Spanning tree protocol enabled n-node link aggregation system

An Information Handling System (IHS), comprising:

• a plurality of Inter-Chassis Links (ICLs) that couple a plurality of ICL ports to a first of a plurality of link aggregation node devices that has been designated as a root bridge by via the spanning tree protocol running on each of the plurality of link aggregation node devices;
• a Link Aggregation Group (LAG) that includes a plurality of LAG ports and that is coupled to a networking device;
• a processing system that is coupled to the plurality of ICL ports and the plurality of LAG ports, and
• a memory system that is coupled to the processing system and that includes instructions that, when executed by the processing system, cause the processing system to provide an enhanced spanning tree protocol engine that is configured to:
• determine that a first ICL port of the plurality of ICL ports has been designated as a first root port via the spanning tree protocol;
• determine that a second ICL port of the plurality of ICL ports has been designated as an alternate port via the spanning tree protocol;
• and
• redesignate, in response to the first ICL port being designated as the first root port and the second ICL port being designated as the alternate port, the second port as a second root port.

A method for enabling the spanning tree protocol in an n-node link aggregation system. comprising:

• coupling, by a link aggregation engine, a plurality of ICL ports to a first of a plurality of link aggregation node devices via a plurality of Inter-Chassis Links (ICL);
• aggregating, by the link aggregation engine, at least one Link Aggregation Group (LAG) port to provide a LAG;
• designating, via the spanning tree protocol running on each of a plurality of link aggregation node devices, the first of the plurality of link aggregation node devices as a root bridge;
• determining, by an enhanced spanning tree protocol engine, that a first ICL port of the plurality of ICL ports has been designated as a first root port via the spanning tree protocol;
• determining, by the enhanced spanning tree protocol engine, that a second ICL port of the plurality of ICL ports has been designated as an alternate port via the spanning tree protocol;
• and
• redesignating, by the enhanced spanning tree protocol engine in response to the first ICL port being designated as the first root port and the second ICL port being designated as the alternate port, the second port as a second root port.
