Note that:
z
After LT messages automatic sending is enabled, if a MEP fails to receive the CCMs from the
remote MEP, the link between the two is regarded as faulty and LTMs will be sent out. (The
destination of the LTMs is the remote MEP, and the maximum value of TTL is 255.) Based on the
LTRs that echo back, the fault source can be located.
z
Once you disable LT messages automatic sending, the content stored in the buffer will be
removed.
