Command Usage
Bridge priority is used in selecting the root device, root port, and
designated port. The device with the highest priority becomes the STA
root device. However, if all devices have the same priority, the device
with the lowest MAC address will then become the root device.
Example
spanning-tree pathcost method
This command configures the path cost method used for Rapid Spanning
Tree. Use the

Command Usage
The path cost method is used to determine the best path between
devices. Therefore, lower values should be assigned to ports attached to
faster media, and higher values assigned to ports with slower media.
Note that path cost (page 4-190) takes precedence over port priority
(page 4-191).
