CFM monitoring and show commands
6
If the linktrace and loopback to target-mep 2 fails, then the linktrace can be done on the MIPs on
PE1 and PE2 to know the exact failure.
Deployment scenario with PEs functioning as DOWN MEP
It is also possible to configure DOWN MEP on VLL end-points. For example, in Figure 10 , the DOWN
MEP can be configured to monitor the connectivity between CE1 and PE1 or to monitor the
connectivity between CE2 and PE2.
Configuring CE1
1. To enable CFM, enter the following command.
CE1(config)#cfm-enable
2. Create a maintenance domain with a specified name CUST_2 and level 6.
CE1(config-cfm)#domain-name CUST_2 level 6
3. Create a maintenance association within a specified domain of vlan-id 30 with a priority 3.
CE1(config-cfm-md-CUST_2)#ma-name ma_6 vlan-id 30 priority 3
4. Set the time interval between successive Continuity Check Messages.The default is
10-seconds.
CE1(config-cfm-md-CUST_2-ma-ma_6)#ccm-interval 10-second
5. Configure a MEP on port 1/1 and vlan 30.
CE1 (config-cfm-md-CUST_2-ma-ma_6)#mep 3 down vlan 30 port ethe 1/1
6. Configure a remote-mep.
CE1(config-cfm-md-CUST_1-ma-ma_5)#remote-mep 4 to 4
Configuring PE1
The MPLS-VLL configuration is the same as shown in the previous deployment scenario. If the VLL
configuration is not done prior to configuring maintenance association, the MA configuration will
not be allowed. Also the port and vlan in the MEP configuration should exist in the VLL
configuration prior to MEP configuration, otherwise it is not allowed. The port in the MEP
configuration can be either a tagged or untagged port already present in the VLL configuration.
1. To enable CFM, enter the following command.
PE1(config)#cfm-enable
2. Create a maintenance domain with a specified name CUST_2 and level 6.
PE1(config-cfm)#domain-name CUST_2 level 6
3. Create a maintenance association within a specified domain of vll-id 30 with a priority 3.
PE1(config-cfm-md-CUST_2)#ma-name ma_6 vll-id 30 priority 3
4. Set the time interval between successive Continuity Check Messages.The default is
10-seconds.
PE1(config-cfm-md-CUST_2-ma-ma_6)#ccm-interval 10-second
5. Configure a MEP on port 1/1 and vlan 30
CE-1 (config-cfm-md-CUST_2-ma-ma_6)#mep 4 down vlan 30 port ethe 1/1
