Command Usage
◆
Before setting the cache size, the cache must first be enabled with the ethernet
cfm linktrace cache command.
◆
If the cache reaches the maximum number of specified entries, or the size is set
to a value less than the current number of stored entries, no new entries are
added. To add additional entries, the cache size must first be increased with this
command, or purged with the
clear ethernet cfm linktrace-cache command.
Example
This example limits the maximum size of the link trace cache to 500 entries.
Console(config)#ethernet cfm linktrace cache size 500
Console(config)#
ethernet cfm linktrace
This command sends CFM link trace messages to the MAC address of a remote MEP.

{ dest-mep destination - mpid | mac-address } | mac-address } md domain-name
ma ma-name [ ttl numbe r]
destination - mpid – The identifier of a remote MEP that is the target of the
link trace message. (Range: 1-8191)
