Disabling inconsistent PVID protection
About inconsistent PVID protection
In PVST, if two connected ports use different PVIDs, PVST calculation errors might occur. By default,
inconsistent PVID protection is enabled to avoid PVST calculation errors. If PVID inconsistency is
detected on a port, the system blocks the port.
Restrictions and guidelines
If different PVIDs are required on two connected ports, disable inconsistent PVID protection on the
devices that host the ports. To avoid PVST calculation errors, make sure the following requirements
are met:
•
Make sure the VLANs on one device do not use the same ID as the PVID of its peer port (except
the default VLAN) on another device.
•
If the local port or its peer is a hybrid port, do not configure the local and peer ports as untagged
members of the same VLAN.
•
Disable inconsistent PVID protection on both the local device and the peer device.
This feature takes effect only when the device is operating in PVST mode.
Procedure
1.
Enter system view.
system-view
2.
Disable the inconsistent PVID protection feature.

By default, the inconsistent PVID protection feature is enabled.
