OS 12.3 Ethernet Interfaces Configuration Guide
Configuring a Remote Maintenance Endpoint Action Profile
You can specify the name of the action profile to use for the remote MEP.
To configure the action profile, include the action-profile profile-name statement at the
[edit protocols oam ethernet connectivity-fault-management maintenance-domain
domain-name maintenance-association ma-name mep mep-id remote-mep mep-id]
hierarchy level. The profile must already be defined at the [edit protocols oam ethernet
connectivity-fault-management] hierarchy level.
Configuring Maintenance Endpoint Service Protection
You can enable service protection for a VPWS (Virtual Private Wire Service) over MPLS
by specifying a working path or protect path on the MEP. Service protection provides
end-to-end connection protection of the working path in the event of a failure.
To configure service protection, you must create two separate transport paths a working
path and a protect path. You can specify the working path and protect path by creating
two maintenance associations. To associate the maintenance association with a path,
you must configure the MEP interface statement within the maintenance association
and specify the path as working or protect.
To configure the MEP interface, include the interface statement at the [edit protocols
oam ethernet connectivity-fault-management maintenance-domain domain-name
maintenance-association ma-name mep mep-id hierarchy level. On the interface statement,
specify the path as (working | protect). The direction must also be configured as direction
down for both sessions.

NOTE: If the path is not specified, the session monitors the active path.
Table 16 on page 194 describes the available service protection options.
Description
Specifies the working path.
Specifies the protect path.
The following configuration example shows service protection is enabled for the VPWS
service. The CCM session is configured for the working path and references the CCM
session configured for the protect path in the protect-maintenance-association statement.
The APS profile is configured and associated with the maintenance-association for the
working path:
