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.
