilization Factor." The range is 1-250%. The default is 121%. The extra 21% for the default is for the overhead for encapsulating the Frame Relay frame into the FastPackets or ATM cells.

cnfname (configure node name)
Specifies the name by which a node is known within the network. It may be changed at any time. The new node name is automatically distributed to the other nodes in the network.
Node names are case sensitive. For example, an upper-case "A" is not considered to be the same as a lower-case "a". Duplicate names are not allowed in the same network.
Node names may be configured from within a job sequence. If the node name is changed and the corresponding name in the job is not changed, the job will not function properly.
In these situations, the cnfname command cannot be executed:
•Another node is attempting to change the network topology by adding or deleting a trunk.
•Another node is notifying all nodes that it has been renamed. Another node is currently adding or deleting a channel connection in the network with the addcon or delcon commands.
•There is an unreachable node in the network.
•The name chosen is already being used for another node in the network.

cnfnodeparm (configure node parameter)
Sets a variety of general parameters for a node in the network.
The defaults for the network parameters are selected by Cisco engineering to operate under normal conditions. With few exceptions, you should change them only with the guidance of the Cisco TAC.
With the first phase of the Automatic Routing Management to PNNI migration introduced in Release 9.3.30, the BXM interface card supports the Extended LMI (XLMI) protocol. This protocol enables the exchange of topology information between the adjacent BXM and AXSM over the AR-PNNI link. With Release 9.3.30, use the cnfnodeparm BPX parameter option 56 to configure the XLMI Management IP address as LAN IP or Network IP address. Whenever the choice of Management IP address is changed, the new Management IP address is sent to the BXM.
With Release 9.3.30, use the cnflan and cnfnwip commands to configure IP addresses. Use the cnfport command to enable XLMI protocol and the LMI Neighbor Discovery feature (using the advertise interface information parameter). Use the dspnebdisc command to display the AXSM's neighbor information discovered by the BPX via the LMI Neighbor Discovery procedure.

cnfnwip (configure network IP address)
Configures an IP address and subnet mask for the node. The network IP address and subnet mask support statistics collection for Cisco WAN Manager. The cnfnwip command defines the IP address the system uses to pass messages between Cisco WAN Manager and the node. The Statistics Master process in Cisco WAN Manager Network collects statistics. The Statistics Manager requests and receives statistics using TFTP Get and Put messages. These TFTP messages pass between the node and the Statistics Master using IP Relay. (See the cnfstatmast description for details on setting the Statistics Master address.)
The cnfnwip command supports the first phase of the Automatic Routing Management to PNNI migration. When the XLMI protocol and LMI Neighbor Discovery feature are enabled and the network IP is the selected Management IP address, the new network IP address is sent to the BXM card whenever the network IP address is changed.
Syntax
cnfnwip <IPAddr> <IPSubnetMask>
Parameters
Parameter Description<IPAddr>
IP address of the node: the format is nnn.nnn.nnn.nnn, where nnn can be 1-255
<IPSubnetMask>
subnet mask: the format is nnn.nnn.nnn.nnn
Attributes
Example
cnfnwip 199.35.96.217 255.255.255.0
where:
199.35.96.217 is the IP address, and 255.255.255.0 is the subnet mask.

cnfoamseg (configure connection OAM segment status)
Configures the segment status of an Extended PVC (XPVC) segment in a hybrid Automatic Routing Management-PNNI network. Using cnfoamseg for PVC is only applicable for ENNI/EUNI ports. To change the connection segment type for PVCs terminating on ENNI/EUNI ports has no impact to end-to-end OAM cells, such as AIS.
With Release 9.3.30, the BPX 8600 supports an XPVC that spans over an AR-PNNI, or AR-PNNI-AR, hybrid network. The Cisco WAN Manager (CWM) is used to add, modify, and delete XPVCs (using the SNMP Service Agent proxy along with provided CWM-XPVC-CLI scripting capability). The CWM is also used to display XPVC connection details and monitor XPVC status.
The AR BXM and PNNI AXSM interface cards allow Enhanced UNI (EUNI) and Enhanced NNI (ENNI) port types that support XPVC segments. XPVC segments terminating on EUNI/ENNI ports are automatically programmed as "non-segment" endpoints. Non-segment endpoints do not loop back OAM segment loopback cells. With non-segment endpoints, OAM loopback cells are passed through to the adjacent network. Consequently, the CWM test procedures, such as test delay, cannot identify a faulty XPVC segment. When end-to-end XPVC testing fails, the faulty AR or PNNI network and faulty XPVC segment must be identified.
You use the cnfoamseg command to change the segment status of an XPVC segment from "non-segment" to "segment". When the XPVC segment status is "segment", OAM segment loopback cells are looped back at the terminating EUNI/ENNI endpoint. This allows CWM test procedures to be executed on each XPVC segment to isolate a fault. The command cnfoamseg does have SNMP support.
The CWM is notified when the XPVC segment status is changed. The XPVC segment status is persistent. The status is retained for node rebuild and card reset. The secondary BXM card in a Y-redundant pair retains the segment status.
Use the CWM interface to determine fault isolation instead of trying to do this from the CLI. After a fault has been isolated, use the cnfoamseg command to reset the XPVC segment status as "non-segment" for normal operation in the AR-PNNI hybrid network. Use the dspoamseg command to display the current segment status of an XPVC segment.

cnfphyslnstats (configure physical line statistics)
Configures parameters for circuit line statistics collection on a UXM card. This is a debug command that applies to physical lines on a UXM card using Inverse Multiplexing Over ATM (IMA)—a logical trunk or logical line configuration. It primarily applies to debugging and not standard network operation.
Use the cnfphyslnstats command to customize statistics collection on each physical line. To see the statistics available for each type of interface, refer to the actual screens for each interface, as in the subsequent examples.
Since Release 9.2, for virtual trunking, physical line statistics apply to each physical port. In the case of IMA trunks, the physical line statistics are tallied separately for each T1 port.
IMA physical line alarms are a special case. Each IMA trunk or line has a configurable number of retained links. If the number of non-alarmed lines is less than the number of retained links, the logical trunks on the IMA trunk or line are placed into major alarm.
For example, consider IMA virtual trunks 4.5-8.2 and 4.5-8.7, with the number of retained links on 4.5-8 configured to 2. If 4.5 and 4.6 go into LOS (loss of signal), physical line alarms are generated for these two physical lines. The logical trunks 4.5-8.2 do not go into alarm because the two retained links are still healthy. In this situation, the bandwidth on the logical trunks is adjusted downward to prevent cell drops, and the connections on those trunks are rerouted. If a third line goes into alarm, the logical trunks are then failed.
IMA Physical Line Statistics
The cnfphyslnstats command lets you configure the following additional physical line statistics (which support the ATM Forum-compliant Version 1.0 IMA protocol). A summary and description of these statistics follows in Table 3-28.

cnfport (configure Frame Relay port)
Configures the parameters of a Frame Relay port. The cnfport command applies to the UFM/UFI, FRP/FRI, FRM/FRI, and FRM-2/FRP-2. (Note that a command also exists for the concentrated link between the PCS and FRM-2 or FRP-2: cnffrcport.)
During port configuration, a prompt for each parameter appears. To keep the current value of the parameter, press the Return key without typing any characters. When a parameter is not configurable for an application, the parameter appears shaded or with dashed lines.
Starting with Release 9.3.10, the ELMI (Enhanced Local Management Interface) Neighbor Discovery feature is supported on ports on the UFM. This feature serves the same purpose as the ILMI Neighbor Discovery feature. For additional information see the "ELMI Neighbor Discovery for UFM" section.
You can mix the data rate for each of the ports if the total for all ports does not exceed the maximum composite data rate that the card set supports. Table 3-29 shows the supported data rates for individual T1 and E1 lines.
Table 3-30 shows the available data rates on a single, PCS user-port. For the FRP-2 and FRM-2 cards, the maximum composite data rate over the 44 logical user-ports is 1.792 Mbps.

For a PCS, some additional rules for assigning data rates to the 44 ports apply:
•No single user-port should have a speed greater than 384 Kbps.
•The total for each group of 11 ports should not exceed 448Kbps. The software allows higher rates, but the system may drop data if user-equipment passes data above the aggregate total of 448 Kbps.
•The port numbers for the 11-port groups are 1-11, 12-22, 23-33, and 34-44.

ELMI Neighbor Discovery for UFM
Starting with Release 9.3.10, Enhanced Local Management Interface (ELMI) provides a protocol to monitor the status of permanent virtual connections between two Cisco communication devices. Through ELMI for example, the network management system (NMS) becomes aware of the existing connectivity between an IGX 8400 switch and a Cisco IOS router running ATM or Frame Relay.
The enhanced version of ELMI on IOS is called ELMI-AR (Address Resolution). Note that, since IGX switches mainly are connected to routers that run IOS, you must implement the same protocol on IOS, too.
The ELMI protocol enhancements for the UFM serves the same purpose as the ILMI enhancements for the UXM, and implements similar mechanisms to enable Neighbor Discovery. While ILMI Neighbor Discovery works with ATM links, ELMI Neighbor Discovery works with Frame Relay links. ELMI Neighbor Discovery is a Cisco standard, while ILMI is based on the standard ILMI protocol.
Use parameter option 53 from the cnfnodeparm command to configure the ILMI Management IP address. The Management IP address is used by the NMS application to access the IGX or the ATM device. Depending upon your network set up, you can configure the IGX to send either the LAN IP address or Network IP address as part of the neighbor information exchange with the attached ATM device. Enter 0 for LAN IP address, or 1 for Network IP address. The IGX switch default is the network IP address.
Once the parameter is set in cnfnodeparm, enable Neighbor Discovery using the cnfport command. Set the Advertise Interface parameter to "Yes" to enable the feature.
Signaling Protocol Timers
This section introduces the implementation of two signaling timers and related parameters you can specify through the cnfport command.
Periodically, devices use signaling to request the status of other, connected devices or networks. The signaling can be a simple confirmation of the other device's existence or more detailed information, such as the DLCIs, bandwidth, and state of all PVCs. The signaling described here occurs between:
•The user-equipment and a Frame Relay port across the user-to-network interface (UNI)
•Frame Relay ports in the network across the network-to-network interface (NNI)
Periodically, Frame Relay ports within the network transmit a Status Enquiry and wait for a Status response. These exchanges occur across the UNI and the NNI. At the UNI, the user-equipment periodically sends a series of Status Enquiries and awaits a Status response for each enquiry. At the NNI of any network, a Frame Relay port can generate Status Enquiries and, at alternate times, receive Status Enquiries. In this way, the signaling between networks mirror each other. ( Figure 3-19 shows the three possible exchanges.) The timers for Status Enquiry and Status Response and other, related parameters are the:
•Link integrity timer—the time period between each Status Enquiry that either the user-equipment or a Frame Relay port in the network generates
•Polling verification timer—a time period in which a Frame Relay port waits for a Status Response to a Status Enquiry that the port generated
•Error threshold—the number of missing or erroneous events that triggers a Port Communication Failure
•Monitored events count—the number of events in a polling cycle
•Full status polling cycle—a polling cycle in which the port that has sent the Status Enquiry waits for detailed status information
In the preceding list, an event is either a Status Enquiry or a Status Response. The meaning of the event depends on whether the link integrity timer or the polling verification timer is waiting for the event. The link integrity timer waits for Status Responses. The polling verification timer waits for Status Enquiries.
Most Status Enquiries contain only a sequence number. After sending these simple Status Enquiries, the polling device checks for the sequence number. Periodically, a full status polling cycle takes place, in which the polling device waits for all applicable information, such as the status of all connections that cross the NNI. For signaling across the UNI, the Frame Relay Forum has recommended a full status polling cycle at every sixth polling cycle. The Frame Relay Forum has not recommended a frequency for the NNI. The cnfport command lets you select a frequency in the range of once every 1-10 polling cycles.
The Frame Relay port or user-device counts a user-specified number of errors out of a user-specified number of attempts before it signals a Port Communication Failure. These parameters are the error threshold and the monitored events count, respectively. The defaults for these parameters are 3 and 4, respectively. To use the defaults in an example: if 3 out of 4 events are either missing or erroneous within the specified time period, the port signals a Port Communication Failure (a minor alarm).
An event has a user-specified amount of time to arrive. The allowed time period for the arrival of a valid event is the number of seconds you assign to a timer. If an enquiry or response is missing or bad within the timer value, the event is failed. Again, using all default values in an example: if the polling verification timer is 15 seconds and no Status Enquiry arrives within that time, the port records a missing Status Enquiry. If no Status Enquiry arrives during the next two 15-second periods, the port signals a Port Communication Failure. In the UNI example in the figure, the third Status Enquiry does not arrive. Note that each time a Status Enquiry arrives, the polling verification timer restarts counting at 0 seconds rather than waiting until the specified number of seconds has elapsed.
Whether the port is on a UNI or NNI, the polling verification timer setting must be longer than the link integrity timer. (Refer to the cnfport parameters table for values.) You cannot set the link integrity timer for the user-equipment with cnfport. Usually, the link integrity timer on user-equipment is 10 seconds, which you can verify by executing dspportstats and counting the number of seconds between statistical updates. On the NNI, you can set both timers (they use either Annex A or Annex D).

