This chapter describes the ATM commands that activate and configure ATM connections as well as statistical reporting for these connections at an ATM UNI in a BPX or IGX node. You can add ATM connections to an ASI or BXM in a BPX node or to an ALM/A in an IGX node. Table 9-1 lists the ATM UNI 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.

ATM UNI Cards

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 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 upline, upport and cnfport commands, 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 or a port-mode BXM 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 addcon command for ATM adds any one of the following types of ATM connections:

Constant Bit Rate (CBR)
Variable Bit Rate (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)
Unspecified Bit Rate (UBR)

This description has the following explanations in the form of figures and tables

A table with a brief definition of each connection parameter
Example screens from the command line interface

For detailed descriptions of the connection types, traffic classes, policing, and ATM-related topics, refer to the Cisco BPX 8600 Series Reference, the Cisco WAN Switching System Overview, and the ATM Forum specifications.

The node on which addcon executes is the "owner" of the connection. Connection ownership is important because 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.

The parameter prompts depend on the connection type. The figures on this and the following pages are flow diagrams showing the sequence of possible parameter prompts according to the connection type. The flow diagrams begin at the point after you have entered the remote node name and VPI and VCI (which are common parameters). The subsequent tables define the parameters and list the defaults and ranges for each parameter.

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.

Before a connection is added, the proposed connection appears on the screen with a prompt for confirmation. After addcon executes, the system software automatically routes the connection.

Table 9-3 contains descriptions of the ATM parameters that appear on screen. Table 9-4 gives the defaults, ranges (or values), and applicable connection type (marked with an X) for each parameter. Table 9-5 gives a shorthand definition of each type of traffic policing. In Table 9-5, note that VBR.1, VBR.2, VBR.3, CBR.1, UBR.1, and UBR.2 are ATM Forum standards for traffic policing. The columns in Table 9-5 indicate the actions involved with each policing type. For descriptions of the traffic types, connection types, and traffic policing, refer to the Cisco BPX 8600 Series Reference and the Cisco WAN Switching System Overview. The preceding flow diagrams help clarify the information in the forthcoming tables. The remaining parts of this description contain attributes and screen examples.

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 or OC12/STM4, as the text shows.

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 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` connection* (so the vci has no meaning 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 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 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).
connection class	Specifies one of the following connection types: VBR, UBR, CBR, ATFST, ATFR, ATFX, ATFT, ABRSTD, or ABRFST. 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 (Figure 9-1 through Figure 9-7). For a definition of each class, refer to the Cisco WAN Switching System Overview. The option for choosing a class `number` is also available. The class is a `template` for a connection type. The class 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.
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 time scale over which the PCR is policed.
FBTC (AAL5 Frame Base Traffic Control)	Enables the possibility of discarding a whole frame rather than a single, non-compliant cell. FBTC used to set the Early Packet Discard bit at every node along a connection.
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.

VC QDepth	The depth of the queue VC QDepth.
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.
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.
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.
IBR	Initial Burst Size: the maximum burst size a source can initially transmit after an idle period. IBR applies to only BXM cards.
ADTF (ATM Forum TM 4.0 term)	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.)

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, BXM, or UXM card slot and port number.
nni/uni	Specifies whether the cell header format is NNI or UNI. UNI is the default.
axis	Specifies MGX 8220 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 ILMI protocol, or no specified protocol. No specified protocol is the default.
%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)

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 ILMI protocol, or no specified protocol. No specified protocol is the default.

%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)

cnfportq

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.
