Spanning Tree Commands 4

Default Setting

Command Mode

Global Configuration

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.

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 4-154)takes precedence over port priority (page 4-155).

Example

Console(config)#spanning-tree pathcost method long

Console(config)#

4-149
