DESCRIPTION

Priority

 

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.

 

 

Enter a value from 0~61440.

 

 

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

 

 

bridge.

 

 

Priority determines the root bridge, which in turn determines the Root

 

 

Hello Time, Root Maximum Age and Root Forwarding Delay.

 

 

 

Pathcost

 

Path cost is the cost of transmitting a frame on to a LAN through that

 

 

port. It is recommended to assign this value according to the speed of

 

 

the bridge. The slower the media, the higher the cost.

Priority

Root refers to the base of the spanning tree (the root bridge). This

 

field displays the root bridge’s priority. This Switch may also be the root

 

bridge.

 

 

Max Age

This is the maximum time (in seconds) the Switch can wait without

 

receiving a configuration message before attempting to reconfigure.