The rules for assigning data rates to the four ports when using the 1 Mbps FRI are:
•If you assign a data rate of 672 Kbps or higher on any port, you cannot use any other port.
•If you assign a data rate of between 384 Kbps and 512 Kbps to any port, you can specify a second port with an available data rate of 512 Kbps or less.
•If you assign a data rate of 336 Kbps to any port, you can specify two other ports for any available data rates of 336 Kbps or less.
If the data rate of any port does not exceed 256 Kbps, you can specify all four ports with any available data rates of 256 Kbps or less.
cnfport (configure ATM port)
Configures the parameters of an ATM port on the IGX or BPX. The command is used to:
•configure an ATM port on the UXM in the IGX.
•configure the internal ATM port on the Universal Router Module (URM) in the IGX.
•configure an ATM port on the ASI and BXM cards in the BPX.
During port configuration, a prompt for each parameter appears. To keep the current value of the parameter, press the Return key without typing any characters. When a parameter is not configurable for an application, the parameter appears shaded or with dashed lines.
For additional information see the "Traffic Shaping on the UXM and URM" section, the "Traffic Shaping on the BXM" section, and the "Virtual Ports" section.
The cnfport command supports the Universal Router Module (URM) on the IGX 8400. The URM provides IOS-based voice support and basic routing functions. It consists of an embedded UXM with one internal ATM port and an embedded IOS-based router. The external interface type of the URM ATM port is defined as internal. The internal interface is a logical internal ATM port. The internal ATM port speed is equivalent to an OC-3 port. The default port configuration is the same as the default configuration for a UXM port. The port type is UNI with no protocol. The port cannot be configured as NNI, and the protocol cannot be configured as LMI, as the embedded router does not support the LMI protocol. Switch software reserves the VPI.VCI pair 0.1023 for the internal IPC mechanism used for UXM to router communication.
In Release 9.3.30, the cnfport command supports phase one of the Automatic Routing Management to PNNI migration. You use the cnfport command to set the BXM port type as Enhanced UNI (EUNI) or Enhanced NNI (ENNI) and to enable the Extended LMI (XLMI) protocol and LMI Neighbor Discovery feature (using the advertise interface information parameter). This port configuration is required to support the Extended PVC (XPVC) segment that links the BPX to the adjacent MGX in the hybrid AR-PNNI, or AR-PNNI-AR, network. See the "Automatic Routing Management to PNNI Migration" section for more information.
Parameters
Parameter Descriptionslot.port[.vport]
Specifies the card slot, physical, and optional virtual port number (BXM only). At this time, virtual ports are not available for ASI, UXM, or URM cards.
port type
Specifies whether the cell header format is NNI, UNI, EUNI, or ENNI. UNI is the default. NNI cannot be configured on the URM embedded UXM port.
Specifies the ATM cell header format. Values are:
•UNI (default value)
•NNI
Additional values to support Automatic Routing Management-PNNI links in a hybrid network, BPX only:
•Extended UNI (EUNI)
•Extended NNI (ENNI)
With EUNI/ENNI port types, all new connections are programmed as "non-segment". These non-segment connections do not terminate OAM segment loopback cells.
EUNI/ENNI port configuration is allowed only when the XLMI protocol is enabled on the BXM port. EUNI/ENNI port types cannot be configured on ports with existing connections. Only the following combinations are supported:
•UNI to EUNI
•NNI to ENNI
ENNI/EUNI is also support for the BXM-E.
If the port type is UNI and the port type required is ENNI, you must first provision the port as NNI, then as ENNI.
Note Release 9.3.30 Switch Software disables FCES and Policing on the PVC endpoint, which is terminating on the XLMI link.
metro data cell header
Specifies whether the metro data cell header type is used (ASI-T3 cards only).
VPI Range
BPX only: VPI Range is configurable on Virtual Ports and defaults to 0-255/4095 for Physical Ports (based on UNI/NNI type). The VPI Range cannot overlap with any other VPI Range on the physical interface.
The range for EUNI port types is the same as for UNI (0-255). The range for ENNI port types is the same as for NNI (0-4095).
Bandwidth
BPX only: Bandwidth is configurable on all ports. For Virtual Ports, this parameter specifies the maximum bandwidth available for a Virtual Port. Each port has this parameter configurable. Connections within the Virtual Port may overbook the bandwidth if CAC Override is enabled, but the actual throughput will never be allowed to exceed the Virtual Port bandwidth.
Note Changing the line framing for BXM-T3 cards from PLCP to HEC no longer automatically changes the port's bandwidth to the new maximum. It merely raises the upper limit for the port's bandwidth. After changing the framing, you must use cnfport to increase the port's bandwidth, and cnfrsrc to increase the port's Automatic Routing Management bandwidth (PVC Max Bandwidth).
CAC Reserve
BPX only: CAC Reserve is configurable on all ports, but only valid if CAC Override is disabled. This parameter specifies the amount of Automatic Routing Management Port Bandwidth not available for booking by connections if CAC Override is disabled. If CAC Override is enabled, overbooking is permitted. The purpose of this parameter is to reserve some bandwidth to handle bursts of traffic without cell discards.
shift h | n
Specifies whether a one-byte shift on the HCF field of the cell header occurs. Changing the HCF field for a physical port will affect all virtual ports supported on the physical port.
The choice of H (shift) or N (no shift) depends on whether the ATM cloud includes non-Cisco WAN Switching nodes and whether virtual trunking is in operation:
•You typically select H (the default, or shift on) if the cloud includes non-Cisco WAN Switching nodes or if only a physical trunk is configured for the ASI port.
•You typically select N (shift off) if virtual trunks are configured and the ATM cloud consists of Cisco WAN Switching nodes only.
For BPX or IGX ports performing virtual trunking within an ATM cloud to external Cisco equipment, ports should be configured to shift on (that is, shift H) for BNI cards; BXM ports should typically be configured to shift off (shift N).
Note For UXM cards, you cannot configure the Shift parameter—the Shift setting is always N, or shift off.
For example, if the public ATM cloud consists of BPX nodes, the access points to the cloud might be ASI ATM UNI ports. Because the cells transmitted to the ASI trunk interface are coming from a Cisco device, for example, a BNI card, the 16 VCI bits have already been left-shifted by four (4) bits and contain 12 bits of VCI information and four (4) bits of ForeSight information. Therefore, the ASI cards at either end of the cloud should be configured to not shift (that is, shift off). In this case, you would configure shift N on the ASI port.
If the ATM cloud consists of non-Cisco nodes, then the 12 VCI bits + 4 ForeSight bits in the cells coming from the BNI card in the BPX are then passed through untouched as 16 VCI bits. Because it is a non-Cisco network, the ForeSight bits are ignored.
Make sure that you set the HCF field correctly for your network configuration before you add connections. For example, if you are acting as a service provider, and one of your customers wants to configure virtual trunking through the network, if your ports have been previously configured with the incorrect HCF shift field setting, you may need to go back and delete all the connections from each port, configure the port, and add the connections again.
Below are guidelines on how to set the Shift parameter when using BNI virtual trunking through a cloud of Cisco equipment using BXMs, and a cloud using ASIs and BNIs. Also shown is how to set the Shift parameter when using either BXM or UXM virtual trunking through a cloud of Cisco equipment (BXM cards), and a cloud of ASIs and BNIs.
%util
Enables/disables percent utilization. This parameter supports ATM VBR/ABR fairness for ASI terminated connections and applies to only VBR and ABR connections. To change the %util status of a port, no connections can be currently terminating on the port. Therefore, if connections terminate on the port, they must be deleted before cnfport execution then re-added after execution of cnfport.
The port queue bandwidth with %util feature disabled is:
•For ABR connections Port Queue BW = sum (MCR)
•For VBR connections Port Queue BW = sum (PCR)
•For CBR connections Port Queue BW = sum (PCR)
When the %util feature is enabled, the port queue bandwidth is calculated for ABR and VBR connections as follows: for ABR connections, the port queue bandwidth is the sum of a percentage of the MCRs for the connections terminating on the port; for VBR connections, the port queue bandwidth is the sum of a percentage of the PCRs for connections terminating on the port. The feature is not applied to CBR connections.
In summary, the port queue bandwidth with feature %util enabled is:
•For ABR connections Port Queue BW = sum (MCR * %util)
•For VBR connections Port Queue BW = sum (PCR * %util)
•For CBR connections Port Queue BW = sum (PCR)
For virtual ports, parameter can be set to Enable or Disable and is only pertinent to the specific virtual port.
CAC Override
Controls the allocation of bandwidth on a port.
If enabled, connections are allowed to be added to a port even if the bandwidth requirements exceed the port capacity.
If disabled, the bandwidth requirements of all connections on the port will not exceed the port capacity.
protocol
Specifies the use of either an LMI protocol, an ILMI protocol, an IXLMI protocol (BXM only) or no specified protocol. No specified protocol is the default.
LMI cannot be configured on the URM.
When the protocol is enabled on a virtual port, ILMI processing is done only on the BXM card. You cannot configure the protocol to run on the controller card (BCC) with virtual ports. The ILMI configuration performed on one virtual port applies to all virtual ports on the same physical interface.
The ILMI Neighbor Discovery feature on a BXM interface with virtual ports is supported on BPX but not yet supported by CWM.
Note The cnfport command prevents disabling ILMI protocol on a port interface if a VSI ILMI session is active on a VSI partition of the port interface.
Values for protocol are one of the following:
N-(NONE)
L-(LMI)
I-(ILMI)
XL-(XLMI)
The default LMI/XLMI parameters are:
•VPI for LMI/XLMI connection: 0 (3 if the protocol is XLMI)
•VCI for LMI/XLMI connection: 31
•LMI Polling Enable?: N
•LMI Status Enquiry Timer (T393): 10 seconds

Note In order to enable the migration topology discovery feature, set:
•Protocol to XL
•VPI to 3
•VCI to 31
•Polling to Yes
•Protocol on the Card to Yes
•Advertise Interface Information to Yes

Note An IMA configuration will display the same protocol values as shown above.
Protocol by Card
For the BPX, defines the card that runs the LMI/ILMI protocol. The LMI/ILMI protocol can run on either the interface card (BXM) or the controller card. Values are Y/N. The default is N.
•Y - selects the interface card to run the LMI/ILMI protocol
•N - selects the controller card to run the LMI/ILMI protocol
This parameter is supported on BXM interfaces configured with virtual ports. The setting of this parameter on one virtual port applies to all virtual ports on the same physical interface.
This parameter is automatically defaulted to Y when the XLMI protocol is selected. The XLMI protocol runs only on the BXM interface card.
Note For a BXM interface configured with virtual ports, the ILMI protocol runs only on the card. The protocol is blocked from running on the BCC.
Protocol run on the card
For the IGX, defines the card that runs the ILMI protocol. This must be set to Y for XLMI provisioning support. The ILMI protocol can run on the interface card (UXM and URM) or the controller card. Values are Y/N. The default is Y.
•Y - selects the interface card to run the ILMI protocol
•N - selects the controller card to run the ILMI protocol
This parameter is applicable only when the ILMI protocol is selected and the card supports the LMI/ILMI protocol.
Note For the URM, the ILMI protocol runs only on the card. The protocol is blocked from running on the NPM.
Advertise Interface Information
The advertise interface information parameter defines whether the interface is authorized to advertise its interface information. Values are Y/N. The default is Y.
•Y - the switch sends its topology information (such as, the switch management IP address and Interface Name) to its neighbor.
•N - the switch does NOT send its topology information to its neighbor. Instead, the switch sends 0.0.0.0 as the management IP address and a NULL string as Interface Name to the neighbor
The user is prompted for this parameter when Protocol is ILMI or XLMI, Protocol by Card (BPX) or Protocol run on the card (IGX) is set to Y, and the interface card supports the Neighbor Discovery feature.
The setting of this parameter does not affect the incoming neighbor's topology information. If the neighbor sends its topology information to the switch, the switch processes and stores the information. The neighbor's topology information is displayed using the dspnebdisc command.
Note The ILMI Neighbor Discover feature on a BXM interface with virtual ports is supported on the BPX but not yet supported on CWM.
ILMI Reset Flag
BXM only. This indicates whether the ILMI session is to be reset when a PNNI controller is added. The default is Yes.
VC Shaping
IGX ports only. Specify one of the following:
Yes—Applies egress traffic shaping to each VC.
No—Does not apply egress traffic shaping to each VC.
In previous releases the cnfln command was used to enable or disable VC shaping on ATM ports in the IGX. The cnfport command is now used to configure VC shaping. This change applies to all ATM ports in the IGX, i.e., UXM and URM ports.
Refer to Traffic Shaping on the UXM and URM and Traffic Shaping on the BXM for more information about this topic.
F4-F5 Mapping
BXM only. Enables/disables the F4 to F5 Mapping feature. Values are "Y" to enable, "N" to disable. The default value is "N".
You can enable the feature only when the number of required F4-F5 channels are available. The cnfport and dspport commands display the number of F4-F5 channels on the port. If F4-F5 mapping is enabled, the field "F4-F5 Used Channels" is displayed. If F4-F5 mapping is disabled, the field "F4-F5 Reqd Chans" is displayed.
F4-F5 mapping can not be enabled on ports which have VCCs provisioned with a VCI value of less than 33.

