Port Priority

The priority for the port within the CST. This value is used in determining which port on a 

switch becomes the root port when two ports have the same least-cost path to the root. The 

port with the lower priority value becomes the root port. If the priority values are the same, the 

port with the lower interface index becomes the root port.

Port Path Cost

The path cost from the port to the root bridge.
