ATM Connections

ATM Connections


This chapter describes the ATM commands that apply to activating and configuring ATM connections and statistical reporting for these connections at an ATM UNI in a BPX or IGX node. You can add ATM connections to an ASI or BNI in a BPX node or to an ALM/A in an IGX node. Table 10-1 lists the ATM card combinations for BPX and IGX nodes. For details regarding ATM commands and other support on an MGX 8220 shelf, refer to the MGX 8220 documentation.

Setting Up an ATM Connection

To set up an ATM connection, perform the following steps:

Step 1   Activate a line with the upln command. Activation makes the line available for you to configure it and causes statistics gathering to begin. Subsequently, you can begin to add connections with addcon. You can verify activation with the dsplns command. (See the chapter titled "Setting Up Lines" for descriptions of upln and dsplns.)

Step 2   Activate the ATM port with the upport X.X command, where X.X is the slot and port (1-4) of the ATM card set.

Step 3   Use the cnfport command to establish the characteristics for the ATM port.

Step 4   If a suitable class is already configured, note its number and use this class when adding the ATM connection with the addcon command. (The dspcls command displays the parameters for each connection class. The cnfcls command allows an individual class to be modified.)

Step 5   Use the vt command to log in to the node at the remote end of the proposed ATM connection.

Step 6   At the remote node, use the upport and cnfport as listed in steps 1 and 2 to activate and configure the remote port.

Step 7   Use the addcon command at one end of the connection to activate the ATM connection.

Managing Bandwidth

There are a number of commands that assist in managing bandwidth to achieve satisfactory traffic patterns.

  • cnfpref

The configure preference command can be used to specify preferred routing for intra-domain connections. This command can be used to assist in balancing the load on the network's trunks.

  • dsprts, prtrts

The display and print routes commands can be used in conjunction with the cnfpref command to display the current connection routing information.

  • upcon, dncon

The up and down connection commands can be used to temporarily down connections, thus releasing bandwidth for other services. Often it is possible to down some voice connections to provide more bandwidth for data, frame relay, or ATM traffic.

Other Commands

The following commands may be useful for establishing connections.

  • delcon

Deletes a connection from an ATM line.

  • dspcons

Displays the connections on a specified ATM line.

  • dsplnutl

Displays the line utilization for an ATM line.

addcon

Establishes an ATM connection between the current node and one or more nodes in the network. You can add ATM connections at a UNI port on either an ASI in a BPX node or an ALM/A in an IGX node. When used with the syntax in this chapter, addcon adds either a standard ATM connection or an ATM-frame relay interworking connection. For a description of the addcon command as it applies to frame relay connections, voice connections, or serial data connections, refer to the chapter in this manual that describes the applicable traffic type. For descriptions of the ATM commands that operate on an MGX 8220 shelf, see the MGX 8220 documentation.

The node on which addcon executes is the "owner" of the connection. Connection ownership is important because automatic rerouting and preferred routing information for a connection is entered on the node that owns the connection. See the cnfpref and cnfcos descriptions for information on automatic rerouting.

The displayed parameter prompts depend on the connection type. Before the switch actually adds a connection, the proposed connection appears on the screen with a prompt for confirmation. After addcon executes, the system software automatically routes the connection.

The displayed parameter prompts depend on the connection type. Before the switch actually adds a connection, the proposed connection appears on the screen with a prompt for confirmation. After addcon executes, the system software automatically routes the connection. Figure 10-2, and Figure 10-3 are flow diagrams showing the sequence of possible parameter prompts according to the connection type and whether Usage Parameter Control (UPC) is enabled. The flow diagrams begin at the point after you have entered the local VPI and VCI, remote node name, remote VPI and VCI (or DLCI for service interworking), and con_type (VBR, CBR, ABR, ATFR, ATFST, ATFT, ATFTFST, ATFX, or ATFXFST). The subsequent tables define the parameters and list the defaults and ranges for each parameter. Refer to the Cisco WAN Switching System Overview and the ATM Forum specifications for more details on ATM parameters and concepts such as the leaky buckets for controlling cell admissions to the network.

A form of notation appears for some parameters that may need explanation. The notation is either (0), (1), or (0+1). 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. CDVT (0) means CDVT for cells with CLP=0. PCR(0) means PCR for cells with CLP=0. For a description of CLP and CDVT usage and policing concepts in general, refer to the Cisco WAN Switching System Overview and the ATM Forum specifications.

