Command Modes Global configuration (config)
Command History
Usage Guidelines Before you can issue this command, you must have enabled traceroute caching using the ethernet cfm
traceroute cache command.
Entries in the traceroute cache table are single replies from remote devices—not the number of
operations on the device. In Cisco pre-Standard CFM Draft 1 when the maximum cache size is reached,
new replies cannot be added until you clear the cache or increase its size. In CFM IEEE 802.1ag Standard
when the maximum cache size is reached, the oldest traceroute operation is removed to make room for
a new traceroute operation.
Output of the show running all command displays “ethernet cfm traceroute cache size 100” when
traceroute cache is enabled and the default value of 100 is configured.
Setting the number of entries lower than the number of entries currently cached causes this command to
be rejected, and you are prompted to clear the traceroute cache.
entries Number of entries in the traceroute cache table, expressed as an integer in
the range of 1 to 4095. The default is 100.
