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.)
