ATM Connections

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.

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.

Summary of Commands

Table 9-2 shows the name of each ATM connection command and starting page of its description.

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

• Flow diagrams showing the sequence of parameter prompts for each connection type

  • Figure 9-1 shows the prompt sequence for CBR connections.

  • Figure 9-2 shows the prompt sequence for VBR connections.

  • Figure 9-3 shows the prompt sequence for ATFR connections.

  • Figure 9-4 shows the prompt sequence for ATFST connections

  • Figure 9-5 shows the prompt sequence for ABRSTD connections.

  • Figure 9-6 shows the prompt sequence for ABRFST connections.

  • Figure 9-7 shows the prompt sequence for UBR connections.

• A table that names each type of policing

• A table showing each connection parameter, possible values, and defaults

• 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.

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.
