Method and system for rehabilitating disabled ports in a network with two retransmissions mac two ports.

摘要

Method in a network, to enable a port disabled in a device (104) adapted to retransmit frames of media access control (MAC) when the port is disabled due to operation of a protocol 5 of propagation link failure, comprising the method comprising the steps of: configuring a notification mechanism using link failure state parameters Internal Sublayer Service (ISS); detecting a failure (604) link or port at a first port of the device; notifying a second port device (608) of the first port failure; 10 periodically transmit PDUs (610) link failure through the second port of the device to a peer entity downstream answer PDUs Link Failure (LFPDUs) periodic received by a PDU Acknowledgment (ACK PDU) ; Start mechanism (614) fault reporting ISS Liaison if the 15 pair of downstream entity does not implement the protocol propagation of link failures; characterized by the steps of: in response to detecting that has been repaired link failure or port, stopping the periodic LFPDUs (620); and 20 transmit (620) Data Unit Protocol Completion of Link Failure (LFTPDU) (500) to signal that has been repaired link failure or port in order to rehabilitate the disabled port.
