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 and
Multiple Spanning Tree. Use the no form to restore the default.
Syntax

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 4-164) takes precedence over port priority (page 4-164).