Automatic Routing Management to PNNI Migration
With Release 9.3.30, you use the cnfport command to provision a BXM port to support the XPVC segment that links the Automatic Routing Management BPX's BXM to the adjacent PNNI MGX's AXSM in the hybrid AR-PNNI network.
EUNI/ENNI Port Types
Release 9.3.30 introduces two new BXM port types: Enhanced UNI (EUNI) and Enhanced NNI (ENNI). With EUNI/ENNI ports types, all new XPVC connections added to the port are programmed as "non-segment". Non-segment connections to NOT terminate OAM segment loopback cells. This allows the OAM cells to start from an edge of the AR-PNNI network and traverse through multiple XPVC segments for end-to-end connection testing. Note that in the AR-PNNI hybrid network, UNI/NNI connections continue to be programmed as segment. Segment connections terminate OAM segment loopback cells.
The EUNI/ENNI port type configuration is required on each junction of the AR-PNNI, or AR-PNNI-AR, network and on both sides of each XPVC segment. Both the AR BXM and the PNNI AXSM port must be either EUNI or ENNI.
The cnfport command allows EUNI/ENNI port type configuration only when the XLMI protocol is enabled on the BXM port. EUNI/ENNI port types are only allowed on BXM ports with no existing connections. If the port has existing connections, cnfport blocks selection of the EUNI/ENNI port type.
The cnfport command only supports the following port type configuration combinations:
•UNI to EUNI
•NNI to ENNI
If the port type is UNI (the default port type) and the required port type is ENNI, you must first configure the port as NNI, then as ENNI. The CLI prompt specifies the combinations allowed.
The VPI range and default for the EUNI port type is the same as for the UNI port type (0-255). The VPI range and default for the ENNI port type is the same as for the NNI port type (0-4095). VSI partition and virtual ports are not supported on EUNI/ENNI port types.
XLMI Protocol and LMI Neighbor Discovery
Release 9.3.30 introduces a new BXM protocol: Extended LMI (XLMI). The XLMI protocol supports LMI Neighbor Discovery and XPVC status update in the hybrid AR-PNNI network. XLMI is only supported over an AR-PNNI link, and it only runs on the BXM interface card.
The XLMI protocol cannot be enabled if there are existing connections on the BXM port. To enable the XLMI protocol, select the "XL" value for the Protocol parameter. When the XLMI protocol is enabled, cnfport sets the default values for the following parameters:
•Protocol by Card: Y. The XLMI protocol cannot run on the BCC controller card.
•Control VC: VPI = 3/VCI = 31. This configuration is required for XLMI.
•LMI Polling Enabled: N. (Although the default is N, set this parameter to Y for the LMI Neighbor Discovery feature)
•T393 Status Enquiry Timer: 10 seconds
•T394 Update Status Timer: 10 seconds
•T396 Polling Timer: 10 seconds
•N394 Max Status Enquiry Retry: 5 seconds
•N395 Max Update Status Retry: 5 seconds
The XLMI protocol cannot be enabled or disabled if there are existing connections on the port. On ports with no connections, a warning is displayed when XLMI is disabled, and you are asked to confirm the action. If the disable is confirmed, the neighbor AXSM's information, if any, is deleted from the port and the CWM is notified.
To enable the LMI Neighbor Discovery feature, set LMI Polling to "Y" and the Advertise Interface Information parameter to "Y." When LMI Neighbor Discovery is enabled, the BXM in the Automatic Routing Management network and the AXSM in the PNNI network exchange topology information. This information includes IP address and Interface Name. The BXM reports the AXSM's neighbor information to the BCC, and the BCC reports it to the CWM.
Use parameter option 56 from the cnfnodeparm SuperUser command to configure the Management IP address to be sent to the AXSM as part of the neighbor information exchange with the AXSM. You can configure the BPX to send either the LAN IP address or Network IP address. Enter 0 for LAN IP address, or 1 for Network IP address. The default is the network IP address.
When the Advertise Interface Information is set to "N," the BXM does not send topology information to the AXSM. However, the setting of this parameter does not affect the neighbor's information. If the neighbor's information is available, the BPX reports it to the CWM. When an LMI session is downed, the BXM resets the neighbor's information to default values. The neighbor's IP address is set to NULL and the Interface Name is set to NULL string.
With Release 9.3.30, the cnfport command performs feature mismatch verification when BXM cards are replaced. If the replacement card does not support the LMI Neighbor Discovery feature, mismatch is declared under the following conditions.
1. For stand-alone BXM card replacement, mismatch is declared if the original BXM card supports LMI Neighbor Discovery and at least one port is configured for LMI Neighbor Discovery.
2. For card replacement in a Y-redundant BXM pair, mismatch is declared if the original card pair supports LMI Neighbor Discovery and at least one port is configured for LMI Neighbor Discovery.
ILMI Neighbor Discovery
The ILMI Neighbor Discovery feature is supported on ports (not virtual ports) on both the UXM and BXM cards. This feature enables a network management system, such as Cisco WAN Manager or CiscoWorks 2000, to discover other attached ATM devices, such as Cisco ATM routers or switches. The attached devices also must support ILMI Neighbor Discovery for this feature to work.
The ILMI Neighbor Discover feature on a BXM interface with virtual ports is supported on the BPX but not yet supported on CWM.
When the Advertise Interface Information parameter is enabled on a port, the BPX or IGX and the attached ATM device exchange their management IP addresses and other interface information using the ILMI protocol. The exchanged information consists of the following:
•atmfMyIfName: physical interface name
•atmfMyIfIdentifier: Interface identifier
•atmfMyIpNmAddress: Management IP Address, either the LAN IP or network IP.
•atmfMySysIdentifier: System Identifier, a 6-byte string read from the BPX NOVRAM, or if not available, the default value is "000001"
Use parameter option 56 (BPX) or 53 (IGX) from the cnfnodeparm SuperUser command to configure the ILMI Management IP address. The Management IP address is used by the network management system (NMS) to access the BPX, IGX, or attached ATM device. Depending upon your network set up, you can configure the BPX or IGX to send either the LAN IP address or Network IP address as part of the neighbor information exchange with the attached ATM device. Enter 0 for LAN IP address, or 1 for Network IP address. The default is the network IP address for the BPX or and LAN IP address for the IGX.
While the method for configuring ILMI Neighbor Discovery is the same for the BXM and the UXM, it works a little bit differently for the URM. The URM card has two parts: an embedded router and an embedded UXM port. The router runs Cisco IOS and must have its IP address configured with the router IOS command line interface accessible via an IOS console port located on the backcard of the URM card. Configure the router protocol to ILMI. The UXM port on the URM card must be configured with the IGX command line interface. Set the protocol to ILMI and enable the Neighbor Discovery feature. With this configuration, the Management IP address of the embedded router is reported to the URM embedded UXM via ILMI.
Once the parameter is set in cnfnodeparm, enable the Neighbor Discovery feature using the Advertise Interface Information parameter from the cnfport command. Set the parameters that follow, depending upon the switch.
Options that must be set for a BXM port are shown in Table 3-32.

"Protocol run on the card" or "Protocol By Card" is prompted only when the protocol is ILMI and the card supports ILMI on the card. The "Advertise Interface Information" parameter is prompted only when "Protocol run on the card" or "Protocol By Card" is set to Yes.
The switch always processes the neighbor's management IP address and IfName.Use the dspnebdisc command to display all the neighbor's information discovered by the BPX or the IGX via the ILMI Neighbor Discovery procedure.
The cnfport command, in addition to other configuration commands, performs mismatch verification on the BXM and UXM cards. For example, the cnfport command verifies that the Y-cabled redundant cards both have LMI/ILMI configured.
Refer to "Feature Mismatching" in the BPX 8600 Series Installation and Configuration. The Feature Mismatching capability will not mismatch cards unless the actual feature has been enabled on the card. This allows for a graceful card migration from an older release.
Traffic Shaping on the UXM and URM
The UXM and URM cards support the VC traffic shaping feature. VC traffic shaping shapes each connection by scheduling cells using the WFQ (Weighted Fair Queueing) technique to ensure conformance to the service provider's requirements. In general, traffic shaping provides a tight control on each connection's CDV in order to meet carrier requirements. The feature also prevents domination of bandwidth resources by any one connection.
On the UXM and URM, traffic shaping is configured on a per port basis. Once the traffic shaping parameter is turned on, all connections added afterward will have traffic shaping on. Refer to the Cisco WAN Switch Software Release 9.2 release notes for additional information on traffic shaping.
Traffic Shaping on the BXM
Traffic shaping lets you choose whether to have VC scheduling performed to your CBR, VBR, UBR, or ABRSTD with VSVD and without FCES traffic streams. You can configure the traffic shaping (which involves weighted fair queuing) option on each BXM interface. In release 9.3.05 onward, traffic shaping is enabled/disabled per QoS by using the cnfportq command.
Traffic shaping, and all traffic pertaining to the QoS for this release, is performed on a per-port basis. When a particular QoS is enabled, all traffic exiting the port is subject to the VC scheduling based on the appropriate service parameters you provision. When a particular port is configured to perform traffic shaping, all ATM cells, regardless of class of service, pass through the VC queues before leaving the card. When a traffic class is not configured for traffic shaping, its connections circumvent the VC queues and are scheduled by the Qbins.
No connections should exist on the port before changing the port traffic shaping parameter. If there are existing connections when the port traffic shaping parameter is toggled, then these connections will not be updated unless the card is reset, connections are rerouted, a switchcc occurs, or you modify the connection parameters. Also, traffic shaping is not enabled on a VSVD endpoint if an external segment has been enabled.
Redundant cards must either both support traffic shaping, or neither support traffic shaping. In the non-redundant case, traffic shaping is configurable regardless of whether the BXM card in the target slot supports traffic shaping. If the card does not support traffic shaping, then a BXM card that does support traffic shaping can be inserted later and the traffic shaping configuration will take effect. System software will not perform mismatch checking on the traffic shaping capabilities of the BXM.
The traffic shaping rate parameters are in Table 3-34. The MCR is the minimum cell rate for the connection. This is the lowest rate that the connection will be scheduled from the VC queue into the Qbin. The PCR is the peak cell rate, or the highest rate at which the connection will be scheduled from the VC queue into the Qbin.

1 Indicates that the system software issues a warning that traffic shaping is not supported on that specific BXM.
Note Traffic shaping does not generate any alarms. There is no mismatch checking for BXMs that support traffic shaping, so if you insert a BXM card with firmware that does not support it, then the traffic shaping functionality will not exist.
Note Cells can be momentarily received out of order when you reconfigure connections between traffic shaping and non-traffic shaping. This is a limitation of the hardware for which there is no workaround.
Configuring Traffic Shaping
Traffic shaping involves passing ATM traffic through the ATM interface at a VC queue, scheduled rate. With the introduction of traffic shaping, the customer will have the option to perform VC scheduling to his/her ABR, CBR, VBR, and UBR traffic streams. Traffic shaping is performed by the BXM hardware.
Traffic shaping will be performed on a per-port, per-CoS basis.
No connections should exist on the port before you change the port traffic-shaping parameter. If there are existing connections when you toggle the port traffic-shaping parameter, then these connections will not be updated unless you reset the card (by using the resetcd command), connections are rerouted, a switchcc occurs, or you modify the connection parameters. Also, it should be noted that traffic shaping is not enabled on a VSVD endpoint if external segment has been enabled.
Use cnfportq to configure traffic shaping parameters.
Firmware Functionality (BXM)
The BXM firmware supports a new CommBus parameter to enable/disable traffic shaping. When you add a connection, the BXM firmware checks its database to see if traffic shaping is enabled for the port that the connection is to be mapped to. If traffic shaping is enabled, the BXM firmware sets up the ASIC hardware to perform the weighted fair queuing. In the background, the BXM firmware runs a rate-based algorithm.
Existing functionality, such as VC queuing, is used by the traffic shaping feature.
In this release, the BXM firmware supports a new CommBus (CBUS) parameter to enable/disable traffic shaping. When a connection is added, the BXM firmware checks its database to see if traffic shaping is enabled for the port that the connection is to be mapped to. If traffic shaping is enabled for the traffic class on the port, the BXM firmware sets up the ASIC hardware to perform the weighted fair queuing. In the background, the BXM firmware runs a rate-based algorithm similar to what is done today for explicit rate stamping (ERS). The only other interface change includes an egress SCR parameter in the channel (0x52) message.
The algorithm executed by the firmware involves the BXM firmware polling the cell arrival and transmit counters of the Qbins approximately every 15 msec. During this time, the firmware determines the congestion ratio:
rc = rp * out/in
where rp is the previous value of rc, "out" is the number of cells leaving the Qbin, and "in" is the number of cells arriving into the Qbin. Note that if the ratio of out/in is less than 1, then the Qbin is experiencing congestion. The BXM firmware takes the resulting "rc" and divides this value into the sum of all of the PCRs for the Qbin and uses this result as the congestion factor to be programmed into the hardware (SABRE).
Performance of Traffic Shaping
The weighted fair queuing (WFQ) algorithm for traffic shaping runs the same algorithm as the explicit rate stamping (ERS). This processing consumes 12 percent of the bandwidth. Because the algorithm runs once (even if both ERS and WFQ are enabled), traffic shaping will not increase the worst-case demand for BXM processor time.
Errors and Alarm Handling
No alarms will be generated regarding the traffic-shaping feature. As previously mentioned, there is no mismatch checking for BXMs that do not support the feature, so if you insert a BXM with firmware that does not support the feature, then the traffic shaping functionality will not be supported on that card.
It should be noted that cells can be momentarily received out of order when connections are reconfigured between traffic shaping and non-traffic shaping. This is a limitation of the hardware for which there is no workaround.
Virtual Ports
Virtual ports ( Figure 3-20) are logical interfaces like virtual trunks, trunks, and ports. (A maximum of 31 logical entities are available on a BXM card.)
Virtual ports is an optional feature that must be configured by Cisco on the BPX.
Figure 3-20 Virtual Ports
One or more virtual ports may function on a single port connected to CPE devices, directly or through an ATM cloud. Although virtual ports, like ports, can connect directly to CPEs, they are generally used to connect indirectly.
Traffic shaping has previously been supported on ports and on connections. Virtual ports on BPX switches provide hierarchical traffic shaping, which means both virtual port traffic shaping and connection traffic shaping.
A virtual port may carry multiple PVCs or PVPs. VI traffic shaping capability is provided per virtual port. Additionally, connection traffic shaping is available on a QoS basis. While virtual port shaping is always ON, you can turn connection traffic shaping ON or OFF by using the cnfportq command.
Each virtual port supports all Automatic Routing Management (AutoRoute) traffic types that are currently supported by ports.
To set the maximum bandwidth available for use on that virtual port, use the Bandwidth parameter of the command cnfport (see Figure 3-21). This parameter is similar to the Bandwidth parameter used for ports. However, while the Bandwidth parameter is configurable on a virtual port, on a port, this parameter is not configurable; it is automatically set to the line speed.
You can configure a virtual port's bandwidth to the full port bandwidth or a subset thereof. However, the bandwidth sum of all virtual ports on a port cannot exceed the port's total bandwidth.
Figure 3-21 Port Bandwidth
Requirements
Virtual ports are available on the BXM card for the BPX. This feature is included in BPX Switch Software 9.3.10. and is independent of firmware. Virtual ports are not supported on ASI card connections.
On the BPX, this feature requires:
•BCC 3-64 or BCC 4-128 controller card
•BXM card
Depending on the interface type, UNI or NNI, the maximum number of PVPs will be 255 or 4095 respectively. The maximum number of VCIs is 65535.
Port Bandwidth and Line Speed
Figure 3-22 shows the types of bandwidth that make up the port's total bandwidth as configured by cnfport.
Figure 3-22 Port Bandwidth and Line Speed
Total Port Bandwidth
The total port bandwidth is the bandwidth of the port. It is configured by the cnfport command. Its units are cells per second. If there are multiple ports on a line (physical interface), then the sum of the "Total Port Bandwidths" on that line is limited to be less than or equal to the line speed.
For BXM T3 lines the line speed is based on the framing, PLCP or HEC, and can be reconfigured using the cnfln command.
Automatic Routing Management Bandwidth
The Automatic Routing Management Bandwidth is the bandwidth that can be used by Automatic Routing Management connections. It is user configured via the cnfrsrc command. Its units are cells per second. It can never be larger than the total port bandwidth.
VSI Bandwidth
The VSI bandwidth is the bandwidth that is currently used by the VSI partitions. It is a calculated value based on the VSI min-BW and max-BW values. Its units are in cells per second. It is "configurable by the user" when the min-BW and max-BW values are modified via the cnfrsrc command. When being configured, the min-BW and max- BW parameters cannot be set so that they would consume more than Total Port Bandwidth-Automatic Routing Management Bandwidth.
Unused Bandwidth
The unused bandwidth is whatever is left over. This occurs if some of the non-Automatic Routing Management bandwidth is unused by VSI.
Limitations
The BXM card has 31 Virtual Interfaces (VIs). These VIs can be used for Virtual Ports, Virtual Trunks, Physical Ports or Physical Trunks.
•The maximum number of interfaces (Virtual/Physical Port/Trunk) per BXM is equal to the maximum number of VIs. Therefore, a maximum of 31 (BXM) Virtual Ports are supported per card. The maximum number of Virtual Ports is 31 (BXM), but the number of available Virtual Ports can be lower based on the number of other interface types in use.
•A maximum of 254 ports (physical or virtual), are supported on the BPX node with the BCC 4-128 controller. A maximum of 144 Virtual Ports will be supported on a BPX node running the BCC 3-64 controller. Virtual Ports are not supported on controllers lower than BCC 3-64 (BPX). The maximum Virtual Ports available will be reduced by the number of Physical Ports on the system.
•Some port parameters are physical, and therefore when they are changed on one Virtual Port, they will change the same parameter on all other Virtual Ports that reside on the same Physical Port. Others apply only to the Virtual Port. A description of all the parameters is listed in Table 2-65.
•The total number of connection channels per card is shared by all interfaces on the card. The number of channels used by all the interfaces on a card cannot exceed the total number of channels on the card. The number of channels on a given interface is further limited by the port group to which it belongs.
•The number of port groups limits the number of channels that may be used on an interface. For example, consider an 8-port BXM card with two port groups and a total of n channels. Each port group may access a pool of n/2 channels. Each port may only access the channels in its port group, so each interface is limited to a maximum of n/2 channels.
•The total bandwidth per Physical Port is shared by all the Virtual Ports on that Physical Port. The bandwidth sum of all the Virtual Ports on the Physical Port cannot exceed the bandwidth of the Physical Port.
•Queue depth per port is shared by all the logical (Physical/Virtual Port/Trunk) interfaces on the card. The queues are dynamic, which allows oversubscription of the available queue space. The sum of all the configured queue depths may be larger than the available queue space on the card.
a. T1 (UXM card only) 3,622 cells/second
b. T3 (PLCP mode) (BXM) 96,000 cells/second
c. T3 (HEC/Direct mapping mode) (BXM) 104,000 cells/second
d. E3 (BXM) 80,000 cells/second
e. OC3 (BXM) 353,208 cells/second
f. OC12 (BXM) 1,412,830 cells/second
•Virtual Port traffic shaping is always ON, connection shaping is configurable per QoS.
cnfportq (configure port queue parameters)
Configures queue parameters for a port on an ASI or BXM card on the BPX, or a UXM card on the IGX. Pressing the Return key keeps the current value for the parameter.
You can use cnfportq to configure Qbin values separately for rt-VBR and nrt-VBR connection types on ports. (To configure the Qbin values for rt-VBR and nrt-VBR classes of service on trunks, use cnftrkparm.) The rt-VBR and nrt-VBR connections use different queues on a port: these are the rt-VBR and nrt-VBR queues, respectively.
For information on configuring trunk queues used by rt-VBR and nrt-VBR connections, see the cnftrkparm command.
The VBR class of service type can be either rt-VBR or nrt-VBR, depending on the way the corresponding port (service) queues (both ingress and egress) are configured. For the nrt-VBR class of service type in this release, the corresponding service queues are large enough to provide efficient bandwidth sharing with other non-real-time service types. The service queues for both rt-VBR and nrt-VBR service types can be configured on a node-by-node basis.
In Release 9.3.0, you can enable connection shaping for BXM queues. (See Hierarchical. Traffic Shaping on the BXM Card.)

