•
When cross-check is configured, and a session with an expected MEP times out, EFD is triggered on
the local MEP.
•
No CCMs are received from a peer MEP appearing in the configured cross-check list.
•
An RDI is being received from a peer MEP.
•
The MEP is receiving an AIS/LCK.
The MEP will bring the interface back up when the error condition is no longer detected.
When an interface is shut down by a MEP using EFD, the MEP will continue to send and receive CCMs
and other CFM messages.
