Command Usage
• This command is used to enable/disable the fast spanning-tree mode for
the selected port. In this mode, ports skip the Discarding 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 a LAN segment that is at
the end of a bridged LAN or for an end-node device.)
