Chapter 57 Configuring Ethernet OAM and CFM
Ethernet CFM and Ethernet OAM Interaction
Configuring the OAM Manager
To configure the OAM manager on a PE device, perform this task:
Enabling Ethernet OAM
To enable Ethernet OAM on an interface, perform this task:
Command Purpose
Step 1
Switch# configure terminal
Enters global configuration mode.
Step 2
Switch(config# interface interface-id
Defines an interface to configure as an Ethernet OAM
interface and enter interface configuration mode.
Step 3
Switch(config-if)# ethernet cfm domain
domain-name level level-id
Defines 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 4
Switch(config-if)# service csi-id vlan vlan-id
Defines 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 5
Switch(config-if)# exit
Returns to global configuration mode.
Step 6
Switch(config)# ethernet evc evc-id
Defines an EVC, and enter EVC configuration mode
Step 7
Switch(config-evc)# oam protocol cfm svlan
vlan-id domain domain-name
Configures 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.
Step 8
Switch(config-evc)# exit
Returns to global configuration mode.
Step 9
Repeat Steps 2 through 7 to define other CFM domains that you want OAM manager to monitor.
Step 10
Switch(config)# ethernet cfm enable
Globally enables CFM.
Step 11
Switch(config)# end
Returns to privileged EXEC mode.
Step 12
Switch# copy running-config startup-config
(Optional) Saves your entries in the configuration file.
Command Purpose
Step 1
Switch# configure terminal
Enters global configuration mode.
Step 2
Switch(config# interface interface-id
Defines an interface to configure as an Ethernet OAM
interface and enter interface configuration mode.
