Path Cost:
Text Field. Enter the path cost. The path cost
represents the performance cost of sending information through
a port and measures the impact of sending packets through the
network. The path cost setting establishes a hierarchy among the
ports of the spanning tree topology. A high cost indicates a low
position in the topology. A low cost indicates a high position in
the topology. By setting a high path cost to a port, you discourage
high-volume traffic and eliminate slow data links.
The port path cost is based on the root path cost, when the port
is the root port of the bridge. The path cost must be a number
between 0 and 65535.

Priority:
Text Field. Enter the priority of the port. When you
change this field you change the first two digits of the priority
number. The priority determines the port to use when two ports
have the same calculated path cost. The port with the lowest ID
number is the one that is used.
