Command Line Interface

Command Usage
• This command defines the priority for the use of a port in the Spanning Tree
Protocol. If the path cost for all ports on a wireless bridge are the same, the
port with the highest priority (that is, lowest value) will be configured as an
active link in the spanning tree.
• Where more than one port is assigned the highest priority, the port with lowest
numeric identifier will be enabled.
Example

Use this command to set an interface to fast forwarding. Use the no form to disable
fast forwarding.

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 devices, and also overcome other STP 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.)
