The following fields are displayed:
 Interface— Port number.
 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
200000000.
 Priority (0-15)— Bridge 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.
