Issuing CFM linktrace tests
Use the procedures in this section to issue CFM path trace messages and to discover the path
to a remote MEP or MIP.
Tracing the path to a remote MEP
Use the procedure in this section to discover the path to a remote MEP.
Procedure steps
1. To access test mode, enter:
2. To access the Ethernet OAM test mode, enter:
3. To access the CFM test mode for the MEP, enter:
4. To initiate the linktrace test for the MEP, enter:

Variable
Value
The short name of the MD.
The short name of the MA.
The numerical identifier for the MEP. Values
are in the range from 1 to 8191.
Enter either the remote MEP ID or the MAC
address of the host for the remote MEP.
The "time to live" value. Similar to the IPv4
TTL value, the CFM TTL value is
decremented by one unit on every hop. If the
TTL value drops to zero before the LTM
reaches its destination, the linktrace test
terminates. Enter a value from 1 to 255. The
default value is 64.
