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.

HI SHAHIN
1. WHEN YOU ARE ENABLING SPANNING TREE PORTFAST ON ANY
INTERFACE THAT MEAN YOU ARE KILL SPANNING TREE ON THE PORT.
PORT NEVER TAKE PARTICIPATES ON THE ELACTION OF ROOT BRIDGE.
2. AND PORTFAST FEATURE BYPASS THE LISTENING, LEARNING
AND MAX AGE
3. YOU CAN ENABLE BPDU GUARD FEATURE ON ALL NON-TRUNKING
FOR TO PROTECT YOUR TOPOLOGY TO RECEIVING ANY BPDU
4. ROOT GUARD FEATURE ENABLE ONLY BETWEEN ROOT AND NON
ROOT BRIDGE SWITCH AND NEVER USE IT BETWEEN PRIMARY AND
SECONDRY ROOT BRIDGE.