cnfportstats (configure port statistics collection)
Configures parameters for statistics collection on ports. The primary purpose of this command is debugging. Table 3-35 lists the configurable statistics for a Frame Relay port. For port statistics in general, refer to the actual cnfportstats screens on a node. Not all statistic types are applied to all ports.
Qbin statistics are Cells Served, Cells Discarded, and Cells Received.
Here is a summary of all Qbin statistics collected by the BPX and IGX:
•UXM and BXM Qbins 1-9 on Automatic Routing Management trunks.
•BXM Qbins 0-3, 9 on Automatic Routing Management ports.
•UXM Qbins 2,3, 7-9 on Automatic Routing Management ports.
•UXM and BXM Qbins 10-15 on VSI ports and trunks.
All other Qbins are unused, and the switch does not provide statistics for them. Starting in switch software release 9.3.10, the switch provides the collection of Qbin Cells Discarded statistics via SNMP for the above mentioned Qbins.

cnfpref (configured preferred route for connections)
Specifies the preferred route for a connection or range of connections. Enter cnfpref only at a node that is an end point of the connection. This command applies only to connections that exist within a domain. Do not attempt to execute cnfpref on connections that exist between domains.
The preferred route for a connection is used when possible. If the preferred route is different from the existing route, the connection automatically moves to the preferred route whenever network conditions allow (for example, when trunks are out of alarm and sufficient bandwidth exists).

cnfprt (configure printing functions)
Configures the printing function. To obtain local or remote printing at a node, a printer must connect to the AUX PORT. Also, the configuration must include the correct baud rate and printer type for the port. Use the cnfterm and cnftermfunc commands to do this.
The cnfprt and cnftermfunc commands interact. If the auxiliary port on the node is configured for either an External Device Window or the Network Management Log, a "local" printing configuration automatically changes to "no printing." Printing is not possible because the auxiliary port is being used for another purpose.
Establishing a virtual terminal connection with a node does not affect the printing location established for the node that initiates the virtual terminal connection. For example, if node alpha is configured so that all alpha information goes to a printer at node beta and if alpha establishes a virtual terminal connection with node gamma, the results of print commands entered on the alpha keyboard still print at beta. Furthermore, this occurs regardless of the printing location configured for node gamma.

cnfpwd (configure password)
Changes the password associated with a User ID. To change a password, you must log into the node with the User ID whose password you want to change. Passwords are case-sensitive.
In a structured network, each domain requires you to have a password. In each domain, your password and associated privilege level can be the same as or different from those in the other domains. For each domain, you can change the password at any node within the domain, including a junction node.

cnfqbin (configure Qbin)
Configure the Qbin (class of service buffers) on a selected UXM or BXM port, physical trunk, or virtual trunk. The cnfqbin command prompts you whether "template" should be used for Qbin parameters.
As an option, you can accept the default values from the interface service class template. For example, you can type in Yes when prompted whether the interface service class template (SCT) should be used, and the command will use the Qbin values from the Qbin templates. You will not be allowed to enter values for any Qbin parameter in this case. If you do not choose the template option, you can enter desired values.
When a VSI interface is activated, the default template (MPLS1) is assigned to an interface. The corresponding Qbin template is copied into the card Qbin data structure for that interface. When you want to change this, by giving new values using the cnfQbin command, the Qbin is now user configured as opposed to template configured. This information is displayed on the dspQbin screen. It indicates whether the values in the Qbin are from the template assigned to the interface OR the values have been changed to user-defined values.
There are 16 Qbins (numbered 0 through 15) per interface. Only Qbins 10-15 are used by VSI and they are the only VSI Qbins you can configure.
To fine tune traffic delay, use the cnfqbin command to adjust the thresholds for the traffic arriving in the VSI Qbins for a given interface.
If you use the cnfqbin command to set an existing Qbin to disabled, the egress of the connection traffic to the network is disabled. Re-enable the Qbin to restore the egress traffic.
Note Cell delay variation (CDV) is based on the Qbin depths and the transmission speed of the virtual switch interface. The default Qbin depths are specified in the service class templates (SCTs). You can configure the Qbin depths by using the cnfqbin command.
Cell tolerance delay (CTD), which is the fixed delay, is based on a fixed value, and is not configurable.Syntax

cnfrobparm (configure robust alarms parameters)
Sets parameters associated with the Robust Alarms feature. Robust Alarms is a protocol for node-to-Network Management System (NMS) communications. When a node has statistics or alarm information for the NMS, it requires a confirmation from the NMS that the database has been updated.
In Release 9.2 and higher, there are robust alarms for certain alarm conditions that appear in the maintenance log or in the node user interface but are not also reported as SNMP traps to the customer NMS. (Such traps are generated by the Cisco WAN Manager RTM proxy upon receiving Robust Alarms from a switch.) Robust Alarm messages are generated by the following alarm conditions:
•Power supply, temperature, fan, and DC voltage level alarms
•Connection AIS alarm
•Bus failure
•External clock source failure
•Multiple invalid login attempts on a user port
•Excessive CPU and memory usage on switch processor card
The BPX and the IGX generate power supply, temperature, and fan alarms.

cnfrrcpu (configure CPU-based reroute throttling level parameters)
When the CPU utilization exceeds the defined threshold, routing is suspended. Throttling thresholds can be independently set for master, via, and slave routing. In addition, a hysteresis mechanism is provided to prevent excessing oscillation, using the parameter <resume_diff>).
Note Throttling is based on the CPU utilization of the TRNS task and all tasks with the same or higher priority. Hence, activity of low-priority tasks such as FAIL or SNMP will not cause routing to be throttled.

cnfrsrc (configure resource)
Use the cnfrsrc command to partition resources for:
•Automatic Routing Management PVCs
•VSI-MPLS (Multiprotocol Label Switching)
•VSI-PNNI (Private Network to Network Interface)
If you want to configure resources for a VSI-MPLS controller or PNNI SVCs, refer to the subsequent BPX- and IGX-specific command definitions.
Up to two controllers of the same type can be attached to a node and assigned the same partition to provide controller redundancy on that partition. A different set of controllers can be attached to the node and be assigned a different partition to provide controller redundancy on this second partition.
You can configure a virtual trunk to be dedicated to VSI or to Automatic Routing Management. You cannot configure a virtual trunk for both VSI and Automatic Routing Management.
This command supports physical trunks and virtual trunks. After VSI has been enabled, the virtual trunk becomes a "dedicated" VSI virtual trunk. If the trunk has already been added or if the VPI value has not been configured, switch software will prevent you from configuring the VPI value.
The switch software:
•Allows start VPI = 0 for a VSI partition on a port interface, or feeder trunk interface.
•Prevents a second VSI partition from being enabled on a port interface if the first VSI partition uses a start VPI = 0.
•In release 9.2.30 and release 9.3.0, prevents a VSI partition from being disabled on a trunk interface if a PNNI controller is attached to the trunk interface controlling partition being disabled. This restriction has been removed starting with Release 9.3.05) going forward.
Configurable Resources
You can use cnfrsrc to configure these resources:
•Template number (new field in Release 9.2)
•Maximum PVC LCNs
•Maximum PVC Bandwidth
•Configure PVC VIP ranges (Y/N)
•Start of PVC VPI range 1
•End of PVC VPI range 1
•Start of PVC VPI range 2
•End of PVC VPI range 2
•Start of PVC VPI range 3
•End of PVC VPI range 3
•Start of PVC VPI range 4
•End of PVC VPI range 4
•Configure Partition (Y/N)
•Partition ID
•Enable Partition (Enable/Disable)
•Minimum VSI LCNs
•Maximum VSI LCNs
•Start VSI VPI
•End VSI VPI - Warning message will tell you that the end VSI VPI is equal to the start VSI VPI for virtual trunks
•Minimum VSI Bandwidth
•Maximum VSI Bandwidth
The resources that you can configure are the number of connection IDs (conids) and the trunk bandwidth. You use the cnfrsrc command to configure the cell rate and number of connections on a BXM card only. (You cannot use the cnfrsrc command on the IGX.)
You configure all port and trunk attributes by using cnftrk, cnftrkparm, or cnfrsrc. When you change a physical port attribute, you are notified that all the logical (physical and virtual) trunks on the port are affected.
When using cnfrsrc to configure partition resources for Automatic Routing Management PVCs, you are prompted whether you want to configure VSI options. Enter "n" for No. You will not be prompted to enter any VSI options.
Use the cnfrsrc command to configure conids (lcns) and bandwidth. The conid capacity indicates the number of connection channels on the trunk port which are usable by the virtual trunk.
This number cannot be greater than the total number of connection channels on the card. The maximum number of channels is additionally limited by the number of VCI bits in the UNI cell header. For a virtual trunk, the number is divided by the maximum number of virtual trunks on the port to determine the default. Use the cnfsrc command to configure this value on the BPX. Table 3-38 lists the number of connection IDs for virtual trunks on various cards.

