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.)
