Abstract:
1. A method of propagating port state to a network device having a static link aggregation to two or more intermediary devices of a cluster, the method comprising: (a) establishing, by the two or more intermediary devices of a cluster comprising a plurality of intermediary devices intermediary to a plurality of clients and a plurality of servers, a static link aggregation with a network device in communication with the cluster, the static link aggregation comprising aggregated ports from different intermediary devices; (b) detecting, by a first intermediary device of the static link aggregation, that a health of the first intermediary device is below a predetermined threshold; (c) identifying, by the first intermediary device responsive to the detection, one or more ports in the aggregated ports of the static link aggregation; and (d) disabling, by the first intermediary device of the static link aggregation responsive to the identification, the one or more ports to notify the network device that the first intermediary device is unavailable; (e) detecting, by the first intermediary device, that the health of the first intermediary device is above the predetermined threshold; and (f) adding, by the first intermediary device responsive to the detection that the health is above the predetermined threshold, one or more ports to the static link aggregation with the network device in communication with the cluster.
