Abstract
A high-availability network device cluster role synchronization technique for devices configured with multiple network controllers is disclosed. An HA node may contain information regarding a role within a cluster for that HA node. This information should properly be maintained or erased based on a type of failover for an HA device. For example, if there is a loss of the active controller that causes only a controller failover, changes to the role of the HA node may not be necessary. Thus, an election process within a cluster may be avoided. However, if a failover of an entire HA node occurs (or restart of an HA node), role information prior to the restart may not be applicable and an election process may need to be initiated such that the cluster may continue to function. Different types of roles may exist for nodes within a cluster.
