Creating a Maintenance Association

In a CFM maintenance domain, each service instance is called a maintenance association.
To create a maintenance association:
[edit protocols oam ethernet connectivity-fault-management maintenance-domain

user@switch# set maintenance-association ma-name
Configuring the Continuity Check Protocol
The continuity check protocol is used for fault detection by a maintenance association
end point (MEP) within a maintenance association. The MEP periodically sends continuity
check multicast messages. The receiving MEPs use the continuity check messages (CCMs)
to build a MEP database of all MEPs in the maintenance association.
To configure the continuity check protocol:
Enable the continuity check protocol:
1.
[edit protocols oam ethernet connectivity-fault-management
maintenance-domain domain-name maintenance-association ma-name]
user@switch# set continuity-check
Specify the continuity check hold interval. The hold interval is the number of minutes
2.
to wait before flushing the MEP database if no updates occur. The default value is 10
minutes.

user@switch# set hold-interval number
Specify the CCM interval. The interval is the time between the transmission of CCMs.
3.
You can specify 10 minutes (10m), 1 minute (1m), 10 seconds (10s), 1 second (1s), 100
milliseconds (100ms), or 10 milliseconds (10ms).
