Parameters
Parameter Name
Parameter Meaning
[vlan-id]
Indicates the VLAN ID.
[port-name]
Indicates the port name.

The network topology changed.
Procedure
View physical devices on the network to check whether a
new physical link that has VBST enabled is added.
If a new physical link that has VBST enabled is added, go to Step
2.
If no new physical link that has VBST enabled is added, go to
Step 3.
Check whether the added physical link is necessary.
If the added physical link is necessary, go to Step 3.
If the added physical link is unnecessary, go to Step 4.
Run the display stp [ vlanvlan-id ] [ interfaceinterface-type
interface-number | slotslot-id ] [ brief ] command
to check whether the interfaces are consistent with the VBST calculation
results.
If the interfaces are consistent with the VBST calculation results,
no action is required.
If the interfaces are inconsistent with the VBST calculation results,
go to Step 5.
Correctly deploy the network topology, and then check whether
the log persists. If the log persists, go to Step 5.
Collect trap, log, and configuration information, and contact technical support personnel.
