You can specify the number of continuity check messages that can be lost before marking
the MEP as down. The default value is three (PDUs).
To configure the loss threshold, include the loss-threshold statement at the [edit protocols
oam ethernet connectivity-fault-management maintenance-domain domain-name
maintenance-association ma-name continuity-check] hierarchy level.
Continuity measurement is provided by an existing continuity check protocol. The
continuity for every remote MEP is measured as the percentage of time that remote MEP
was operationally up over the total administratively enabled time. Here, the operational
uptime is the total time during which the CCM adjacency is active for a particular remote
MEP and the administrative enabled time is the total time during which the local MEP is
active. You can also restart the continuity measurement by clearing the currently measured
operational uptime and the administrative enabled time.
