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.
