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.
