Abstract:
A network device having a distributed, multi-stage forwarding architecture uses a two-stage process for planned orderly offlining of switch fabric components. The process includes a prepare stage in which preparations are made from downstream components to upstream components for offlining and new spray weights are calculated but not applied, and a commit stage in which new spray weights are committed and applied to traffic from upstream components to downstream components.
