port trunk pvid vlan
Function
The port trunk pvid vlan command specifies the default VLAN for a trunk interface.
The undo port trunk pvid vlan command restores the default VLAN of a trunk interface to the default setting.
By default, VLAN 1 is the default VLAN of trunk interfaces.
Usage Guidelines
Usage Scenario
An interface may receive untagged and tagged frames, but the device processes only tagged frames. Therefore, the device adds a tag to each untagged frame received by an interface. The default VLAN ID of the interface can be added to untagged frames so that these frames are forwarded in the default VLAN.
Prerequisites
The VLAN to be specified as the default VLAN has been created.
Follow-up Procedure
Add the trunk interface to the default VLAN.
Precautions
The port trunk pvid vlan command only specifies the default VLAN of a trunk interface but does not add the trunk interface to the default VLAN. A trunk interface forwards frames with the default VLAN ID only after it is added to the default VLAN using the port trunk allow-pass vlan command.
If you run the port trunk pvid vlan command multiple times in the same interface view, only the latest configuration takes effect.
