VBST Configuration
This chapter describes how to configure the VLAN-based Spanning Tree (VBST). VBST is a spanning tree protocol developed by Huawei. It constructs a spanning tree in each VLAN to load balance traffic from different VLANs, improving link use efficiency.

- Applicable Scenario
- Configuration Task Summary
- Licensing Requirements
and Limitations for VBST
- Default Configuration
- Configuring Basic VBST Functions
After you configure the operation mode of VBST and start VBST, VBST calculates the spanning tree and prunes a network into a tree network to eliminate loops. Network planners can also set parameters such as the switch priority, port path cost, and port priority to adjust the spanning tree calculation result. - Setting VBST Parameters That Affect VBST Convergence
After basic VBST functions are configured, VBST implements fast convergence using default parameters. To achieve better convergence, set parameters that affect VBST convergence. - Configuring Protection Functions of VBST
VBST provides BPDU protection, TC protection, root protection, and loop protection, and you can configure one or more protection functions as needed. - Setting Parameters for Interworking Between a Huawei Datacom Device and a Non-Huawei Device
To implement interworking between a Huawei datacom device and a non-Huawei device, configure the fast transition mode according to the Proposal/Agreement mechanism of the non-Huawei device. - Maintaining VBST
