    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
