Configuring the ATM Fabric Integration Module

This chapter describes how to configure the ATM fabric integration module. The ATM fabric integration module is supported on the Catalyst 5500 series switches only.

Note For complete information on installing the Catalyst 5000 family ATM Fabric integration module, refer to the Catalyst 5000 Family Module Installation Guide.

Note For complete syntax and usage information for the commands used in this chapter, refer to the Command Reference for your switch.

This chapter consists of these sections:

Understanding How ATM Fabric Integration Works

The ATM fabric integration module seamlessly integrates the switching fabrics of a Catalyst 5500 series switch and a LightStream 1010 ATM switch installed in the bottom slots of the Catalyst 5500 chassis.

The module consists of one external LightStream 1010 OC-12 ATM interface and one internal interface to the LightStream 1010 switching backplane. The external OC-12 ATM interface operates exactly as any an OC-12 interface on a LightStream 1010 port-adapter module (PAM) and is configured from the LightStream 1010 CLI.

Communication between the Catalyst 5500 series switch backplane and the LightStream 1010 ATM switch backplane occurs across the internal interface. You must configure the interface from both the ATM module CLI and the LightStream 1010 CLI.

ATM Fabric Integration Hardware and Software Restrictions

These guidelines apply when using the ATM fabric integration module:

You must use Catalyst 5000 family supervisor engine software release 4.3(1) or later on the Catalyst 5500 series switch.
You must use Catalyst 5000 family ATM software release 11.3(5)WA4(8a) or later on the ATM fabric integration module.
A LightStream 1010 ATM Switch Processor (ASP) running LightStream 1010 software release 12.0(1)WA5(5) or later must be installed in slot 13 of the Catalyst 5500 switch. If no ASP is installed, the fabric integration module will not function.
You must install the ATM fabric integration module in slots 9-12 of the Catalyst 5500 series switch.

Default ATM Fabric Integration Configuration

The external ATM interface of the fabric-integration module has the same default configuration as any LightStream 1010 OC-12 ATM interface. For information on the OC-12 ATM interface default configuration, refer to the LightStream 1010 ATM Switch Configuration Guide publication.

Table 6-1 shows the ATM fabric-integration module internal interface default configuration on the Catalyst 5500 side.

Configuring the ATM Fabric Integration Module

These sections describe how to configure the ATM fabric integration module:

Configuring the External OC-12 ATM Interface

You configure the external OC-12 interface on the ATM fabric integration module from the LightStream 1010 CLI. The following example shows how to configure the external interface as a network node interface (NNI), but the external interface on the ATM fabric integration module supports all the network connections configurable on a LightStream 1010.

Note For complete information on configuring ATM interfaces, refer to the LightStream 1010 ATM Switch Configuration Guide.

To configure the external OC-12 interface on the ATM fabric integration module, perform these tasks from the LightStream 1010 CLI:

Task Command

Step 1

Enter configuration mode.

configure terminal

Step 2

Select the ATM interface.

interface atm card/subcard/port

Step 3

Disable atm auto-configuration

no atm auto-configuration

Step 4

Configure the interface.

atm nni | uni | pvc

Step 5

Exit configuration mode.

Ctrl-Z

	Task	Command
Step 1	Enter configuration mode.	configure terminal
Step 2	Select the ATM interface.	interface atm card/subcard/port
Step 3	Disable atm auto-configuration	no atm auto-configuration
Step 4	Configure the interface.	atm nni \| uni \| pvc
Step 5	Exit configuration mode.	Ctrl-Z

This example configures the external interface as a network node interface and displays the configuration:

ls1010-3#config term
Enter configuration commands, one per line.  End with CNTL/Z.
ls1010-3(config)#interface atm9/1/0
ls1010-3(config-if)#no atm auto-config
ls1010-3(config-if)#atm nni

Configuring the Internal ATM Port from the ATM Module CLI

On the Catalyst 5500 switch side, the internal interface functions similarly to the ATM ports on the Catalyst 5000 family ATM OC-3 LANE/MPOA modules. However, there is no PHY on the internal bridge port.

You can configure the internal ATM interface (interface ATM0) exactly as you configure any ATM interface on the Catalyst 5000 family LANE/MPOA modules. For information on configuring the ATM interface, refer to the following sections:

For information on configuring ATM LANE, see "Configuring ATM LAN Emulation."
For information on configuring MPOA, refer to the "Configuring the MPC" section and the "Configuring the MPS" section.

The following commands are not available on the ATM fabric integration module:

set clock
set sonet mode

In addition, the show controller command output does not show PHY error counters for the internal ATM port.

Configuring the Internal ATM Interface from the LightStream 1010 CLI

On the LightStream 1010 side, the internal interface functions similarly to an OC-3 ATM interface on a LightStream 1010 ATM port adapter module (PAM). However, there is no PHY on the internal bridge interface.

You can configure the internal ATM interface exactly as you configure any OC-3 ATM interface on a LightStream 1010 PAM. For information on configuring the LightStream 1010 ATM interface, refer to the LightStream 1010 ATM Switch Configuration Guide publication.
