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 configured 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 configuration, if the local switch does not receive an echo message for 45 seconds from its peer, it brings the peer link down. Layer 2 265
