The path cost for the specified STP port object in the associated STP instance.
An interface path cost represents the relative cost of sending network
traffic through that interface. In calculating the spanning tree,
the algorithm tries to minimize the total path cost between each point
and the root bridge. By manipulating the path costs of different
interfaces, it's possible to steer traffic toward paths that are faster,
more reliable, and/or more economical. Path costs have a range of
1-200,000,000, and the default path cost for an interface is based on
the interface's maximum speed (not the actual speed).
Max interface speed Default path cost
10 Gb/s 2,000
1 Gb/s 20,000
100 Mb/s 200,000
10 MB/s 2,000,000
The default path cost is a function of the interface's maximum speed,
not its actual speed, so the default path cost of a 10/100/1000 Mb/s
interface will be 20,000 even if the interface is running at 10 Mb/s.
Changes in link speed don't cause path costs to change.
Link aggregation doesn't affect the default path cost,
i.e. a trunk of four 1 Gb/s interfaces will still have a default path
cost of 20,000.
In STP or RSTP mode, only STP instance 0 is valid.