Parameters
Parameter Descriptionslot.port.vtrk
Specifies the BXM card slot and port number and virtual trunk.
Maximum PVC LCNs
The maximum number of LCNs allocated for Automatic Routing Management PVCs for this port. The range depends upon the card type; (1-11771 for the BNI T/E3 and 1-15867 for the BNI OC) 256 is the default. The default is 256 only if 256 are available. If other ports and trunks on the card have been configured to use LCNs such that there are only 100 remaining, then the default value for the newly added port would be 100. In this instance trunk upping would be blocked indicating that there are not enough LCNs to support the trunk.
For trunks, there are additional LCNs allocated for Automatic Routing Management that are not configurable.
You can use the dspcd <slot> command to display the maximum number of LCNs you can configure using the cnfrsrc command for the given port. For trunks, configurable LCNs represent the LCNs remaining after the BCC has subtracted the networking LCNs needed. A trunk has 270 networking LCNs, or channels. You can use the dspcd command to display VSI channels also.
For a port card, a larger number is shown, as compared with a trunk card. This is because a trunk uses 270 networking LCNs, as compared with a port card, which uses no networking LCNs. You can use dspcd to display VSI channels also.
Setting this field to "0" would disable Automatic Routing Management PVCs on the specified port.
Note You must specify a value greater than 0 for the Maximum PVC LCNs, Maximum PVC Bandwidth, and Maximum VSI LCNs parameters. Otherwise, you will not be able to create any Automatic Routing Management connections on a BXM card. Also, if these parameters do not have values greater than 0, you will be unable to change the connection channel amount when you configure the BXM trunk by using cnftrk.
Logical Interface (slot.port [.vtrk] for trunks and slot.port for lines).
The bandwidth is logical interface based.
Default: the line rate of this interface.
Maximum PVC Bandwidth
Specifies the maximum bandwidth of the port allocated for Automatic Routing Management use depends upon the card type; (1-11771 for the BNI T/E3 and 1-15867 for the BNI OC); 256 is the default. The default is 256 only if 256 is available. If other ports and trunks on the card have been configured to use LCNs such that there are only 100 remaining, then the default value for the newly added port would be 100. In this instance trunk upping would be blocked indicating that there are not enough LCNs to support the trunk.
You can configure the Maximum PVC Bandwidth value for ports, but not for trunks.
Note You must specify a value greater than 0 for the Maximum PVC LCNs, Maximum PVC Bandwidth, and Maximum VSI LCNs parameters. Otherwise, you will not be able to create any Automatic Routing Management PVCs on the BXM card.
Note Changing the line framing for BXM-T3 cards from PLCP to HEC no longer automatically changes the port's bandwidth to the new maximum. It merely raises the upper limit for the port's bandwidth. After changing the framing, you must use cnfport to increase the port's bandwidth, and cnfrsrc to increase the port's Automatic Routing Management bandwidth (PVC Max Bandwidth).
You can define the PVC VPI ranges for Automatic Routing Management connections by using the cnfrsrc command. However, overlapping of the PVC and VSI VPI ranges are allowed only on a physical port or feeder trunk interface. When configuring the overlapping ranges, you will receive a warning of "Warning - VPI overlaps with AR range x". The command will be stopped if you answer y and will proceed if you answers n. The cnfrsrc screen contains a warning message: Note that the "*" next to the VPI fields indicate the overlapping PVC (Automatic Routing Management and VSI VPI ranges).
Configure PVC VCI Range
You will be prompted when configuring a port or feeder trunk only. Answer Yes or No to begin configuring the PVC VPI range. Enter Y if you are migrating PVCs on this interface to PNNI SPVCs, otherwise answer N. If you enter Y, you will be prompted for the four PVC VPI ranges.
Start of PVC VPI range x
You can define 4 VPI ranges. ALl the existing PVCs have to be using a VPI in one of the defined PVC VIP ranges.
End of PVC VPI range x
Together with Start of PVC VPI range, it defines a VPI range for PVCs.
Configure Partition
Answer yes or no to begin configuring resources for the partition. To configure Automatic Routing Management PVCs, enter n for No. You will not be prompted to enter VSI options to configure VSI partition resources.
However, if you want to configure VSI options, enter y for yes, and you will be prompted to configure partition resources for VSI. (Refer to the command cnfrsrc (configure VSI resources for IGX) and cnfrsrc (configuring VSI resources for BPX) for more information on VSI-related optionsPartition ID
Specifies the ID number of the partition. In previous releases, use 1. In release 9.1, use 1 for the partition ID.
Default: 0
Range: 1 - 3Enable Partition
Answer yes or no to enable your configured partition.
Minimum VSI LCNs
The minimum number of LCNs guaranteed for this partition. Range is from 0 to card limit: 0 is the default. The VSI controller guarantees at least this many connection endpoints in the partition, provided there are sufficient free LCNs in the common pool to satisfy the request at the time the partition is added. When a new partition is added or the value is increased, it may be that existing connections have depleted the common pool so that there are not enough free LCNs to satisfy the request. The BXM gives priority to the request when LCNs are freed. The net effect is that the partition may not receive all the guaranteed LCNs (min LCNs) until other LCNs are returned to the common pool.
You can increase this value dynamically when there are enough unallocated LCNs in the port group to satisfy the increase.
You may not decrease the value dynamically. All partitions in the same port group must be deleted first and reconfigured in order to reduce this value.
To avoid this deficit condition, which could occur with maximum LCN usage by a partition or partitions, it is recommended that all partitions be configured ahead of time before adding connections. Also, it is recommended that all partitions be configured before adding a VSI controller by using the addshelf command.
Maximum VSI LCNs
The total number of LCNs the partition is allowed for setting up connections. The min LCNs is included in this calculation. If max LCNs equals min LCNs, then the max LCNs are guaranteed for this partition.
Otherwise, (max - min) LCNs are allocated from the common pool on a FIFO basis.
If the common pool is exhausted, new connection setup requests will be rejected for the partition, even though the maximum LCNs has not been reached.
You may increase this value dynamically when there are enough unallocated LCNs in the port group to satisfy the increase.
You may not decrease the value dynamically. All partitions in the same port group must be deleted first and reconfigured in order to reduce this value.
Different types of BXM cards support different maximum values. If you enter a value greater than the allowed maximum, a message is displayed with the allowable maximum value.
Note You must specify a value greater than 0 for the Maximum VSI LCNs, Maximum PVC Channels, and Maximum PVC Bandwidth parameters. Otherwise, you will not be able to add any connections on a BXM card.
Start VSI VPI
By default the LSC (for example, the 6400, 7200 or 7500 series router) will use either a starting VSI VPI of 1 or 2 for MPLS, whichever is available. If both are available, a starting VSI VPI of 1 is used. The VPI range should be 2-15 on a BPX 8620 VSI. The VSI range for MPLS on the BPX 8620 is configured as a VSI partition, usually VSI partition number 1. VSI VPI 1 is reserved for Automatic Routing Management PVCs. (This restriction applies only to trunks, not to ports. For a port, you can use any VPI value.) For a port UNI, the VPI range is 1 to 255. For a port NNI, the range is 1 to 4095. For trunks that do not have Automatic Routing Management configured, the VPI ranges are the same as for ports.
The VSI partition for MPLS should start at VPI 2. If VPI 2 is not to be used, you can use the MPLS VPI interface configuration on the LSC to override the defaults.
For trunks with Automatic Routing Management configured, the range is 2 to 4095. Always set to 2 for trunks. For ports in port mode it should be set to "1". By default the LSC (for example, 6400, 7200 or 7500 series router) will use either a starting VSI VPI of 1 or 2 for label switching, whichever is available. Default: 1
End VSI VPI
Two VPIs are sufficient, although it may be advisable to reserve a larger range of VPIs for later expansion, for example, VPIs 2-15.
Range: <Start VSI VPI > value to 4095.
Minimum VSI Bandwidth
The minimum port bandwidth that can be used by this partition in cells per second.
Range: 0 to <Maximum Line Rate>.
For example, the OC-3 line rate is 352207.
Default: 0Maximum VSI Bandwidth
The maximum port bandwidth that can be used by this partition. This value is used for VSI Qbin bandwidth scaling.
Range: 0 to <Maximum Line Rate>.
For example, the OC-3 line rate is 352207.
Default: 0

Increasing the Number of VSI LCNs Guaranteed for a VSI Partition
You can increase the number of LCNs guaranteed for a given VSI partition by increasing the Minimum VSI LCNs of the desired partition.
If the new number does not cause the total VSI LCNs to be increased (that is, if your want to increase the minimum VSI LCNs at the expense of the common pool), the request will be denied if there isn't enough free VSI LCNs in the common pool. The UXM card cannot find enough free VSI LCNs to give to the specified partition. More AR LCNs must be made available to VSI for the request to succeed. The cnfrsrc will display a message: Resource not available, maximum available LCN(s) is 50. 100 more LCN needed. This indicates the number of AR LCNs that should be made available to the VSI.
cnfrsrc 12.1 256 20000 y 1 e 900 1500 300 400 4000 6000
Decreasing the VSI LCNs
You can decrease the VSI LCN range in order to make more LCNs available to AR:
•If the formula result used to compute the number of VSI LCNs, was obtained by using the Minimum VSI LCNs, then you can decrease the VSI LCN range by decreasing the Minimum VSI LCNs of any VSI partition.
•If the formula result was obtained by using the Maximum VSI LCNs, then you can decrease the VSI LCN range by decreasing the Maximum VSI LCNs of the VSI partition whose max was used to get the result of the formula.
In some cases, decreasing the VSI LCN range will fail because there are not enough free VSI LCNs to give to AR. The cnfrsrc command will display a failure message giving the number of VSI channels that can be made available to AR (There are only 100 free VSI channels). You can then re-execute the cnfrsrc requesting a smaller number of VSI LCNs to be given to AR.
If you must give more VSI LCNs to AR than what is currently free, go to the VSI master and delete or re-route the necessary number of VSI connections to free up the required VSI LCNs by executing the proper commands on the VSI master. You can then reattempt the cnfrsrc command.
Sometimes the LCNs that were freed by the VSI master are reused prior to reexecuting the cnfrsrc command. You can delete more connections on the VSI master than what is required. Or you can freeze the VSI master so that it does not add any new VSI connections until the cnfrsrc command is reexecuted.
cnfrsrc 12.1 256 20000 y 1 e 900 1500 300 400 4000 6000
Expanding the VSI VPI Range
You can expand the VSI VPI range by changing the parameters Start VSI VPI and End VSI VPI. The command cnfrsrc checks whether the new VPI range overlaps with:
•AR connections; or
•a VPI is used by VSI controllers; or
•a VPI used by another partition.
Shrinking the VSI VPI Range
You can shrink the VSI VPI range by increasing the parameter Start VSI VPI and/or by decreasing the the parameter End VSI VPI. This works only if no VSI connections use the old VPI range. For example, if there is a VSI connection and VPI 10; and if the current VSI VPI range is [5,11], then the VSI VPI range cannot be shrunk to [5,9].
Increasing VSI Bandwidth
You can increase the bandwidth of VSI by increasing the Minimum VSI Bandwidth and/or Maximum VSI Bandwidth of the appropriate VSI partition. Increasing the bandwidth of VSI may cause AR connections on a trunk to be re-routed in order to free the necessary bandwidth for VSI. You will see a warning (Warning - increasing Max VSI Bandwidth will reroute all conns on this trunk). The command will proceed only if you choose to proceed.

Decreasing VSI Bandwidth
You can decrease VSI bandwidth of VSI by reducing the values of Minimum VSI Bandwidth and/or Maximum VSI Bandwidth. This works only if the VSI connections are not using the existing bandwidth.

cnfrsrc (configuring VSI resources for BPX)
Configures resources on ports, physical trunks and virtual trunks. You can partition resources for Automatic Routing Management PVCs, VSI-MPLS (Multiprotocol Label Switching), including VC Merge, or PNNI.
This command supports both physical trunks and virtual trunks. After VSI has been enabled, the virtual trunk becomes a "dedicated" VSI virtual trunk.
The switch software will prevent you from configuring VSI:
•If the virtual trunk has already been added; or
•If the VPI value has not been configured
You can configure a virtual trunk to be dedicated to VSI or to Automatic Routing Management. You cannot configure a virtual trunk for both VSI and Automatic Routing Management.
The switch software prevents a VSI partition from being disabled on a trunk interface if a PNNI controller is attached to the trunk interface controlling partition being disabled.
It is possible to have PVCs terminating on the Label Switch Controller itself. This example reserves approximately 10 Mbps (26000 cells per sec) for PVCs, and allows up to 256 PVCs on the switch port connected to the LSC.

Feature Mismatching to Verify VSI Support
The cnfrsrc and addshelf commands, in addition to other configuration commands, perform mismatch verification on the BXM (and UXM) cards. For example, the cnfrsrc and addshelf commands verify whether the cards both have VSI 2.0 support configured.
The Feature Mismatching capability does not check mismatched cards unless the actual feature has been enabled on the card. This allows for a graceful card migration from an older release.
Resource Partitioning
The VSIs must partition the resources between competing controllers: Automatic Routing Management, MPLS, and PNNI, for example. Different types of controllers can share a node's resources. For example, Automatic Routing Management, and MPLS, or Automatic Routing Management and PNNI (SVCs), but not PNNI and MPLS, can share resources.
Up to three partitions are supported and any three may be of a single type. The user interface will block the activation of partitions with ID higher than 1 if the card does not support multiple partitions.
The resources that you need to configure for a partition are shown in Table 3-39 for a partition designated ifci, which stands for interface controller 1, in this example.
The three parameters that must be distributed are:
•number of logical connections (LCNs)
•bandwidth (BW)
•virtual path identifiers (VPI)

