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??? As we knw that PortFast bypass the Listening & Learning State? How it will respond when a BPDU (Inferior or Superior) is received on that Port. Thanks in advance. Waiting for Replay.
