Hi Guys.. I hv a confusion in my mind. Plz help me to clear my concept. How a port respond when a PortFast port receives any BPDU. Please make sure that BPDU Guard, ROOT Guard are not considered in this scenario. Just a spanning tree without any enhancement. Will the port goes through STP port state???
