What happens when a PortFast port receives a Bpdu?

PortFast causes a switch or trunk port to enter the spanning tree forwarding state immediately, bypassing the listening and learning states. Once a portfast port receives a BPDU , it is supposed to lose portfast status and go back through the listening/learning phases at which point it is not forwarding traffic.Click to see full answer. Considering this, what happens if a PortFast port receives a Bpdu?Answer: If a Portfast enabled port receives BPDUs it will lose its Portfast status, regardless if configured on interface or globally. If it has the command on it and you shut/no shut then I assume that any state is lost and it would do what the config says which is to bring the port into forwarding immediately.Secondly, does PortFast port send Bpdu? Not only does a PortFast-enabled port transmit BPDUs, but the operational PortFast status is actually dependent on incoming BPDUs. If the port receives BPDUs, the PortFast feature is disabled. Also to know is, what would happen if you typed Spanning Tree PortFast trunk and the port receives Bpdu? When you receive a BPDU on a portfast enabled interface then it will lose its portfast status, disables BPDU filtering and acts as a normal interface. Interface: if you enable BPDUfilter on the interface it will ignore incoming BPDUs and it will not send any BPDUs. This is the equivalent of disabling spanning-tree.What will take place on the port that enabled PortFast?Enabling the PortFast feature causes a switch or a trunk port to enter the STP forwarding-state immediately or upon a linkup event, thus bypassing the listening and learning states. The PortFast feature is enabled at a port level, and this port can either be a physical or a logical port.
