Abstract:
Methods and systems are disclosed. The method comprises: designating a first plurality of links from a first stack segment to a second stack segment as a first etherchannel link; designating a second plurality of links from the first stack segment to a third stack segment as a second etherchannel link, where the second stack segment and the third stack segment are in communication with a fourth stack segment; designating the first etherchannel link and the second etherchannel link as members of a hierarchical etherchannel link; and sending a packet from the first stack segment to the fourth stack segment using the hierarchical etherchannel link.
