Fault processing method based on intelligent resilient framework (IRF) system and equipment thereof

The invention discloses a fault processing method based on an intelligent resilient framework (IRF) system and equipment thereof. The method comprises the steps that: when the equipment in the IRF system detects multi-active conflicts and determines that the equipment self is in a recovery state, a port of a multiple access device (MAD) detection link of the equipment self is kept up, in addition, the port is set into a block state, and the MAD detection messages are exchanged with operation state equipment through the MAD detection link; when the MAD detection messages sent by the operation state equipment are not received in the preset time, protocol messages are sent to the operation state equipment through other ports of the MAD detection link port, and response messages returned by the opposite end are waited; and when the response messages returned by the operation state equipment are not received in the preset time, the uplink service port is closed, and the downlink service port is opened. When the fault processing method and the equipment are adopted, the complete isolation between a user network and an external network caused by the current operation state equipment fault after the IRF cracking occurs can be avoided.
