Troubleshooting ATM Router Module

Connections

This chapter provides troubleshooting information about connectivity and performance problems in the

ATM router module (ARM) on the Catalyst 8540 CSR, Catalyst 8510 MSR, and LightStream 1010 ATM

switch routers, and the enhanced ATM router module for the Catalyst 8540 CSR. The ATM router

module allows you to integrate Layer 3 switching with ATM switching on the same switch router.

Note For complete descriptions of the commands mentioned in this chapter, refer to the

ATM Switch Router Command Reference. For hardware installation and cabling instructions, refer to

the ATM and Layer 3 Port Adapter and Interface Module Installation Guide.

Note The LightStream 1010 system software image does not include support for the ATM router module

or Layer 3 features. You can download the Catalyst 8510 MSR image to a LightStream 1010 ATM

switch router that has a multiservice ATM switch processor installed.
