DETAILED STEPS
Command Purpose
Step 1
enable
Example:
Router>enable
Enables the privileged EXEC mode.
Enter your password when prompted.
Step 2
configure terminal
Example:
Router#configure terminal
Enters the global configuration mode.
Step 3
ethernet cfm ieee
Example:
Router(config)#ethernet cfm ieee
Enables the IEEE version of CFM.
Step 4
ethernet cfm global
Example:
Router(config)#ethernet cfm global
Enables CFM processing globally on the router.
Step 5
ethernet cfm domain domain-name level
0 to 7
Example:
Router(config-ecfm)#ethernet cfm
domain customer level 7
Defines a CFM maintenance domain at a specified level,
and enters Ethernet CFM configuration mode.
level can be any value from 0 to 7.
Step 6
service service-name vlan vlan-id
inner-vlan inner vlan-id direction
down
Example:
Router(config-ecfm)#service
customer1101 vlan 100 inner-vlan 30
direction down
Enters the CFM service configuration mode.
The following are the parameters:
• vlan—Specifies the VLAN.
• inner-vlan—The inner-vlan keyword and the inner
vlan-id argument specify the VLAN tag for
double-tagged packets.
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.
