menu and drag down to Spanning Tree.
The scroll list at the top of the window lists each bridge port available on the
device and its current port priority. Below the Port List, the window includes the
following:
Priority (Port)
If two or more ports on the same bridge are connected to the same network
segment, each port will receive the same device-level values for Root ID, Root
Cost, and Bridge ID in ConÞguration BPDUs. In this case, the BPDUÕs port-level
informationÑthe transmitting portÕs identiÞer and its manageable Priority
componentÑ is used to determine which port on this bridge will be the
Designated Port for that segment. A lower number indicates a higher priority; the
default is 80. The allowable range is 0 to FF.
Path Cost
The portion of the total path cost associated with this port. Lowering a portÕs Path
Cost makes a port more competitive in the selection of the Designated Port. The
default value is 100 for Cabletron bridges. The allowable range is from 1 to 65535.
