Configuration Examples for Ethernet OAM

Step 2
If the results of the ping ethernet cfm command show a problem with connectivity to the peer MEP, use the traceroute
ethernet cfm command to help further isolate the location of the problem as shown in the following example:
RP/0/RP0/CPU0:router#
Traceroutes in domain D1 (level 4), service S1
Source: MEP-ID 1, interface TenGigE0/0/0/2
================================================================================
Traceroute at 2009-05-18 12:09:10 to 0001.0203.0402,
TTL 64, Trans ID 2:
Hop Hostname/Last
--- ------------------------ ---------------------- ---------------------- -----
1 ios
0000-0001.0203.0400
2 abc
ios
3 bcd
abc
Replies dropped: 0
If the target was a MEP, verify that the last hop shows "Hit" in the Relay field to confirm connectivity to the peer MEP.
If the Relay field contains "MPDB" for any of the hops, then the target MAC address was not found in the bridge MAC
learning table at that hop, and the result is relying on CCM learning. This result can occur under normal conditions, but
it can also indicate a problem. If you used the ping ethernet cfm command before using the traceroute ethernet cfm
command, then the MAC address should have been learned. If "MPDB" is appearing in that case, then this indicates a
problem at that point in the network.
