Spanning-Tree Portfast Bpdufilter Default - Dell PowerEdge M420 Reference Manual

Default Configuration
PortFast mode is disabled.
Command Mode
Interface Configuration (gigabitethernet, port-channel, tengigabitethernet)
mode
User Guidelines
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.
Example
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
