Configuration Example for Ethernet CFM (Single-Tagged Packets)
This example shows how to configure Ethernet CFM for single-tagged packets:
Step 5
ethernet cfm domain domain-name level
value
Example:
Router(config)#ethernet cfm domain
customer level 7
Defines a CFM maintenance domain at a specified level,
and enters the Ethernet CFM configuration mode.
level can be any value from 0 to 7.
Step 6
service service-name vlan vlan-id
direction down
Example:
Router(config-ecfm)#service
customer1101 vlan 100 direction down
Enters the CFM service configuration mode.
vlan—Specifies the VLAN.
Step 7
continuity-check
Example:
Router(config-ecfm-srv)#continuity-ch
eck
Enables sending continuity check messages.
Step 8
interface gigabitethernet slot/port
Example:
Router(config-ecfm-srv)#interface
gigabitethernet 0/2
Specifies an interface and enters the interface
configuration mode.
Step 9
ethernet cfm mep domain domain-name
mpid mpid-value service service-name
Example:
Router(config-if)#ethernet cfm mep
domain customer mpid 100 service
customer1101
Sets a port to a maintenance domain and defines it as an
MEP.
Note The values for domain and service must be the
same as the values that were configured for CFM.
Step 10
interface gigabitethernet
slot/port.subinterface
Example:
Router(config-if-ecfm-mep)#interface
gigabitethernet 0/2.1
Specifies a subinterface and enters the subinterface
configuration mode.
Step 11
encapsulation dot1q vlan-id
Example:
Router(config-subif)#encapsulation
dot1q 100
Defines the encapsulation format as IEEE 802.1Q
(dot1q), and specifies the VLAN identifier.
Step 12
end
Example:
Router(config-subif)#end
Returns the router to the privileged EXEC mode.