On each interface (port or trunk) on the BXM cards used for PNNI/MPLS controllers, two sets of resources must be divided up between traditional PVC connections and switching connections. The traditional PVC connections are configured directly on the BPX platform, and switching connections are set up by the controllers using the VSI. These resources are partitioned on each interface:
• Bandwidth
• Logical Connections
•VPI
As with all ATM switches, the BPX switch supports up to a specified number of connections. On the BPX switch, the number of connections supported depends on the number of port/trunk cards installed. On each interface, space for connections is divided up between traditional BPX switch permanent virtual circuit (PVC) connections, Label Switching VCs (LVCs), and PNNI Switching VCs (SVC).
Soft and Dynamic Partitioning
Release 9.3.10 introduces Soft Partitioning and Dynamic Partitioning in order to support the smooth introduction of another VSI controller into a BPX network already configured with an existing VSI controller, easier tuning of switch resources, and the migration of Automatic Routing Management to PNNI.
Soft Partitioning provides resource guarantees for LCNs and bandwidth per partition and a pool of resources available to all partitions in addition to the guaranteed resources. Dynamic Partitioning provides the ability to rather easily increase the allocation of a resource to a partition.
You define and manage the number of LCNs assigned to a given VSI partition by modifying the "Minimum VSI LCNs" and "Maximum VSI LCNs" fields of the cnfrsrc CLI command.
To give more LCNs from Automatic Routing Management to VSI, change the Min LCNs or Max LCNs to cause BPX software to produce a bigger number. To increase the LCNs reserved to a VSI partition, increase the "Minimum VSI LCNs" or "Maximum VSI LCNs" fields of the appropriate VSI partition. The VSI LCN boundary is moved into Automatic Routing Management if there are enough free Automatic Routing Management LCNs to fulfill the request.
If there are not enough free LCNs in the Automatic Routing Management (AR) space, the cnfrsrc command does not fulfill a request to increase the VSI LCN space. In such a case, the cnfrsrc command displays a failure message showing the number of currently free AR LCNs. You can reissue the cnfrsrc command specifying a smaller increase to the VSI partition. If that is not acceptable, you must first delete and reroute the necessary number of AR connections. Then you can attempt cnfrsrc again.
Moving the VSI LCN boundary into the Automatic Routing Management space might step over LCNs that are currently allocated. BPX software reprogram the necessary channels so that new channels out of the lower AR LCN space are picked instead. Before starting the process of reprogramming the necessary number of AR connections, the cnfrsrc command displays a warning message and waits for your permission to proceed. The warning message shows the number of Automatic Routing Management (AR) connections that will be re-programmed. After reprogramming the necessary channels the LCN boundary is moved into the Automatic Routing Management space.
Note You can migrate Automatic Routing Management (AutoRoute) connections only if the VPI range of the recipient VSI partition is adjacent to Automatic Routing Management. To migrate Automatic Routing Management connections to a non-adjacent VSI partition requires different VPIs within the recipient VPI boundary.
Information about this feature also can be found in the BPX Installation and Configuration Manual, Release 9.3.10, Configuring BXM Virtual Switch Interface.
VSI Partitioning
VSI partitioning requires the following commands and procedures:
Defining the PVC VPI Range
You can define the PVC VPI ranges by filling the VSI fields described in the previous section. In the following sample system response of the cnfrsrc command, note that the * next to the VPI fields denote that the PVC and VSI VPI space overlap. You are prompted if the overlapping VSI partition is an MPLS partition. If it is, then the command will be abort because overlapping VPI ranges between Automatic Routing Management and MPLS is not supported.
Configuring the PVC VPI ranges requires the BXM card to have VSI level 3 support. An error message is displayed if you want to configured the PVC VPI ranges but the VSI level on the card is lower than 3.
Increasing the VSI LCN Range
You can increase the number of LCNs reserved for VSI by increasing the Minimum VSI LCNs and/or Maximum VSI LCNs of the appropriate VSI partition. Increasing the VSI LCN space may cause a number of AR connections to be reprogrammed. You will see a warning: "Channel conflict, max LCN w/o reprog = 5. LCN(s) to reprogram = 20." The command will proceed only if you so choose.
Increasing the Number of LCNs Guaranteed for a VSI Partition
You can increase the number of LCNs guaranteed for a given VSI partition by increasing the Minimum VSI LCNs of the desired partition. If the new number does not cause the total VSI LCNs to be increased (that is, if you want to increase the Minimum VSI LCNs at the expense of the common pool), the request will be denied if there isn't enough free VSI LCNs in the common pool. The BXM card cannot find enough free VSI LCNs to give to the specified partition. More AR LCNs must be made available to VSI for the request to succeed. The cnfrsrc will display a message: "Resource not available, maximum available LCN(s) is 50. 100 more LCN needed." This indicates the number of AR LCNs that should be made available to the VSI.
Increasing VSI Bandwidth
You can increase the bandwidth of VSI by increasing the Minimum VSI Bandwidth or Maximum VSI Bandwidth of the appropriate VSI partition.
Note Increasing VSI bandwidth may trigger a rerouting of all connections on that trunk.
Disabling Connection Admission Control (CAC) on a Port
To oversubscribe the AR bandwidth on a given port, make sure that the CAC feature is disabled on the port. Use the cnfport command for this purpose; the CAC Override field should specify "Enabled".
cnfport <slot.port>[.vtrk] <options for E1 | T1 | E3 | T3 | OC-3 | OC-12 | E2 | HSSI | SR >
Oversubscribing AR Bandwidth on a Port
To oversubscribe the AR bandwidth on a given port, make sure that the CAC feature is disabled on the port. Refer to Disabling Connection Admission Control (CAC) on a Port for more details.
Use the cnfrsrc command to decrease the bandwidth allocated for AR and give it to the VSI partition that is going to receive the AR connections. The cnfrsrc command contains 4 fields that specify information about the bandwidth:
•Maximum PVC Bandwidth
Specifies the maximum bandwidth that can be used by AR.•Statistical Reserve
Applicable only to trunks. It specifies the bandwidth that should be set aside for node to node communications.•Minimum VSI Bandwidth
•Maximum VSI Bandwidth
The cnfrsrc command verifies that the sum of the Maximum PVC Bandwidth, Statistical Reserve, and the VSI bandwidth of all VSI partitions on the port does not exceed the port speed.
You can decrease the AR bandwidth by decreasing the Maximum PVC Bandwidth field. To increase the VSI bandwidth:
•If the total bandwidth allocated for VSI was obtained by adding the Minimum VSI Bandwidth of all the VSI partitions on the port, you can give more bandwidth to VSI by increasing the Minimum VSI Bandwidth of a given partition.
•If the total bandwidth allocated for VSI was obtained by using the Maximum VSI Bandwidth of a given partition, you can give more bandwidth to VSI by increasing the Maximum VSI Bandwidth field of the partition that was used to compute the VSI bandwidth.
In the example below you can see that all of the AR bandwidth on the port was given to VSI. Note the * next the Maximum PVC Bandwidth shows that the AR bandwidth is oversubscribed.

cnfrtcost (display connection loading)
Configures the cost cap for a connection when cost-based routing is configured.
A maximum allowable cost value (cost cap) is used during route determination to prevent selection of a route that exceeds an acceptable cost. For routing based on delay, the cost cap is the acceptable end-to-end delay for the connection type. This cap is configured network-wide per delay-sensitive connection type.
For routing based on trunk cost, the cost cap is the acceptable end-to-end cost. This cap is configured per connection. The default cost cap is 100, which is derived from the maximum hops per route (10) and default cost per trunk (10). The cost cap can be changed at any time. If the cost cap is decreased below the current route cost, the connection is not automatically rerouted. A manual reroute is required to route the connection to fit under the new cost cap. This gives you more control over the connection reroute outage.
Note The cnfrtcost is valid only at the node where the connection was added.
Syntax
cnfrtcost <connection> <max cost>
Parameters
Parameter Description<connection>
Indicates the connection endpoint (that is, slot.port.vpi.vci)
<max cost>

This is the dspcon response for 9.2.5.100 with the additional fields of Max Cost (40) and Route Cost (1). For a route optimized on trunk delay, the cost labels are updated to indicate delay: Max Cost becomes Max Delay and Route Cost becomes Route Delay.

cnfrtr (configure router configuration parameters)
Configures the parameters for the Universal Router Module (URM) embedded IOS-based router on a specified router slot. Configurable router parameters include the IOS configuration file source and the router serial port function. The cnfrtr command can be invoked on a logically active or standby slot. For additional information on the URM and a complete listing of the CLI commands that support the embedded IOS-based router, see the "Universal Router Module" section on page 2-23.
Upon start-up, reset or restart, the embedded router must load an IOS configuration file. Use the cnfrtr command to specify the source, or location, of the IOS configuration file that the router is to use. Starting with Release 9.3.30, there are three IOS configuration file sources. These sources are:
•The NPM BRAM, which stores a default blank, or basic, IOS configuration file. This is the default IOS configuration file source.
•The embedded router NOVRAM, which stores the router's running IOS configuration file.
•The URM Admin flash, which stores an IOS configuration file that is downloaded from a TFTP server. This file location is supported only with the Release 9.3.30 or higher.
By default, the URM is configured to load the basic IOS configuration file from the NPM. The NPM BRAM can be configured as the IOS configuration file source for the embedded router when the URM is installed or replaced.
With Release 9.3.20, the initial configuration on the router must be done manually using the IOS CLI. With the Release 9.3.30 Remote Router Configuration feature, however, the URM Admin flash can store an IOS configuration file that is downloaded from a TFTP server. This downloaded file can be used to start up the router with an initial configuration, eliminating the need for console access to the embedded router. See the "URM Remote Router Configuration Feature" section for additional information.
During normal operations, the running IOS configuration file is stored in the embedded router NOVRAM. The running IOS configuration file is required for the router to resume normal operation in the event of a card reset or restart. The router NOVRAM can be configured as the IOS configuration file source for the embedded router during normal operations.

URM Remote Router Configuration Feature
Starting with Release 9.3.30, the URM supports the Remote Router Configuration feature. This feature allows you to start up or restart the URM embedded IOS router with an IOS configuration file that is downloaded from a TFTP server. The process of passing the IOS configuration file to the URM embedded router is similar to the process of downloading firmware images to cards. The steps in the transfer process, and the IGX CLI commands utilized, are summarized below.
•Clear the NPM RAM buffer of firmware images, save/restore configuration files, and any previous IOS configuration files. Use the dspcnf command to display the configuration save/restore status of the network nodes and identify nodes reserved for firmware images or IOS configuration files. Use the getfwrev <cardtype>0.0 to clear firmware images. Use the savecnf clear command to clear save/restore configuration files. Use the clrrtrcnf command to clear IOS configuration files.
•Create a directory and the IOS configuration file on the TFTP server from which the file is to be transferred. Use the cnfrtrcnfmastip command to specify the IP address of the authorized TFTP server.
•Send a TFTP Start file (through TFTP put) to the IGX node to initiate transfer of the IOS configuration file to the NPM RAM buffer. The interface for transferring the IOS configuration file is the same interface used to transfer firmware images. Use the dsprtrcnfdnld command to monitor the progress of the file transfer.
•Copy (or burn) the IOS configuration file from the NPM RAM buffer to the URM Admin flash. Use the burnrtrcnf command to copy the configuration file. Use the dsprtrcnfdnld command to monitor the progress of the copy activity.
•Use the cnfrtr command to configure the URM Admin flash as the source of the IOS configuration file stored in the URM Admin flash. With this configuration, the router uses the configuration file stored in the URM Admin flash at start up and upon reset or restart.
The interface for transferring the IOS configuration file is the same as the interface for transferring firmware images by TFTP. A Start file is sent to the node through TFTP put. The Start file contains the information to start the IOS configuration file download. Upon receipt of the Start file, the IGX node drives the process of transferring the IOS configuration file from the TFTP server to the NPM RAM buffer. The RAM buffer used is the same buffer used to store firmware images and node configuration save/restore files.
The name of the TFTP Start file for the IOS configuration file is always dnld.rtr. The Start file format is described below.
TFTP_REQUEST
•IP: <IP_address>. Specifies the IP address of the TFTP server storing the IOS configuration file.
•Path Name: <pathname>. Specifies the path name to the IOS configuration file stored on the TFTP server.
•File Name: <filename>. Specifies the name of the IOS configuration file stored on the TFTP server.
cnfrtrcnfmastip (configure router configuration download initiator TFTP server IP)
Configures the IP address of the authorized TFTP client which could initiate the TFTP start file transfer. This command ensures that only an authorized client initiates the transfer of the IOS configuration file.
The cnfrtrcnfmastip command supports the URM Remote Router Configuration feature introduced in Release 9.3.30. This feature allows you to start up or restart the URM embedded IOS router with an IOS configuration file that is downloaded from a TFTP server. For additional information on the URM and Remote Router Configuration feature see the cnfrtr command description.

cnfsysparm (configure system parameters)
Configures various system (or network) parameters. Network-wide parameters are configurable only when all nodes in the network are reachable. The parameters you specify with this command apply throughout the network regardless from which node you execute the command. Take special note of the consequences of how you resolve conflicting values when networks are joined.
You can select each parameter by its index number. The "System Parameters" subsection describes each parameter by index number. The "Parameter Values" table lists the defaults and ranges for each parameter.
Warning Using cnfsysparm requires caution because network rerouting or loss of data may result from changes in system parameters. If necessary, consult with the TAC before you use cnfsysparm.
Syntax
cnfsysparm <index> <value>
Parameters
System Parameters
The configurable system parameters are listed by index number:
1: Maximum Time-Stamped Packet Age is the maximum age a time-stamped packet can have before the switch discards it. If networks are joined and the Maximum Time-Stamped Packet Age in the networks differ from each other, the lower value becomes the maximum.
2: Fail Connections On Communication Break determines whether connections are conditioned if the node at the other end of the connection becomes unreachable. If networks with different settings are joined, the resolution is to enable this parameter for the new network.
3-7: Maximum Network Delay for various types of compressed voice and high-speed data connections using LDM/HDM on an IGX node. When the total queueing delay on a route exceeds this value, connection traffic cannot use the route. The units of measure are milliseconds. When networks with different values are joined, the lower value becomes the Maximum Network Delay.
8-12: Maximum Network Delay for compressed voice and high-speed data connections. When the total queueing delay on a route exceeds the specified number of milliseconds, a connection traffic cannot use the route. When networks with different values are joined, the higher value becomes the Maximum Network Delay. Applicable cards are the UVM, CDP, or CVM.
In Release 9.1, when cost-based routing is configured, the delay cost cap is the maximum allowable end-to-end delay for the connection type. Use parameters 3 through 12 to configure this delay network-wide for all delay-sensitive connections.
•13: Enable Discard Eligibility (DE) bit for Frame Relay connections. Frames received with DE set have been sent on connections where the PIR has been exceeded and are eligible to be discarded. Enabling DE automatically enables CLP. CLP is disabled when Discard Eligibility is turned off except on the bursty data B queue when ForeSight is enabled.
•14: Use Frame Relay Standard Parameters Bc and Be allows you to substitute the Frame Relay Forum standard Bc for VC Q depth and Be for PIR when you configure Frame Relay ports and connections. (The affected commands are cnfport, addcon for Frame Relay, and cnfcon.) Screen displays for Frame Relay ports and connections reflect the choice for this parameter. Note that if you change this parameter, a network-wide reset to the default values takes place for all Frame Relay classes, and the terminal displays a warning that the reset occurred.
•Obsolete: 15-20: Maximum Local Delay for Interdomain UVM, CDP, or CVM to UVM, CDP, or CVM connections is similar to parameters 8-12 described above. These parameters specify the maximum delay at the local domain in a structured network. These delays can be set only on a domain-by-domain basis (not end-to-end).
•21: FastPAD Jitter Buffer Size is the size of the buffer for neutralizing jitter in connections that terminate on a FastPAD. The units of measurement are milliseconds.
•22: Number of Consecutive Invalid Login Attempts to Cause Major Alarm specifies the number of failed login attempts that causes a major alarm. The default of 0 means that failed login attempts do not cause an alarm. If the threshold is set to 0, the Too Many Invalid Login Attempts service-affecting alarm is disabled and no alarm will be generated.
•23: Enable Connection Deroute Delay is an enable that causes the network to wait a period of time before rerouting connections because of an error on a trunk. With Enable Connection Deroute Delay enabled, the network does not immediately reroute connections when statistical errors are occurring or when a trunk momentarily moves into a failure state then returns to normal operation. This feature is relevant when rerouting the connections is more of a disruption than the errors caused by the intermittant trunk.
•24: Frame Relay VCs Polling Rate is the period between the start of polling cycles for both ATM and Frame Relay virtual connections. The possible values are 5, 10, and 15 seconds. As the number of connections in a network grows, greater intervals between cycles may be appropriate. The suggested intervals for the numbers of connections are:
–5 minute polling for up to 4000 connections
–10 minute polling for up to 8000 connections
–15 minute polling beyond 8000 connections.
•25: Port Polling Rate is the time between the start of polling cycles for interval statistics. The possible values are 5, 10, and 15 minutes. (To specify the particular statistics, use the statistics manager in WAN Manager.) As the number of connections in a network grows, greater intervals between cycles may be appropriate. The suggested intervals for the numbers of connections are:
–5 minutes for up to 300 connections
–10 minutes for up to 500 connections
–15 minutes for more than 500 connections.
•26: Num of Nodes doing Simultaneous TFTP Cnfg Save/Restore is the total number of nodes that can perform TFTP configuration data transfers simultaneously. The value must be the same on all nodes in the network. This parameter indicates the maximum number of simultaneous sessions. However, the actual number of simultaneous sessions can be less than this number, depending on the node numbering configuration in the network. When networks with different values of this parameter are joined, the resolution is to take the lower number. Range is 1 to 15 nodes. Default value is four nodes.

cnfterm (configure terminal port)
Configures data transmission parameters for the control and auxiliary ports. The IGX and BPX nodes support two EIA/TIA-232 serial ports on the upper bus expansion card. The top port is called the Control Terminal port. The lower port is called the Auxiliary Port (AUX).
Parameters can vary with the equipment connected to the port. The control port may connect to a control terminal, a direct-dial modem, or an external EIA/TIA-232 device. The auxiliary port may connect to either a printer or an external EIA/TIA-232 device. After you have set the data transmission parameters for a port, use the SuperUser command cnftermfunc to specify the equipment attached to the port. The configuration parameters must match the equipment physically attached to the port.

