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 con-
vergence time. Fast forwarding can achieve quicker convergence for end-node
workstations and servers, and also overcome other STA related timeout prob-
lems. (Remember that fast forwarding should only be enabled for ports con-
nected to an end-node device.)
