This command is automatically issued when the
ethernet cfm global command is issued.
Step 8
ethernet cfm traceroute cache
Example:
Router(config)# ethernet cfm
traceroute cache
Enables caching of CFM data learned through traceroute
messages.
Step 9
ethernet cfm traceroute cache size
entries
Example:
Router(config)# ethernet cfm
traceroute cache size 200
Sets the maximum size for the CFM traceroute cache
table.
Step 10

are retained.
Step 11
snmp-server enable traps ethernet cfm
cc [mep-up] [mep-down] [config]
[loop] [cross-connect]
Example:
Router(config)# snmp-server enable
traps ethernet cfm cc mep-up mep-down
config loop cross-connect
Enables SNMP trap generation for Ethernet CFM
continuity check events.
Step 12
snmp-server enable traps ethernet cfm
crosscheck [mep-unknown]
[mep-missing] [service-up]
Example:
Router(config)# snmp-server enable
traps ethernet cfm crosscheck
mep-unknown
Enables SNMP trap generation for Ethernet CFM
continuity check events in relation to the cross-check
operation between statically configured MEPs and those
learned via CCMs.