The Control Terminal port can connect to a control terminal, Cisco WAN Manager, a direct dial-in modem, or any external EIA/TIA-232 device. The Aux Port can connect to a printer, an auto-dial modem to call a control center, or an external EIA/TIA-232 device.
The interface specified for the port must match the equipment physically attached to the port. The baud rate and other data transmission parameters for the port are set with the cnfterm command. If either port is configured as an external device window, enter the window command to begin a session with the external device.
If the auxiliary port is configured as an auto-dial modem, designate a network ID and a phone number. Configuring the auxiliary port for an auto-dial modem enables the following to occur: When a change in alarm status happens anywhere in the network, the auto-dial modem attached to the auxiliary port dials the specified phone number. If the call goes to the TAC, the alarm is logged under the specified network ID. With this log, Cisco engineers are automatically notified of any problems that occur in the network.

Next Command:
cnftrk (configure trunk)
Configures trunk parameters. The typical procedure to add a trunk to the network includes the following steps.
1. Use uptrk to "up" or activate the trunk with a default configuration.
2. Use cnftrk to configure trunk parameters. You must execute cnftrk at both ends of a trunk.
3. Use addtrk to add the trunk to the network.
For additional information on adding and configuring trunks, see the <CellCommandItalic>Cisco BPX Series Installation and Configuration guide and the Cisco IGX 8400 Installation and Configuration guide. Also see the "Physical and Virtual Trunk Configuration" section, the "IMA-Compliant Trunk Configuration" section, and the "Subrate and Fractional Trunk Configuration" section.
In the display for cnftrk, the current value for each parameter appears on screen. At the command line prompt for each parameter, the current or default value appears in parentheses and stays the same if you press Return without entering a new value. Configurable parameters depend on the trunk type. If a displayed parameter is not available for the current trunk type, its name displays at half-intensity, and the value field contains dashes.
If you specify cnftrk in a job, prompts appear for line format and line options when you create or edit the job by using addjob or editjob, respectively.
The cnftrk command configures a logical trunk (physical or virtual), so when you change a physical parameter, all trunks on the port (both physical and virtual) are affected. For example, if you change the line framing on a virtual trunk, all virtual trunks on the port are automatically updated to have the modified line framing.
The cnftrk command supports the CBR, ABR, and VBR (rt-VBR and nrt-VBR) traffic classes on both physical and virtual trunks.
You use cnftrk to configure the Transmit Trunk Rate for all BPX cards except the BXM. For BXM cards, you must use the cnfrsrc command to configure the Transmit Trunk Rate (trunk load). For IGX cards, you configure the Transmit Trunk Rate only after a trunk has been added.
You use the cnftrk command to assign a VPI value. You cannot configure the VPI value if the virtual trunk is already configured for VSI. If the VSI feature is enabled, and you execute cnftrk to decrease the transmit rate, you must confirm whether the Qbin configuration is set up correctly by using the cnfqbin command to change the value. The reason for this is that when the transmit rate is decreased, the Qbin depth will be automatically recalculated.
Starting with Release 9.3.30, you can configure an incremental cell delay variance (CDV) on BNI, BXM, UXM, and NTM trunks. For more information about the CDV, see the description of this parameter in parameter table in this section. In addition, you can configure BXM and UXM virtual trunks to recognize receipt of end-to-end F4 OAM AIS alarms from the ATM service provider. See the "Trunk AIS OAM Recognition" section for more detail.
Also starting with Release 9.3.30, the CRC-4 Protection feature allows you to enable/disable the CRC check on multiframed UXM E1 trunks. This feature applies to all types of UXM E1 trunks except unframed E1 trunks. The two ends of the UXM E1 trunk must be configured to work together. Mismatch of CRC-4 protection configuration between the two ends of the UXM E1 trunk, will result in Out of Frame alarms on the trunk. You use the cnftrk Line CRC parameter to enable/disable the CRC check.
Table 3-41 below shows the trunk parameters that you can configure using cnftrk. You can specify all physical options on virtual trunks. If you change a physical option on a virtual trunk, the change is propagated to all virtual trunks on the trunk port.
In the table, an X indicates that the parameter is configurable. An X* in the Virtual column indicates that the parameter is a physical parameter, and changing the value for one virtual trunk on the port will automatically cause all virtual trunks on the port to be updated with the same value.

Physical and Virtual Trunk Configuration
Physical and virtual trunk configuration is similar. When you configure a port-level characteristic of a virtual trunk, all the virtual trunks on the port are modified with that characteristic. When the port characteristics of a trunk are modified, all characteristics related to that trunk port are updated.
Virtual trunks (see Table 3-43 for default statistical reserves) appear in the routing topology map as available trunks for routing. The existing physical trunk characteristics, such as bandwidth and satellite/terrestrial type, apply to virtual trunks. The routing algorithm must take into account special restrictions and conid assignments for a virtual trunk. For example, VPCs cannot be routed over a virtual trunk. Also, each virtual trunk has a configurable number of connection channels reserved from the card. The routing algorithm checks for adequate channel availability on a virtual trunk before selecting the trunk for the route.
The connection channel management scheme for the UXM and BXM cards is the same as in the previous release. The conids are selected on a per logical trunk basis. The associated LCNs are selected from a pool of LCNs for the entire card. Each virtual trunk can use the full range of acceptable conid values. The range consists of all the 16-bit values (1-65535), excluding the node numbers and blind addresses. A port uses the VPI to differentiate connections that have the same conid.
The number of channels per virtual trunk can be changed after the trunk has been added to the network. Decreasing the number of channels on an added virtual trunk causes connection reroutes where increasing the number of channels on an added virtual trunk will not cause connection reroutes.

Trunk AIS OAM Recognition
With the Release 9.3.30 AIS OAM Recognition feature, virtual trunks recognize receipt of end-to-end F4 OAM AIS alarms from the ATM service provider. Prior to Release 9.3.30,virtual trunks recognized ILMI traps/responses as a source of Virtual trunk path failure.
The AIS OAM Recognition feature is provided on BPX BXM and IGX UXM cards only. Virtual trunks in a VP-tunnelling configuration (IGX) are not supported.
The absence or presence of ILMI support from the ATM service provider does not affect the functionality of detecting F4 OAM AIS. Similarly, absence or presence of AIS indication from the ATM cloud does not affect the functionality of ILMI.
The Virtual Trunk Path Fail states have been expanded to distinguish between failures due to ILMI and AIS. The trunk states now include:
•Clear state
•Virtual Trunk Path Fail state due to ILMI trap
•Virtual Trunk Path Fail state due to AIS
•Virtual Trunk Path Fail state due to both ILMI and AIS
You use the cnftrk F4 AIS Detection parameter to enable/disable the AIS OAM Recognition feature. You use the dsptrks command to display the state of all trunks on the node.
The AIS OAM Recognition feature provides a new entry point into the Virtual Trunk Path Failure alarm. Consequently, more connection rerouting may occur. You can use the cnftrk Trunk Deroute Delay timer to avoid excessive rerouting during brief outages.
Receive and Transmit Rates on Physical Trunks
The parameters RCV Trunk Rate and Transmit Trunk Rate apply to physical ATM trunks on an IGX node. On a BPX node, only Transmit Trunk Rate is available. These parameters let you configure lower rates than the maximum line rate for the trunk type. If you adjust a rate, you need to do this at both ends of the trunk. For example, if RCV Trunk Rate on an IGX is 40,000 packets per second (pps), Transmit Trunk Rate on the far end must be 20,000 cells per second (cps). The typical relationship between pps and cps is two FastPackets for each cell.
The default value for Transmit Trunk Rate is the maximum rate for the back card type. You can reduce this rate to any number of cells per second that is less than or equal to the physical port rate. If E3 or T2 is selected, the bandwidth is reduced from the T3 rate.
Note You can configure the Transmit Trunk Rate parameter, which indicates the trunk load, by using the cnfrsrc command on BXM cards. On both IGX and BPX nodes, the trunk load displays in cps (cells per second), and the value is displayed in brackets on the first line of the cnftrk display.
On the cnftrk screen, the Transmit Rate and Transmit Load are always displayed in cps (cells per second). (The Transmit Load displays in brackets above the Transmit Rate field, for example, TRK 13.1.1 Config T3 [2867 cps].) Because switch software performs an internal conversion from DS0s to cells for the receive rate, this receive rate dictates the transmit load at the other end of the trunk, and vice versa. Because the Transmit Load (in cps) may not fit into the full DS0, the resulting number that appears in the Transmit Load field (for example, [2867 cps], could be truncated. For example, if you were to change the Transmit Rate on a routing trunk from 96000 to 104268, cnftrk will prompt you to enter a Transmit Rate of 0-104268, and will accept 104268, but it may assign a value of 104150 instead of 104268. The Transmit Load would be the same, for example, 104150 cps, regardless of whether the user configured the Transmit Rate as 104268 or 104269 or 104270.
This shows how the transmit rate is calculated internally by switch software:
1 DS0 = 64000 bits/sec
or
DS0 = 8 bits x 8000 samples/sec = 64000 bits/sec
1 cell long unit = 424 bits/sec
therefore:
Number of cells per second (cps) = DS0 * 8000 / 53 bytes per ATM cellFor any user-provided Transmit Trunk Rate value in T1 cells per second (cps).
Rcv Trunk Rate = T1 x 53 /8000 (in DS0)
(This is the actual value used for everything and dictates the Transmit Trunk Load value at the other end of the trunk.)
The conversion occurs again at the other end:
T2 = R1 * 8000 / 53 (in cps)
The Transmit Load number displayed in brackets is the same, that is, 104150 cells per second, whether the user has given the Transmit Rate as 104268 or 104269 or 104270.
Receive and Transmit Rates on Virtual Trunks
The implementation of XMT Trunk Rate on a virtual trunk differs from the implementation on a physical trunk. On a physical trunk, XMT Trunk Rate limits the rate at which the back card physically generates cells. For a virtual trunk, XMT Trunk Rate does not limit the rate at which the back card generates cells: the line rate stays at the maximum for the line type. However, XMT Trunk Rate is the maximum transmission rate allowed on a virtual trunk.
The provider of the virtual trunk service assigns the value for XMT Trunk Rate. You must have this provider-assigned value for XMT Trunk Rate and enter it when you use cnftrk.
The total bandwidth of all the virtual trunks in one port cannot exceed the maximum bandwidth of the port. The trunk loading (load units) is maintained per virtual trunk, but the cumulative loading of all virtual trunks on a port is restricted by the transmit and receive rates for the port.
ILMI Neighbor Discovery on Virtual Trunks
Starting with Release 9.3.10, you can configure the ILMI protocol to run on the interface card (BXM and UXM) or on the controller card (BCC and NPM). The ILMI Neighbor Discovery feature is available for use on virtual trunks on the BXM card and UXM card. This feature enables a network management system (NMS), such as Cisco WAN Manager or CiscoWorks 2000, to discover other attached ATM devices, such as Cisco ATM routers or switches. The attached devices also must support ILMI Neighbor Discovery for this feature to work.
When ILMI Neighbor Discovery is enabled on a virtual trunk, the BPX or IGX and the attached ATM device exchange their management IP addresses and other interface information using the ILMI protocol. The exchanged information consists of the following:
•atmfMyIfName: physical interface name
•atmfMyIfIdentifier: Interface identifier
•atmfMyIpNmAddress: Management IP Address, either the LAN IP or network IP
•atmfMySysIdentifier: System Identifier, a 6-byte string read from the BPX NOVRAM, or if not available, the default value is "000001"
The management IP address is used by the NMS application to access the BPX, IGX, or the ATM device. The management IP address can be either the LAN IP address or network IP address configured for the BPX or IGX node. Use parameter option 56 (BXM) or 53 (UXM) from the cnfnodeparm SuperUser command to configure the ILMI management IP address. Enter 0 for LAN IP address, or 1 for network IP address. The default is the network IP address for the BPX and IGX.
Once the parameter is set in cnfnodeparm, you enable the ILMI Neighbor Discovery feature by using the cnftrk command. Use the parameter ILMI Run On The Card for the UXM, and Protocol By The Card for the BXM.
You use the dspnebdisc command to display all the neighbor's information discovered by the BPX or the IGX via the ILMI Neighbor Discovery procedure.
IMA-Compliant Trunk Configuration
The cnftrk command has a parameter that lets you add or delete physical lines of an existing IMA group (IMA Group member parameter). You are prompted to enter the physical lines. When you add or delete a physical link, these rules are enforced:
•You cannot delete primary links.
•The total number of physical links in the group must be greater than or equal to the number of retained links. You will be prompted to decrease the number of retained links, if necessary.
•The bandwidth of the deleted physical link will be subtracted from the trunk's Trunk Transmit Rate only. The trunk's Trunk Receive Rate is unaffected. If the Trunk Receive Rate needs to be dropped down, you will be prompted to do this first in a separate operation. You will be warned that connection reroutes may occur.
Note The above functional characteristics apply only to the UXM Firmware Model M, which supports the ATM Forum IMA-Compliant protocol. If a card has UXM Firmware Model A, which supports the Cisco Proprietary protocol, the IMA trunk functions as it did in Release 9.1. For example, you will not be able to add or delete physical links of an existing IMA group.
Primary Link—In an IMA group, you must select one of the physical links to be a primary link. This primary link number is used to refer to this IMA group or trunk. You can use cnftrk to add additional links to the group or delete existing links.
When deleting existing links from an IMA group, you cannot delete the primary link. You must first deactivate the trunk using deltrk, then use dntrk to remove the primary link.Refer to 9.2 release notes for up-to-date feature support and system requirements.
Physical Lines Comprising an IMA Group
In Release 9.1, it was a requirement that the IMA group had to consist of consecutive physical lines. In this release, you can define an IMA trunk consisting of non-consecutive physical lines. In addition, you can change the group member by deleting a physical line from an existing IMA trunk.
Use the following syntax to specify an IMA group on a UXM trunk:
•uptrk slot.group_member.vtrk
where:
slot is the slot number
group_member is a set of physical lines composing an IMA group. You can specify the member in an expression consisting of the primary link followed by a, or - and additional physical links.
vtrk is the optional virtual trunk number. If at least one virtual trunk already exists on this port, you only have to specify the primary link as the group_member.
For example, 9.1-4 defines trunk 9.1 to consist of four physical links, that is, 1, 2, 3 and 4, where physical link 1 is the primary link. (This example is compatible with Release 9.1.)
For example, 9.1-3,5 defines trunk 9.1 to consist of four physical links, that is, 1, 2, 3 and 5 where physical link 1 is the primary link.
For example, 9.5-7,2-3 defines trunk 9.5 to consist of five physical links, that is, 2, 3, 5, 6 and 7 where physical link 5 is the primary link.
For example, 9.8,2,4,6 defines trunk 9.8 to consist of all even number of physical links where physical link 8 is the primary link.
Subrate and Fractional Trunk Configuration
For FastPacket trunks, which the NTC and NTM front cards support, you can configure the Subrate interface and Subrate data rate fields only if the back card is a BC-SR. The interface types for a subrate trunk are:
•V.11
•X.21
•V.35
•EIA/TIA-449
Set the data rate to match the subrate facility within the range 64 Kbps-1.920 Mbps.
The DS0 map is used to define fractional E1 and T1 trunks. It consists of a repeating set of specifications in the form:
<x[-y[a]]>
where
"x" and the optional "y" are DS0 numbers 0-23, and
the optional "a" indicates alternating.The value of "y" must be greater than the value of "x." The values of both "x" and "y" cannot be less than 0 or greater than the maximum number of DS-0s for the line type. In the DS0 map for unframed E1, use 0-31. For framed E1, use 1-31. For 30 DS-0 E1, use 1-15, 17-31.

