CFM Commands
Command Usage
•
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
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.