The following table contains descriptions of the ATM parameters that appear on screen. The subsequent table gives the defaults, ranges (or values), and granularity for each parameter. The last section contains screen examples. The preceding flow diagrams help clarify the information in these forthcoming sections.

Note If the description states the parameter is transmit/receive, the system is prompting for two values: one is for the transmit direction, the other for the receive direction. Also, not all parameters apply to OC3/STM1, as the text shows.

Table 10-3: addcon-Parameters
Parameter/Prompt Description

local 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. The vpi and vci ranges are:

The vpi range for a UNI connection is 0-255. The vpi range for an NNI connection is 0-1023

The standard range for a vci is 1-4095. On an ALM/A, the vci range is 0-255. The vci can be an asterisk (*) to indicate the connection is a virtual path, in which case the vci does not provide a distinction within the network.

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 ATM connection. The format is slot.port.vpi.vci. The vpi and vci ranges are as follows:

The vpi range for a UNI connection is 0-255. The vpi range for an NNI connection is 0-1023

The range for a vci is 1-4095. The vci can be an asterisk (*) to indicate the connection is a virtual path (the vci does not provide a distinction within the network).

For service interworking, the remote channel has the format slot.port.DLCI.

connection type

Specifies one of the following connection types:

VBR—Variable Bit Rate, applies to ATM-only connections added at the ASI.

CBR—Constant Bit Rate, applies to ATM-only connections added at the ASI.

ABR—Available Bit Rate, applies to ATM-only connections added at the ASI.

ATFR—Network interworking for a connection added to a BNI attached to an MGX 8220 shelf. The near-end frame relay card is the FRSM in the MGX 8220 shelf. The far-end is a UFM/FRM/FRP. The ATFR connection type directs the AIT, BTM, or ALM/B in the IPX or IGX node to perform network interworking on the connection.

ATFST—Network interworking for a connection added to a BNI attached to an MGX 8220 shelf. The near-end frame relay card is the FRSM in the MGX 8220 shelf. The far-end is a UFM/FRM/FRP. The ATFST connection type specifies ForeSight and directs the AIT, BTM, or ALM/B in the IPX or IGX node to perform network interworking on the connection.

ATFT—Service interworking in transparent mode: this connection type applies to connections with a frame relay endpoint and an ATM endpoint. You can add the connection at an ASI for standard ATM connections at the UNI or a BNI that connects to an ATM card in an MGX 8220 shelf. The endpoint cards must be capable of supporting service interworking. On the IGX node, the only card capable of supporting SIW is the UFM.


ATFTFST—Same as ATFT except that the connection also has ForeSight.

ATFX—Service interworking with translation of encapsulation protocols: this connection type applies to a connection that has a frame relay endpoint and an ATM endpoint. You can add the connection at an ASI for standard ATM connections at the UNI or a BNI with a segment terminating on an ATM card in an MGX 8220 shelf. The "X" ("translation") means the protocols for encapsulating headers are translated.

ATFXFST—Same as ATFX but with ForeSight.

The parameters that follow the con_type entry depend on the chosen connection type. Refer to the flow diagrams in Figure 10-1, Figure 10-2, or Figure 10-3.

The option for choosing a class number is also available. The class is a template for a connection type. This serves as an alternative to specifying each parameter for a connection type. To specify a connection class, enter a digit in the range 1-10. To see the parameter values for a class, use the dspcls commands. To customize any class template, use cnfcls.

ABR

T3/E3: Enables/disables ForeSight. Refer to the flow diagrams on the preceding pages for help with the following explanation:

If the connection type selected at the "connection class" prompt was VBR and ABR is enabled at this prompt, the connection type changes to ABR, and prompts for ABR parameters subsequently appear. On the other hand, if the selected connection type is ABR and ABR is disabled at this ABR prompt, the connection type changes to VBR, so only VBR parameters are requested.

PCR(0+1)

T3/E3: Specifies the transmit/receive Peak Cell Rate (PCR) for cells leaving the first leaky bucket on the ASI card with CLP(0+1). Applies to only CBR connections.

OC3 (STM1): Specifies the transmit/receive Peak Cell Rate (PCR).

The range is 10 cps up to the maximum line rate. (See table of defaults and ranges.)

UPC

T3/E3 or OC3 (STM1): Enables/disables Usage Parameter Control (UPC). With UPC, additional user-specified parameters become available for each connection type. Refer to the preceding flow diagrams to see the parameters available for each connection type. The system uses the default if no parameter change occurs. See next table for defaults.

