Methods and apparatus for efficient use of link aggregation groups

Abstract:

An apparatus includes a first edge device configured to receive a data unit destined to a peripheral processing device that is operatively coupled to a network interconnect via a LAG associated with a second edge device and a third edge device. The first edge device is configured to select an edge device set that includes the third edge device and excludes the second edge device, from a group of edge device sets. Each edge device set from the group of edge device sets is directly coupled to the peripheral processing device. The first edge device is configured to send an instance of the data unit to each edge device from the edge device set such that the third edge device sends an instance of the data unit to the peripheral processing device based on a selection method that omits ports on the second edge device as potential selections.
