Troubleshooting Frame Relay PVC, Terminating on ATM Router Module
Follow these steps to troubleshoot the Frame Relay PVCs terminating on the ATM router module:
Step 1 Enter the show running-config command to display the configuration of the Frame Relay serial
interface, and to confirm the ATM router module PVC configuration.
Switch# show running-config
Building configuration...

Step 2 Verify the number in the frame-relay pvc and service translation interface field is cross-connected to the
ATM router module.
Step 3 Enter the show interfaces serial command to check the status of the Frame Relay interface.
