•
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.