FGCRA

T3/E3: Enables either the Frame-Based Generic Cell Rate Algorithm (FGCRA) or the standard GCRA (the default).

FGCRA controls automatic cell discarding (or tagging) of the remainder of a frame when one cell from the frame is non-compliant. FGCRA is a Cisco enhancement of the ATM-UNI Generic Cell Rate Algorithm (GCRA) for associating a cell with the frame from which it originated. Cisco supports configuration on a per-connection basis.

CDVT(0+1)

T3/E3 or OC3 (STM1): Specifies the transmit/receive Cell Delay Variation Tolerance (CDVT) for the first leaky bucket, which applies to cells with CLP(0+1). CDVT is the maximum time for accumulated violations of cell-arrival time parameters.

PCR(0)

T3/E3: Specifies the transmit/receive Peak Cell Rate (PCR) for cells leaving the second leaky bucket [CLP(0)] on the ASI card.

OC3 (STM1): PCR(0) not used by ASI-2 OC3 (STM1).

CDVT(0)

T3/E3: Specifies the transmit/receive Cell Delay Variation Tolerance (CDVT) for the second leaky bucket. The second bucket applies to cells with CLP(0). CDVT is the maximum time for accumulated violations of cell-arrival time parameters.

OC3 (STM1): CDVT(0) not used by ASI-2 OC3 (STM1) card.

SCR policing

T3/E3: Specifies the traffic policing for a VBR or ABR connection. The possible policing configurations are SCR policing of CLP (0+1) (which is selected as SCR#2), SCR policing of CLP(0) (which is selected as SCR#1), or SCR policing off (SCR#3). The SCR Policing parameter is not used by ASI-2 OC3 (STM1) card.

SCR

T3/E3: Sustainable Cell Rate (SCR) specifies a compliant cell rate threshold for transmit/receive. SCR is available with ABR and VBR connections and is less than or equal to the Peak Cell Rate (PCR). The ASI-2 OC3 (STM1) card does not use SCR policing.

MBS

T3/E3 or OC3 (STM1): The transmit/receive Maximum Burst Size for SCR policing.

CLP tagging

T3/E3 and OC3 (STM1): Enables/disables Cell Loss Priority (CLP) tagging. If CLP tagging is enabled, the CLP bit is set as a result of a UPC violation.

MCR

T3/E3: Specifies the transmit/receive Minimum Cell Rate (MCR) for ABR connections.

ICR

T3/E3: Specifies the transmit/receive Initial Cell Rate. ICR is the rate that occurs after a period of inactivity on an ABR connection. (This period is the value of ICR TO). The cell rate then goes up or down under the control of the ForeSight Rate Control Algorithm. The range is 0 cps through the line's maximum. The ICR default is a range under the control of the ForeSight Rate Control Algorithm. See also the descriptions of Rate Up and Rate Dn.

ICR TO

T3/E3: ICR timeout. Specifies a period of inactivity before a connection's cell rate is reset to the specified ICR.

Rate Up

T3/E3: Specifies the increment in cell rate when the rate goes up. This ForeSight Rate Up increment is in cells per second per adjustment.

Rate Dn

T3/E3: Specifies large reductions in the transmit/receive cell rate. This ForeSight Rate Down value is a percentage of the current rate.

Rate FastDn

T3/E3: Specifies a rate of decrease in the transmit/receive cell rate when ForeSight quickly adjusts the rate down. This value is a percentage of the SCR.

Minimum Adjust

T3/E3: Minimum Adjust Period specifies the interval before the ingress sends rate adjustments for ABR connections. This is the time period before either a rate adjustment is made or a message is sent that an adjustment is not necessary. It serves as a stand-in round trip delay until a true RTD is measured. Older software refers to this as Maximum Adjust Rate.

VC Qdepth

T3/E3: Specifies the maximum ABR VC queue depth for transmit/receive.

EFCI

T3/E3: The transmit/receive percent of ABR VC queue depth that causes EFCI to be set.

CLP Hi

T3/E3: Specifies a percent of the transmit/receive ABR VC queue depth. When a transmit/receive threshold is exceeded, the node discards cells with CLP=1 in the connection until the VC queue level falls below the depth specified by CLP lo.

CLP Lo

T3/E3: Specifies a percent of the transmit/receive ABR VC queue depth such that, when the VC queue level falls below this level, the node stops discarding CLP=1 cells.

IBS

T3/E3: Initial Burst Size (IBS) for transmit/receive. Applies to only ABR connections.

