Procedure

Cause 1: The VBST function was disabled on the peer device.
1. Run the display stp [ vlan vlan-id ] [ interface interface-type interface-number | slot slot-id ] [ brief ] command to check whether VBST is disabled on the interfaces that are directly connected.
  - If VBST is disabled on the interfaces that are directly connected, go to Step 2.
  - If VBST is enabled on the interfaces that are directly connected, go to Step 3.
2. Run the stp vlan vlan-id1 enable command in the interface view to enable VBST. Then, check whether the log persists. If the log persists, go to Step 3.
3. Collect trap, log, and configuration information, and contact technical support personnel.
Cause 2: The links connected to the peer were congested.
1. Check whether the link is congested between the local device and the neighbor device.
  - If the link is congested, go to Step 2.
  - If the link is not congested, go to Step 3.
2. Repair the physical link and then check whether the log persists. If the log persists, go to Step 3.
3. Collect trap, log, and configuration information, and contact technical support personnel.
