By default, the system automatically detects the speed and duplex mode used on each port, and configures the
path cost according to the values shown below. Path cost "0" is used to indicate auto-configuration mode. When
the short path cost method is selected and the default path cost recommended by the IEEE 8021w standard
exceeds 65,535, the default is set to 65,535.
