A link trace message is a multicast CFM frame initiated by a MEP, and

forwarded from MIP to MIP, with each MIP generating a link trace reply,

up to the point at which the link trace message reaches its destination

or can no longer be forwarded.

Use this command to enable the link trace cache to store the results of

link trace operations initiated on this device. Use the

ethernet cfm

linktrace

command to transmit a link trace message.

Link trace responses are returned from each MIP along the path and

from the target MEP. Information stored in the cache includes the

maintenance domain name, MA name, MEPID, sequence number, and

TTL value.
