Configuration Examples for Configuring Ethernet CFM for the Cisco ISR G2 Routers
The following two examples show configurations for a network. Configurations are shown not only for
the Carrier Ethernet Cisco ISR G2 Routers, but also for the devices used at the access and core of the
service provider’s network.

Example: Provisioning a Network
This configuration example shows only CFM-related commands. All commands that are required to set
up the data path and configure the VLANs on the device are not shown. However, it should be noted that
CFM traffic will not flow into or out of the device if the VLANs are not properly configured.
CE-A Configuration
Step 3
ethernet cfm domain
domain-name
level
level-id
Example:
Router(config)# ethernet cfm domain
Customer level 7
Defines a CFM maintenance domain at a specified level
and enters Ethernet CFM configuration mode.
Step 4
mep mpid
mpid
Example:
Router(config-ecfm)# mep mpid 702
Statically defines the MEPs within a maintenance
association.
Step 5
exit
Example:
Router(config-ecfm)# exit
Returns the device to global configuration mode.
Step 6
ethernet cfm mep crosscheck
start-delay delay
Example:
Router(config)# ethernet cfm mep
crosscheck start-delay 60
Configures the maximum amount of time that the device
waits for remote MEPs to come up before the cross-check
operation is started.
Step 7
exit
Example:
Router(config)# exit
Returns the device to privileged EXEC mode.
Step 8
ethernet cfm mep crosscheck {enable |
disable} domain
domain-name
] {port |
vlan {
vlan-id
|
vlan-id - vlan-id
| ,
vlan-id - vlan-id
}}
Example:
Router# ethernet cfm mep crosscheck
enable domain cust4 vlan 100
Enables cross-checking between the list of configured
remote MEPs of a domain and MEPs learned through
CCMs.
