SPANNING TREE COMMANDS

Command Mode

Interface Configuration (Ethernet, Port Channel)

Command Usage

•This command is used to enable/disable the fast spanning-tree mode for the selected port. In this mode, ports skip the Blocked, Listening and Learning states and proceed straight to Forwarding.

•Since end-nodes cannot cause forwarding loops, they can be passed through the spanning tree state changes more quickly than allowed by standard convergence time. Fast forwarding can achieve quicker convergence for end-node workstations and servers, and also overcome other STA related timeout problems. (Remember that fast forwarding should only be enabled for ports connected to an end-node device.)

Example

Console(config)#interface ethernet 1/5

Console(config-if)#spanning-tree portfast

Console(config-if)#

show spanning-tree

Use this command to show the spanning tree configuration.
