To transmit link trace messages:
1. Click Administration, CFM.
2. Select Transmit Link Trace from the Step list.
3. Select an entry from MD Index and MA Index.
4. Specify the source MEP, the target MEP using either its MEP identifier or MAC address, and set

Transmitting Loop Back Messages
Use the Administration > CFM (Transmit Loopback) page to transmit Loopback Messages (LBMs).
These messages can be used to isolate or verify connectivity faults by submitting a request to a
target node (i.e., a remote MEP or MIP) to echo the message back to the source.
