Abstract:
A system and method for enabling a disabled port on a device such as a Two Port Medium Access Control (MAC) Relay (TPMR), which relays MAC frames in a communication network. When a link in the network fails, the TPMR disables the port due to operation of a link failure propagation protocol. When the TPMR detects that the failed link is repaired, the TPMR stops transmitting link failure Packet Data Units (PDUs) and transmits a Link Failure Terminating PDU to other connected TPMRs in the network. Receipt of the Link Failure Terminating PDU indicates the failed link is repaired and all ports disabled as a result of the failure should consequently be enabled.
