Default Configuration

User Guidelines

This feature 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/g5

.

console(config)#interface ethernet 1/g5

console(config-if-1/g5)#spanning-tree portfast

spanning-tree port-priority

priority. To reset the default port priority, use the no form of this command.
