SPANNING TREE COMMANDS

spanning-tree backup-root

This command adjusts the bridge priority in an attempt to take over as the new root bridge if it loses contact with the original root device. Use the no form to disable the command.

Syntax

[no] spanning-tree backup-root

Default Setting

Disabled

Command Mode

Global Configuration

Command Usage

This command will automatically lower the bridge priority of this device by 4096 if the switch loses contact with the current root bridge. For this command to succeed, the switch must have a direct connection to current root bridge, and its adjusted bridge priority must be higher (i.e., a numerically lower value) than all the other bridges in the spanning tree.

Example

Console(config)#spanning-tree backup-root

Console(config-mstp)#

spanning-tree mst-configuration

This command changes to Multiple Spanning Tree (MST) configuration mode.

Default Setting

No VLANs are mapped to any MST instance.

The region name is set the switch’s MAC address.

Command Mode

Global Configuration

Example

Console(config)#spanning-tree mst-configuration

Console(config-mstp)#
