You can configure an IP address for an interface with VLANs. Any untagged traffic goes to the base interface (physical port) and the tagged traffic goes to the respective VLAN.
You cannot bring down the base interface that is configured to receive tagged and untagged traffic. You must bring down all VLANs on the base interface before you bring down the interface. However, you can delete the IP address of the base interface.
When you configure a VLAN using GVRP, the GVRP packets are sent as both tagged and untagged from the native VLAN.
For information about reverting with a configuration for receiving tagged and untagged frames on the same network interface, see the Data ONTAP Upgrade and Revert/Downgrade Guide for 7-Mode.
