Spanning Tree Commands

This command only applies to access ports. The command is to be used only 

with interfaces connected to end stations. Otherwise, an accidental topology 

loop could cause a data packet loop and disrupt switch and network 

operations.
An interface with PortFast mode enabled is moved directly to the spanning 

tree forwarding state when linkup occurs without waiting the standard 

forward-time delay.

The following example enables PortFast on 1/0/5

.

console(config)#interface gigabitethernet 1/0/5

console(config-if-1/0/5)#spanning-tree portfast

The spanning-tree portfast bpdufilter default command discards BPDUs 

received on spanning-tree ports in portfast mode. Use the “no” form of the 

command to disable discarding.

This feature is disabled by default.

Global Configuration mode

There are no usage guidelines for this command.