cnftrkalm (configure trunk alarms)
Configures trunk alarm reporting. When trunks are upped and added to the network, alarm reporting automatically is enabled. The cnftrkalm command lets you disable alarms on a trunk. Disabling alarms may be useful, for example, for trunks that are connected to the node but not yet in service or if the node is experiencing occasional bursts of errors but is still operational.
When the alarms are enabled, they cause an alarm output from the DTI Group Alarm Connector (if present) and an alarm indication on the Cisco WAN Manager terminal.
A virtual trunk also has trunk port alarms that are shared with all the other virtual trunks on the port. These alarms are cleared and set together for all the virtual trunks sharing the same port.
Statistical alarms are provided on cell drops from each of the Advanced CoS Management queues. These alarms are maintained separately for virtual trunks on the same port.
On an IGX node, enabled alarms cause an output from the ARC or ARM card or an indication to Cisco WAN Manager.

Trunk Alarms
Table 3-44 shows physical and logical trunk alarms, with the alarm type, the physical interface type, and whether the alarm is a logical, statistical, or integrated alarm.
Statistical alarms are provided on cell drops from each of the Advanced CoS Management queues. These alarms are maintained separately for virtual trunks on the same port.
A virtual trunk also has trunk port alarms that are shared with all the other virtual trunks on the port. These alarms are cleared and set together for all the virtual trunks sharing the same port.
IMA physical line alarms are a special case. Each IMA trunk port has a configurable number of retained links. If the number of non-alarmed lines is less than the number of retained links, the logical trunks on the IMA trunk port are placed into major alarm.
For example, suppose there are IMA virtual trunks 4.5-8.2 and 4.5-8.7. Further, the number of retained links on 4.5-8 has been configured to 2. If 4.5 and 4.6 go into LOS, physical line alarms are generated for these 2 physical lines. The logical trunks 4.5-8.2 and 4.5-8.7 do not go into alarm because the two retained links are still healthy. In this situation, the bandwidth on the logical trunks is adjusted downwards to prevent cell drops, and the connections on those trunks are rerouted. If a third line goes into alarm, the logical trunks are then failed. See Table 3-45 for a list of physical and trunk alarms that are supported on IMA lines.
Example
Disable trunk alarms on trunk 7.

cnftrkparm (configure trunk card parameters)
Sets specified trunk parameters for these front cards:
•UXM/UXM-E
•AIT
•NTC
•NTM
•BNI
•BXM/BXM-E
Use the cnftrkparm command to optimize a network for particular traffic mixes. Use this command to configure any of the trunk-specific parameters associated with a trunk card. It applies to either a FastPacket trunk or a ATM trunk.
For ATM trunks, cnftrkparm applies to both physical and virtual trunks. BXM and UXM virtual trunks have the same configuration parameters for queues as physical trunks.
The integrated alarm thresholds for major alarms and the gateway efficiency factor is the same for all virtual trunks on the port. Note that BNI VTs are supported by a single queue and do not support configuration of all the OptiClass queues on a single virtual trunk.
You can also use this command to reconfigure trunk queue depths to meet the CEPT requirement for a maximum end-to-end delay of 10 milliseconds. For this purpose, enter:
cnftrkparm <trunk number> <parameter index> <parameter value>
where:
trunk number specifies the trunk.
parameter index is 2 (which corresponds to the NTS queue).
parameter value is 7 (which is the maximum allowable queue depth).When the system receives this command and a trunk number, it displays the configurable parameters with an index number for each. The parameters vary with the trunk type, as the subsequent figures and tables show.
Configuring Trunk Queues Used by Real-Time VBR and Non-Real-Time VBR Connections
Qbin values on both ports and trunks used by rt-VBR connections and nrt-VBR connections can be configured separately. (To configure Qbin values on ports, use cnfportq.)
The rt-VBR traffic type (or connection class) is supported on the IGX UXM and BPX BXM, ASI, and BNI cards. However, the rt-VBR class of service is not supported for MGX 8850 or MGX 8220 interface shelves.
A rt-VBR connection uses the rt-VBR queue on a trunk. It shares this queue with voice traffic. The rt-VBR and voice traffic shares the default or user-configured parameters for the rt-VBR queue. These parameters are queue depth, queue CLP high and CLP low thresholds, EFCI threshold, and queue priority.
A nrt-VBR connection uses the nrt-VBR queue on a trunk. The configurable parameters are queue depth, queue CLP high and CLP low thresholds, EFCI threshold, and queue priority.
You can configure the Qbin values separately for rt-VBR and nrt-VBR classes on trunks using the cnftrkparm command. For rt-VBR, the cnftrkparm command configures Q-depth rt-VBR and Max Age rt-VBR. For nrt-VBR, the cnftrkparm command configures Q-depth nrt-VBR, Low CLP nrt-VBR, and High CLP nrt-VBR.
For information on configuring port queues used by rt-VBR and nrt-VBR connections, see the cnfportq command.

Physical and Virtual Parameters Configurable with cnftrkparm
All virtual trunks on a BNI card are supported by a single queue; therefore, you cannot configure all the Advanced CoS Management queues on a single virtual trunk.
The UXM and BXM share the same queueing architecture. The egress cell traffic out a port is queued in two stages. First they are queued per virtual interface (VI), each of which supports a virtual trunk. Within each virtual interface, the traffic is queued according to its normal Advanced CoS Management traffic type. In other words, voice, Time-Stamped, Non-Time-Stamped, High-Priority, BData, BDataB, CBR, rt-VBR, nrt-VBR, and ABR traffic is queued separately.
The overall queue depth of the virtual interface is the sum of all the queue depths for all the available queues. Since each virtual trunk occupies one virtual interface (VI), the overall queue depth available for the virtual trunk is that of its VI. You do not configure the virtual interface directly, however, you use the cnftrkparm command to configure the queues within the virtual trunk.
Although the traffic consists of Frame Relay in cells, the traffic can pass through a BPX node. Therefore, the Bursty Data queues exist in the BPX node.
BXM and UXM virtual trunks have all the configuration parameters for queues that physical trunks have. The integrated alarm thresholds for major alarms and the gateway efficiency factor is the same for all virtual trunks on the port. Note that BNI virtual trunks are supported by a single queue and do not support configuration of all the Advanced CoS Management (formerly OptiClass) queues on a single virtual trunk.
Table 3-47 provides a list of physical and virtual parameters that you can configure using cnftrkparm. X in the table indicates that the parameter is configurable. X* in the virtual trunk column indicates the parameter is a physical parameter, and changing the value for one virtual trunk on the port will automatically cause all virtual trunks on the port to be updated with the same value.

cnftrkstats (configure trunk statistics collection)
Configures collection of Qbin statistics for a selected trunk.
You can enable collection of Qbin statistics collected by the BPX and IGX. Qbin statistics are Cells Served, Cells Discarded, and Cells Received.
•UXM and BXM Qbins 1-9 on Automatic Routing Management trunks.
•BXM qbins 0-3, 9 on Automatic Routing Management ports.
•UXM qbins 2,3, 7-9 on Automatic Routing Management ports.
•UXM and BXM Qbins 10-15 on VSI ports and trunks.
All other Qbins are unused, and the switch does not provide statistics for them. Also starting in switch software release 9.3.10, the switch provides the collection of Qbin Cells Discarded statistics via SNMP for the above mentioned Qbins.
The cnftrkstats command is primarily a debug command. It configures the collection of statistics for a physical or virtual trunk. After displaying all statistic types for the trunk, the system prompts for "statistic type." Enter the index number associated with the statistic.
Not all types of statistics are available for all lines. Unavailable selections appear in half-tone. Table 3-48 lists the types of statistics that are configurable for FastPacket T1 trunks and ATM T3 trunks. The subsequent figures show the screens associated with T1 packet trunks and T3 ATM trunks.

cnftstparm (configure card test parameters)
Sets parameters for the internal diagnostic self-tests that you can perform for each card type in the node.
Upon receiving this command, the system displays a two-page screen illustrating each of the various card types equipped in the node along with their self-test parameters.
Each card has two tests run on standby cards:
•Diagnostic self-test
The self-test affects the normal operation of the card.•Background test
The background test can execute while the card is carrying traffic.Only background tests are executed on active cards.
Here are the configurable test parameters for each card type:
•Frequency for Test Execution (sec)
•Enable/Disable Self-Test (e or d)
•Self-Test Failure Increment
•Self-Test Failure Threshold
•Time-out For Self Test (sec)
•Enable/Disable Background Test (e or d)
•Background Test Failure Increment
•Background Test Failure Threshold
Universal Router Module
With Release 9.3.20, the IGX 8400 supports the Universal Router Module (URM). The URM provides IOS-based voice support and basic routing functions. The URM is a combination of a URM front card and a 2FE2V back card. The URM hardware consists of an embedded UXM that provides the ATM interface to the IGX network and an embedded IOS-based router. The embedded UXM is based on UXM-E hardware. It is logically a one-port UXM without physical interfaces and provides functionality similar to the UXM/UXM-E modules in the IGX.
The URM supports card self-test and background test. Use the cnftstparm command to enable, disable, or configure the self-test and background test on the URM. The tests apply only to the embedded UXM side of the card.

cnfvchparm (configure voice channel parameter)
Modifies CVM or CVM voice channel parameters for:
•Voice Activity Detection (VAD)
•Background noise injection
•VF channel loss
•Echo suppression
•Modem detection
Different versions of firmware for the CVM present different ways of specifying the level of background noise you can select to cover awkward periods of silence at the ends of voice connections. For cards with Model A firmware, you specify the actual level in dBm (deciBels) or dBrnC0. For Model A cards, you can specify the noise levels with a granularity of 0.1 dBm or dBrnC0. For cards with Model B firmware, you enter a number that maps to a noise level.
After you enter cnfvchparm, the system displays "Enter channel(s)." After you enter the parameters, the system requests confirmation by displaying "Reconfigure active CDP channels? (y/n)."
Without the cnfvchparm command, the other ways to reconfigure channels are
•By switching cards
•By deleting then re-adding connections

cnfvchtp (configure interface type for voice channels)
Configures an interface signaling type for a voice channel. Most standard signaling types are maintained by the node, but you may build a custom template.
If you enter the cnfvchtp command without a specific interface number, the system will present you with a list of valid interface types and their associated on-hook and conditioning information.
To assign an interface type (and its associated on-hook and conditioning information) to the channel or set of channels, enter the number of the desired interface type. Type "1" requires user configuration. Interface type is ignored for "d" type connections.

cnfvsiif (assign a service class template to an interface)
Assign a service class templates (SCT) to an interface.
Use the dspvsiif command to display a service class template assigned to an interface, as well as display a summary of the resources allocated to the VSI partition on a given interface.
A default service template is assigned to a logical interface (VI) when you up the interface by using upport and uptrk.
For example:
•uptrk 1.1
•uptrk 1.1.1 (virtual trunk)
•upln 1.1 and upport 1.1
This default template (MPLS1) has the identifier of 1. You can change the service template from service template 1 to another service template by using the cnfvsiif command. The dspvsiif command allows you to display the template associated with the interface. For example:
•cnfvsiif 1.1 2
•cnfvsiif 1.1.1 2
•dspvsiif 1.1
•dspvsiif 1.1.1
Note Only MPLS1 (template 1) may be used with IGX.
Syntax
cnfvsiif <slot.port.vtrk> <tmplt_id>
Parameters
Parameter Description<slot.port.vtrk>
Specifies the card slot and port number and virtual trunk.
<tmplt_id>

cnfxmtsig (configure transmit signaling)
Allows the node to pass A, B, C, and D channel signaling bits through unchanged, or to invert, or hold them at a given value for a CDP or CVM line. It affects signaling bits in the transmit direction (to the PBX or channel bank) in an E1 system. The command configures the transmit signaling. Channel signaling bit options are T (transparent), 0, 1, or I (invert). If signaling is set to "not used" (-) by cnfchtp, the following is maintained: A=1, B=1, C=0, D=1.
Syntax
cnfxmtsig <channel(s)> <[A/]Conv> <[B/]Conv> <[C/]Conv> <[D/]Conv>
Parameters
