Usage Guidelines

Use this command in a topology with hybrid switches (for example, a virtual port channel [vPC] connected to a non-vPC switch) to configure VLAN-based load balancing.

To meet the VLAN-based load-balancing criteria, you must configure a different Spanning Tree Protocol (STP) bridge priority value for the root bridge and the designated bridge.

This command does not require a license.

Examples

This example shows how to enable Bridge Assurance globally on the switch:

switch# configure terminal
switch(config)# spanning-tree pseudo-information
switch(config-pseudo)#
