Configuration Example for Ethernet CFM (Double-Tagged Packets)
This example shows how to configure Ethernet CFM for double-tagged packets:
Router>enable
Router#configure terminal
Router(config)#ethernet cfm ieee
Router(config)#ethernet cfm global
Router(config-ecfm)#ethernet cfm domain customer level 7
Router(config-ecfm)#service customer1101 vlan 100 inner-vlan 30 direction down
Router(config-ecfm-srv)#continuity-check
Router(config-ecfm-srv)#interface gigabitethernet
0/2
Router(config-if)#ethernet cfm mep domain customer mpid 100 service customer1101
Router(config-if-ecfm-mep)#interface gigabitethernet 0/2.1101
Router(config-subif)#encapsulation dot1q 100 second-dot1q 30
Router(config-subif)#end
Verififying the Ethernet CFM Configuration for Double-Tagged Packets
Use the following commands to verify Ethernet CFM configured for double-tagged packets:
show ethernet cfm maintenance-points local
show ethernet cfm maintenance-points remote
ping ethernet mpid mpid-value domain domain-name service service-name cos value
traceroute ethernet mpid mpid-value domain domain-name service service-name
show ethernet cfm error configuration
Use the show ethernet cfm maintenance-points local command to view the local MEPs. The following is
a sample output of the show ethernet cfm maintenance-points local command:
Router#show ethernet cfm maintenance-points local
