A METHOD AND SYSTEM FOR SYNCHRONIZING WITH NEIGHBOR IN A DISTRIBUTED RESILIENT NETWORK INTERCONNECT (DRNI) LINK AGGREGATION GROUP

摘要

A method supporting a distributed resilient network interconnect (DRNI) in a link aggregation group upon communication failure at a network device is disclosed. The method starts with determining that the network device receives traffic from the partner network device. Then it is determined that the network device is coupled to the neighbor network device in the first portal of the link aggregation group; that an operation key received from the partner network device has been updated; and that the network device no longer communicates with the neighbor network device. The network device then halts transmitting and receiving frames of the link aggregation group at the network device upon determining that the first portal has a higher portal priority than the second portal, wherein each portal is assigned a portal priority.
