STP PortFast


To configure [STP PortFast](/stp-portfast) on a Cisco device running [STP](/stp), there are two approaches:

The `spanning-tree portfast edge` command can be applied either globally or on an interface.  
When applied globally, the syntax is as follows:

`spanning-tree portfast edge { bpdufilter default | bpduguard default | default }`

When applied on an interface, the syntax is like so:

`spanning-tree portfast edge [ disable | trunk ]`

The interface configuration always overrides the global configuration. If no such command appears in the interface configuration, then the global configuration takes effect.
