57-17 spanning-tree portfast
This command is used to enable fast forwarding mode where the interface is immediately put into the forwarding state
upon linkup without waiting for the timer to expire.

Specifies the external cost of interface. Valid values are from 0 to 200000000 and 0
means auto.
The default port cost is calculated by port speed.
Interface Configuration Mode.
Level: 8
This command is used to configure the path cost between MST regions from the
transmitting Bridge to the CIST Root Bridge.
This example shows how to configure the external path cost.
Specifies to disable the portfast on the interface.
The default vaule is disabled.
Interface Configuration Mode.
Level: 8
You should use this command only with interfaces that connect to end stations;
otherwise, an accidental topology loop could cause a data-packet loop and disrupt
the switch and network operation.
An interface with portfast mode enabled is moved directly to the spanning-tree
forwarding state when linkup occurs without waiting for the standard forward-time
delay.
This example shows how to configure the portfast state.
