5.5.2.2 Bridge Port Parameters Screen Fields
Port Priority:
Displays the part of the port identifier which is used with the Spanning
Tree Algorithm when determining which port in a LAN segment has
priority. This information can be edited to change topology if needed.

Port State:
Indicates whether the indicated port is disabled, listening, learning,
forwarding, or blocking.

A change to this parameter can be made to effect a needed change in path
cost and bridge topology.

the root bridge on the network.
