Ethernet CFM and Ethernet OAM Interaction
For more information about CFM and interaction with Ethernet OAM, see the Carrier Ethernet
Configuration Guide, Cisco IOS Release 15M&T.
Configuring Ethernet OAM Interaction with CFM
For Ethernet OAM to function with CFM, you must configure an Ethernet Virtual Circuit (EVC) and the
OAM manager, and associate the EVC with CFM. You must use an up MEP for interaction with the OAM
manager.
Note If you configure, change, or remove a UNI service type, EVC, Ethernet service instance, or CE-VLAN
configuration, all configurations are verified to ensure that the UNI service types match the EVC
configuration and that Ethernet service instances are matched with the CE-VLAN configuration.
Configurations are rejected if the pairs do not match.
Configuring the OAM Manager
Follow this procedure to configure the OAM manager on a PE device.
BEFORE YOU BEGIN
Review the “Information About E-LMI” section on page 17-51 and “E-LMI and OAM Manager
Configuration Guidelines” section on page 17-52.
DETAILED STEPS
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
ethernet cfm domain domain-name level
level-id
Define a CFM domain, set the domain level, and
enter ethernet-cfm configuration mode for the
domain. The maintenance level number range is 0 to
7.
Step 3
service csi-id vlan vlan-id Define a universally unique customer service
instance (CSI) and VLAN ID within the
maintenance domain.
• csi-id—String of no more than 100 characters
that identifies the CSI.
• vlan-id—VLAN range is from 1 to 4095. You
cannot use the same VLAN ID for more than one
domain at the same level.
Step 4
exit Return to global configuration mode.
Step 5
ethernet evc evc-id Define an EVC, and enter EVC configuration mode
Step 6
oam protocol cfm svlan vlan-id domain
domain-name
Configure the EVC OAM protocol as CFM, and
identify the service provider VLAN-ID
(S-VLAN-ID) for the CFM domain maintenance
level as configured in Steps 2 and 3.
