Configuring LT on MEPs

LT can trace the path between the specified MEP and the target MEP, and can also locate link faults by
sending LT messages automatically. The two functions are implemented in the following way:
To implement the first function, the specified MEP first sends LTM messages to the target MEP.
Based on the LTR messages in response to the LTM messages, the path between the two MEPs
can be identified.
In the latter case, after LT messages automatic sending is enabled, if a MEP fails to receive the
CCMs from the remote MEP within 3.5 sending intervals, the link between the two is considered
faulty and LTMs (with the remote MEP as the destination and the TTL field in the LTMs set to the
maximum value 255) will be sent out. Based on the LTRs that echo back, the fault source can be
located.
