Configuration Using Web Based Management and the Command Line Interface
● PathCost
This parameter is used to specify the preferred data paths between the root
bridge and other bridges and the value should be based on the transmission
speed. The faster a connection, the lower the value for PathCost should be.
You can specify values between 0 and 65535. The default is 100. The spanning
tree algorithm selects the transmission path for which the sum of all individual
values is the lowest.
