Configuring Ethernet Oam Interaction With Cfm; Configuring The Oam Manager - Cisco ME 3400 Software Configuration Manual

Chapter 41 Configuring Ethernet OAM, CFM, and E-LMI

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 inward facing 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

Beginning in privileged EXEC mode, follow these steps to configure the OAM manager on a PE device:
Command
Step 1 configure terminal
Step 2
ethernet cfm domain domain-name level level-id
Step 3 service csi-id vlan vlan-id
Step 4 exit
Step 5 ethernet evc evc-id
Step 6
oam protocol cfm svlan vlan-id domain
domain-name
Step 7 exit
Step 8
Repeat Steps 2 through 7 to define other CFM domains that you want OAM manager to monitor.
Step 9 ethernet cfm enable
Step 10 end
Step 11

Purpose
Enter global configuration mode.
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.
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.
Return to global configuration mode.
Define an EVC, and enter EVC configuration mode
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.
Return to global configuration mode.
Globally enable CFM.
Return to privileged EXEC mode.
(Optional) Save your entries in the configuration file.