RM

T3/E3: Enables Resource Management cells to go to a port on an ASI. RM cells provide backwards congestion notification, which subsequently goes to external equipment. For BNI cards, leave RM disabled. In older software, the name of this parameter is BCM.

% Util

T3/E3: Specifies the percent of bandwidth utilization for a connection. The allocation of trunk bandwidth that is based on %util depends on the connection type, as follows:

For CBR, the default is 100%, and the bandwidth allocation is PCR(0+1) * %util.

For VBR, the default in the command prompt is the minimum of either 100% or 120(SCR/PCR). The bandwidth allocation is PCR(0+1) * %util.

For ABR, the default is 100%. The bandwidth allocation is MCR * %util.

addcongrp

Sets up a group to which ATM connections between the local node and a remote node are added. The connection group is a routing entity that is initially empty and to which individual connections (virtual circuits) are added using the grpcon command. Connections added to a group must be of the inter-node, non-bundled, ATM type. The connections must have the same routing parameters. These parameters include connection owner, class of service (COS), connection state, route restrictions, and ForeSight enable status.

Connection grouping permits an IPX or IGX node to have up to 1000 connections and a BPX node to have up to 5000 connections. A connection group may have up to 16 connections.

cnfcon

Configures the ATM bandwidth parameters for a specified connection. The initial cell rate (ICR) normally is set to the port speed. It may be lower if other constraints exist on the data generation rate. If ICR is too low, cells are dropped. If it is too high, bandwidth may be wasted unless ForeSight is used. Statistical reports are the best source of information for deciding what to adjust.

If the connection type includes ForeSight (abr enabled), the results of the last test round trip delay command (tstdelay) appear. Note that this is not the current RTD but the result of the last test that ran. Connection priority — high or low — is displayed for standard frame relay connections and ForeSight connections. Several checks are done on the parameters that specify bandwidth to assist users in efficient use of network bandwidth. The following messages describe the performance evaluation.

♦ 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 only, so the related operation continues. If an error message appears, the operation does not continue.

Parameter Description

slot.port

Specifies the ASI card slot and port number.

nni/uni

Specifies whether the cell header format is NNI or UNI.

axis

Specifies MGX 8220 shelf queue depth for each slot.

metro data cell header

Specifies whether the metro data cell header type is used.

shift h | n

Specifies whether a one-byte shift on the HCF field of the cell header occurs. 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:

Select H (the default) if the cloud includes non-Cisco WAN switching nodes or if only a physical trunk is configured for the ASI port.

Select N if virtual trunks are configured and the ATM cloud consists of Cisco WAN switching nodes only.

protocol

Specifies the use of either an LMI protocol, an protocol, or no specified protocol.

%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.

When this feature is disabled, the port queue bandwidth is calculated using the sum of the MCRs or PCRs for the connections terminating on the port. This is identical to the port queue bandwidth calculation prior to the implementation of the %util feature.

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)

dspportstats

Displays a summary of port statistics for the ATM port specified. These include the cell count in the transmit and receive directions, and error counts associated with the port. The display indicates the date and time that the statistics were cleared and the statistics collection time since the last clearance. Cells transmitted indicates the amount of data transmitted out the port to the user device. Cells received indicates the amount of data received from the user device at the port. Corrupted statistics result from channel/port loopbacks or port tests. A yes in this field indicates that such loopback or port test have occurred since the statistics were last cleared.

Parameter Description

interval

Specifies the refresh interval time for data. It can be specified between 1 and 60 seconds. The default interval is 1 seconds.

grpcon

Adds a connection to a group. Adding a connection to a group has two prerequisites:

No command exists to delete an individual connection from a group. Instead, the connection must be deleted (using delcon) then added again. The grpcon command can be used to add either a single connection or multiple connections. Using the optional channel ... channel parameter format, a range of 1 - 16 connections can be added to the group in one command. All connections in the group must be of the inter-node, non-bundled ATM type. They must also have the same endpoints, routing characteristics, and ForeSight enable status.

The first connection added to a group determines the routing characteristics of the entire group. All subsequent connections must match the first connection's characteristics of ownership, COS, routing state, routing restrictions, and ForeSight. Attempting to add a dissimilar connection results in an error message "mismatched connection/group" characteristic. For example, the ownership of both the connection group and the connection itself must be either local or remote. Non-connection parameters, such as fail state, loop state, and configuration, can be specified for an individual connection in the group after the connection has been added to the group.
