Chapter 4 Configuring the Cisco MWR 2941 Router Using the CLI
Configuration Sequence
Configuring Ethernet CFM
The following sections describe how to configure Ethernet CFM.
• Configuring Global settings
• Configuring and Enabling the Cross-Check Function
• Configuring Ethernet Link Operations, Administration, and Maintenance (OAM)
Note For additional information about Ethernet CFM, see the Cisco IOS Carrier Ethernet Configuration
Guide, Release 12.2SR.
Configuring Global settings
Step 1 Use the ethernet cfm enable command to enable Ethernet CFM.
Note Release 12.2(33)MRA supports the Draft 1.0 version of Ethernet CFM; it does not support the IEEE
802.1ag-2007 version.
Router(config)# ethernet cfm enable
Step 2 Follow these steps to configure an Ethernet CFM domain.
a. Use the ethernet cfm domain command to define a CFM maintenance domain at a particular
maintenance level and enter Ethernet CFM configuration mode.
Router(config)# ethernet cfm domain CUST_L6 level 6
Router(config-ether-cfm)#
b. Use the mep archive-hold-time command to set the amount of time, in minutes, that data from a
missing maintenance end point (MEP) is kept in the continuity check database or that entries are
held in the error database before they are purged.
Router(config-ether-cfm)# mep archive-hold-time 1000
c. Use the service command to configure a maintenance association within a maintenance domain and
enter connectivity fault management (CFM) service configuration mode. You can use the following
parameters:
– ma-name—The maintenance association ID (MAID) is a combination of a maintenance domain
ID and the short maintenance association name.
– ma-num—Integer from 0 to 65535 that identifies the maintenance association.
– vlan-id—Configures a primary VLAN.
– vpn-id—Configures a virtual private network (VPN).
Router(config-ether-cfm)# service CE_600 vlan 600
Repeat this step to define multiple services within a single domain.
d. Exit CFM service configuration mode.
Router(config-ether-cfm)# exit
Router(config)#
e. Repeat steps 1–3 to create additional CFM maintenance domains.
