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.
Pre-configuration Tasks
Before configuring basic VBST functions, complete the following task:
- Connecting ports and setting the physical parameters of each interface to make the physical layer in Up state (see Basic Configuration for Interfaces and Ethernet Interface Configuration in CloudEngine 12800 and 12800E Series Switches Configuration Guide - Interface Management)
- (Optional) Configuring the Root Bridge and Secondary Root Bridge
- (Optional) Setting the Device Priority
- (Optional) Setting the Path Cost for a Port
- (Optional) Configuring Port Priorities
- (Optional) Manually Configuring the Mapping Between MSTIs and VLANs
- Enabling VBST
- Verifying the Configuration of Basic VBST Functions
