Far-end failure detection
Far-End Failure Detection (FEFD) is a protocol that senses remote data link errors in a network.
FEFD uses a link layer echo protocol to detect and signal far-end failures over Ethernet and optical links. When you enable FEFD, switches
periodically exchange FEFD echo frames to identify link failures. If the local switch does not receive an echo from its peer for the time
interval of three times the congured FEFD message interval, the local switch assumes that the peer link is down. The default interval for
FEFD message interval is 15 seconds. For example, with the default conguration, if the local switch does not receive an echo message for
45 seconds from its peer, it brings the peer link down.
