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
Console(config)#spanning-tree priority 40000
Console(config)#
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. This method is based on the IEEE 802.1w Rapid
Spanning Tree Protocol.
short - Specifies 16-bit based values that range from 1-65535. This method is based on the IEEE 802.1 Spanning Tree
Protocol.

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 4-211)
takes precedence over port priority (page 4-213).
Example
Console(config)#spanning-tree pathcost method long
Console(config)#
