Figure 36. Port Spanning Tree Settings Page
The following fields are displayed:
 Interface— Port ID.
 Configured Path Cost— Cost of a port to the root bridge. This
cost is combined with the costs of the other ports in the path to the
root bridge to determine the total path cost. The lower the numeric
value, the higher the priority of the path. The range is 1 to
200,000,000.
 Priority— Port priority number for the switch. The device with the
lowest priority number in the spanning tree domain becomes the
root bridge. If two or more devices have the same priority value,
the device with the numerically lowest MAC address becomes the
root bridge.
