Troubleshooting Frame Relay PVC, Terminating on ATM Router Module
Step 7 Verify the contents of the Type field is arm_port. If not, you might have configured the wrong module.
Step 8 Verify the Status field is UP. If it is not, check the configuration of both ATM router module and Frame
Relay interfaces.
Step 9 Verify the contents of the connection-type field is PVC. If it is not check the configuration.
Step 10 Verify that the Rx and Tx counters are incrementing. Check the display numerous times to verify the
interface is receiving and sending frames.
Step 11 Enter the show controllers command with the ATM router module interface to display the physical
status of the interface.

Step 12 Enter the show controllers command with the E1 or T1 interface to display the physical status of the
interface.
Switch# show controllers e1 1/0/1
E1 1/0/1 is up.
