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.

•
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.
•

This method is based on the IEEE 802.1 Spanning Tree Protocol.
Default Setting

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 4-170) takes precedence over port priority (page 4-171).
Example
Console(config)#spanning-tree priority 40000
Console(config)#
Console(config)#spanning-tree pathcost method long
Console(config)#
