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 information on installing the Catalyst 5000 family ATM fabric integration module, refer to the Catalyst 5000 Family Module Installation Guide.|
|Note For syntax and usage information for the commands used in this chapter, refer to the Command Reference publication for your switch.|
This chapter consists of these sections:
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 OC-12 interface on a LightStream 1010 port adapter and is configured from the LightStream 1010 command-line interface.
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.
These guidelines apply when using the ATM fabric integration module:
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.

These sections describe how to configure the ATM fabric integration module:
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 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:
Enter configuration mode.
Select the ATM interface.
interface atm card/subcard/port
Disable atm auto-configuration.
no atm auto-configuration
Configure the interface.
atm nni | uni | pvc
Exit configuration mode.
This example configures the external interface as a network node interface and displays the configuration:

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, see the following sections:
The following commands are not available on the ATM fabric integration module:
In addition, the show controller command output does not show PHY error counters for the internal ATM port.
On the LightStream 1010 side, the internal interface functions similarly to an OC-3 ATM interface on a LightStream 1010 ATM port adapter. 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.
