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 Method
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.
