Abstract
A packet switch contains a link state group manager that forms supergroups from multiple link aggregations. The link state group manager collects state information for the link aggregations in a supergroup, and uses state criteria to determine whether the link aggregations are allowed to be up, as a supergroup, for data traffic. This allows a supergroup of links to only come up when it meets a minimum performance criteria, with traffic routed around the supergroup when the supergroup cannot meet the minimum performance criteria, even if some link aggregations in the group are functional.
