The stp pvid-consistency protection mode command configures a protection mode for PVID inconsistency between directly connected ports in VLAN-based Spanning Tree (VBST).
The stp pvid-consistency protection mode command deletes the protection mode for PVID inconsistency between directly connected ports in VBST.
By default, no protection mode is configured for PVID inconsistency between directly connected ports. That is, the switch only prints log information when the PVIDs of directly connected ports are different.
Usage Scenario
VBST checks whether PVIDs of two directly connected ports are the same. If they are different, the processing method varies as follows:
If the protection mode is block, VBST will block the PVIDs.
If no protection mode is configured, VBST will print log information but not block the PVIDs.
Precautions
When the PVID of the interface is inconsistent and the PVID needs to be blocked, the stp pvid-consistency protection mode command must be configured on the two directly connected ports and their link types must be both trunk.
