A device may detect and report failure in point-to-point Ethernet links. In one implementation, the device may determine, based on a periodic timing signal, whether at least one packet was received on an incoming Ethernet link during a previous period of the periodic timing signal. The device may update an entry in a circular buffer to indicate whether the at least one packet was received during the previous period of the periodic timing signal and analyze the circular buffer to determine whether there is a signal failure on the incoming Ethernet link.
