CFM monitoring and show commands
6
To monitor the connectivity between CE-1 and PE-1, you can use the show cfm connectivity
commands as mentioned in the previous scenario. You can also use the loopback or linktrace
commands on CE-1 or PE-1.
Deployment scenario with PEs functioning as UP MEP
UP MEPs can also be configured on PEs. This monitors connectivity of VLL end points.
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 would
not be allowed. Also the port and vlan in the MEP configuration should exist in VLL configuration
prior to MEP configuration, otherwise it will not be allowed. The port in the MEP configuration can
be either a tagged or untagged port already present in VLL configuration.
1. To enable CFM, enter the following command.
PE1(config)#cfm-enable
2. Create a maintenance domain with a specified name PROVIDER_1 and level 4.
PE1(config-cfm)#domain-name PROVIDER_1 level 4
3. Create a maintenance association within a specified domain of vll-id 30 with a priority 3.
PE1(config-cfm-md-PROVIDER_1)#ma-name ma_8 vll-id 30 priority 3
4. Set the time interval between successive Continuity Check Messages. The default is
10-seconds.
PE1(config-cfm-md-PROVIDER_1-ma-ma_8)#ccm-interval 10-second
CE1 (config-cfm-md-PROVIDER_1-ma-ma_8)#mep 6 up vlan 30 port ethe 1/1
Configuring PE2
The configuration on PE1 is similar to the PE1 configuration.
1. To enable CFM, enter the following command.
PE2(config)#cfm-enable
2. Create a maintenance domain with a specified name PROVIDER_1 and level 4.
PE2(config-cfm)#domain-name PROVIDER_1 level 4
3. Create a maintenance association within a specified domain of vll-id 30 with a priority 3.
PE1(config-cfm-md-PROVIDER_1)#ma-name ma_8 vll-id 30 priority 3
4. Set the time interval between successive Continuity Check Messages.The default is
10-seconds.
PE1(config-cfm-md-PROVIDER_1-ma-ma_8)#ccm-interval 10-second
CE1 (config-cfm-md-PROVIDER_1-ma-ma_8)#mep 7 up vlan 30 port ethe 2/1
To monitor the connectivity between PE1 and PE2, you could use the “show cfm
connectivity”
commands as mentioned in the previous scenario. Also you could use either
loopback or linktrace on PE1 or PE2.
