Spanning tree protocol (stp) implementation on an event driven virtual link aggregation (vlag) system

A method for providing, virtual link aggregation (vLAG), the method comprising:

• forming a first logical port using one or more of a first plurality of physical networking ports comprised in a first networking system;
• forming a second logical port using one or more of a second plurality of physical networking ports comprised in a second networking system;
• forming a third logical port using the first logical port and the second logical port;
• determining first networking protocol state information corresponding to the third logical port using the first networking, system, wherein the first networking protocol state information includes an indication of whether the first networking system is capable of communicating with the second networking system via an interswitch link (ISL);
• storing a first networking protocol state information corresponding to the third logical using the first networking system;
• communicating, the first networking protocol state information to the second networking system via the ISL;
• and
• storing the first networking protocol state information using the second networking system.
