Path cost takes precedence over port priority.

When the path cost method ( page 1077 ) is set to short, the maximum
value for path cost is 65,535.

You can enable this option if an interface is attached to a LAN segment that
is at the end of a bridged LAN or to an end node. Since end nodes cannot
cause forwarding loops, they can pass directly through to the spanning tree
forwarding state. Specifying Edge Ports provides quicker convergence for
devices such as workstations or servers, retains the current forwarding
database to reduce the amount of frame flooding required to rebuild
address tables during reconfiguration events, does not cause the spanning
tree to initiate reconfiguration when the interface changes state, and also
overcomes other STA-related time out problems. However, remember that
Edge Port should only be enabled for ports connected to an end-node
device.
