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.

Encapsulation(s):AAL5, PVC mode
10 maximum active VCs, 1 current VCCs
VC idle disconnect time:300 seconds
Last input 01:16:31, output 01:16:31, output hang never
Last clearing of "show interface" counters never
Input queue:0/75/0 (size/max/drops); Total output drops:0
Queueing strategy:Per VC Queuing
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
