Specifying the Root Port and Designated Port
The root port and designated port are always the ports with the lowest path costs. If the
costs are the same, the priority is the decisive criterion. If the priorities are also the same,
the port number is the decisive criterion. Specify an appropriate combination of costs and
priority on the "STP Port Configuration" page in WBM for the port specified as the root port
or designated port. Make sure that all the other network switches either have higher costs
or a lower priority (higher value).
