Spanning Tree Portfast (Cisco)

Design & Configure

Spanning Tree Portfast (Cisco)

Technology: Switching
Area: STP
Vendor: Cisco
Software: 12.X , 15.X
Platform: Catalyst platforms

Portfast feature causes a switch port to enter the spanning tree forwarding state immediately, bypassing the listening and learning states. Portfast on switch ports connected to a single workstation or server allows those devices to connect to the network immediately, instead of waiting for the port to transition from the listening and learning states to the forwarding state.

To configure spanning tree portfast feature enter below commands:

Switch# configure terminal
Switch(config)# interface FastEthernet 0/1
Switch(config-if)# spanning-tree portfast
Switch(config-if)# end
Switch(config)# show spanning-tree
