ATM Troubleshooting Commands

This command sends end-to-end OAM F5 packets, which are echoed back by the aggregator.

show interface Command

Use the show interface command to display the status of all physical ports (Ethernet and ATM) and

logical interfaces on the router. Table 12-1 describes messages in the command output.
