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

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.

Example
This example enables link trace caching.

Console(config)#ethernet cfm linktrace cache

ethernet cfm linktrace cache hold-time

This command sets the hold time for CFM link trace cache entries. Use the no form to restore the
default setting.
