Abstract
An apparatus includes a local compute node connected to a first networking switch by a direct local link. The first switch reduces its priority in response to determining that that the first networking switch is currently unable to establish the bi-directional communication with the local compute node through the direct local link. If the reduced priority of the first networking switch is greater than a priority of each of at least one additional networking switch in a cluster, then the first networking switch operates as a master networking switch for the cluster. If the reduced priority of the first networking switch is less than the priority of any of the at least one networking switch, then the first networking switch operates as a standby networking switch and one of the atleast one additional networking switch having the highest priority is operated as the master networking switch for the cluster.
