Configuring the Continuity Check Interval

You can specify the continuity check message (CCM) interval. The interval is the time between the transmission of CCMs. You can specify 10 minutes (10m), 1 minute (1m), 10 seconds (10s), 1 second (1s), 100 milliseconds (100ms), or 10 milliseconds (10ms). The default value is 1 minute.

Note: For the continuity check message interval to be configured for 10 milliseconds, periodic packet management (PPM) runs on the Routing Engine and Packet Forwarding Engine (PFE) by default. You can only disable PPM on the PFE. To disable PPM on the PFE, use the no-delegate-processing statement at the [edit routing-options ppm] hierarchy level.

To configure the interval, include the interval statement at the [edit protocols oam ethernet connectivity-fault-management maintenance-domain domain-name maintenance-association ma-name continuity-check] hierarchy level.
