Far-End Failure Detection

FEFD is a protocol that senses remote data link errors in a network. FEFD responds by sending a
unidirectional report that triggers an echoed response after a specified time interval. You can enable FEFD
globally or locally on an interface basis. Disabling the global FEFD configuration does not disable the
interface configuration.
