MAs).

config – Sends a trap if this device receives a CCM with the same
MPID as its own but with a different source MAC address, indicating
that a CFM configuration error exists.
loop – Sends a trap if this device receives a CCM with the same
source MAC address and MPID as its own, indicating that a
forwarding loop exists.
mep-down – Sends a trap if this device loses connectivity with a
remote MEP, or connectivity has been restored to a remote MEP
which has recovered from an error condition.
mep-up – Sends a trap if a remote MEP is discovered and added to
the local database, the port state of a previously discovered remote
MEP changes, or a CCM is received from a remote MEP which as an
expired entry in the archived database.
