The present invention features embodiments of alleviating the impact to a system of stack switches, as well as to neighboring nodes communicating with such a system, when a primary master switch to secondary master switch failover occurs. The features of the present invention, generally enables a system of stack switches to retain, for a fixed or indefinite period of time, its stack address even when multiple primary master to secondary master failovers occur. This way recalculation of certain protocols-e.g., spanning trees and link aggregations-and updating of certain tables-e.g., address resolution protocol (ARP) and routing tables-are minimized.
