Abstract
Stackable Layer 2 switches may be upgraded through a stateless upgrade procedure that minimizes software upgrade complexity while leveraging the intrinsic redundancy of the network to minimize traffic disruption. Disclosed methods may be targeted to platforms that lack support for other non-disruptive upgrade technologies, but that can leverage the intrinsic network redundancy to minimize traffic impact during a stack upgrade.
