LABEL DESCRIPTION

Bridge Priority Bridge priority is used in determining the root switch, root port and designated port. The

switch with the highest priority (lowest numeric value) becomes the STP root switch. If all

switches have the same priority, the switch with the lowest MAC address will then become

the root switch. Select a value from the drop-down list box.

The lower the numeric value you assign, the higher the priority for this bridge.

Bridge Priority determines the root bridge, which in turn determines Hello Time, Max Age

and Forwarding Delay.

Hello Time This is the time interval in seconds between BPDU (Bridge Protocol Data Units)

configuration message generations by the root switch. The allowed range is 1 to 10

seconds.
