Use this screen to check the current status of the STP feature. Click Advanced 
Settings > STP > STP Status to display the screen as shown.

Figure 53   STP Status 

The following table describes the labels in this screen. 

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.

Current Root Status
MAC Address

This is the MAC address of the root bridge.

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.
