Command Usage
Bridge priority is used in selecting the root device, root port, and
designated port. The device with the highest priority (i.e., lower
numeric value) 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
spanning-tree pathcost method { long | short }
no spanning-tree pathcost method
• long - Specifies 32-bit based values that range from 1-200,000,000.
• short - Specifies 16-bit based values that range from 1-65535.
Default Setting
Long method

Global Configuration
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 4-218) takes precedence over port priority
(page 4-219).
