Briefly describe the spanning tree portfast STP feature.
What will be an ideal response?
STP has some additional features. For example, the spanning tree portfast feature allows you to configure a switch to bypass some of the latency (delay) associated with the switch ports transitioning through all of the STP transitory states before they reach the forwarding state. You should only use this command if you are certain that the devices connected to your switch will not cause a bridge loop. Suppose, for example, that you have a 2950 switch with 24 ports; that 22 of those ports are used to connect PCs, servers, and printers; and that the last two ports are used for uplinks. You can configure ports 1 to 22 with the portfast option. When the switch is recycled, the ports will come up in forwarding mode, reducing the downtime of your other components.
