Priority Priority is used in determining the root device, root port and designated port. The device
with the highest priority (lowest numeric value) becomes the STP root device. If all
devices have the same priority, the device with the lowest MAC address will then
become the root device. The allowed range is 0 to 255. The lower the numeric value you
assign, the higher the priority for this device.
Path Cost Path cost is the cost of transmitting a frame on to a LAN through that port. It is assigned
according to the speed of the link. The slower the media, the higher the cost (refer to the
table on path cost in the section on STP).
