Chapter 4 Configuring the Cisco MWR 2941 Router Using the CLI
Configuration Sequence
Router(config-if)# switchport trunk native vlan 600
d. If you want to set the port as internal to a maintenance domain and define it as a maintenance
endpoint (MEP) use the ethernet cfm mep domain mpid command in interface configuration
mode. This command enters Ethernet CFM MEP configuration mode.
Router(config-if)# ethernet cfm mep domain CISCO_5 mpid 529 vlan 1
e. If you want to provision a maintenance intermediate point (MIP) at a specified maintenance level
on the interface, use the ethernet cfm mip level command in interface configuration mode.
Router(config-if)# ethernet cfm mip level 5
f. Exit interface configuration mode.
Router(config-if)# exit
Step 13 Use the ethernet cfm cc enable level vlan command in global configuration mode to globally enable
transmission of continuity check messages (CCMs).
Router(config)# ethernet cfm cc enable level 0-7 vlan 1-4094
For more information about how to configure CFM, see the Cisco IOS Carrier Ethernet Configuration
Guide, Release 12.2SR.
Configuring and Enabling the Cross-Check Function
Follow these steps to configure and enable cross-checking for an inward facing MEP. This task requires
you to configure and enable cross-checking on two devices. This task is optional.
Step 1 Enter enable mode.
Router> enable
Step 2 Enter the password.
Password: password
When the prompt changes to Router, you have entered enable mode.
Step 3 Enter global configuration mode.
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Step 4 Use the ethernet cfm domain command to define an outward CFM domain at a specified level and enter
Ethernet CFM configuration mode.
Router(config)# ethernet cfm domain Customer level 7 direction outward
Step 5 Use the mep crosscheck mpid command to statically define a remote MEP on a VLAN within a
specified domain.
Router(config-ether-cfm)# mep crosscheck mpid 401 vlan 100
Step 6 Exit to global configuration mode.
Router(config-ether-cfm)# exit
Router(config)#
Step 7 Use the ethernet cfm mep crosscheck start-delay command to configure the maximum amount of time
that the router waits for remote MEPs to come up before starting the cross-check operation.
