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.

Format

port trunk pvid vlan vlan-id

undo port trunk pvid vlan

Parameters

Parameter	Description	Value
vlan-id	Specifies the default VLAN ID of a trunk interface.	The value is an integer that ranges from 1 to 4094.

Views

Ethernet interface view, GE interface view, XGE interface view, 25GE interface view, 40GE interface view, 100GE interface view, MultiGE interface view, VE interface view, Eth-Trunk interface view, port group view

Default Level

2: Configuration level

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.

Follow-up Procedure

Add the trunk interface to the default VLAN.

Precautions

If the ID of a nonexistent VLAN is configured as the PVID, VLAN 1 is added to the untagged packets. After the PVID is configured globally, the PVID of the interface is changed to the configured one.
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.

Example

# Specify VLAN 5 as the default VLAN of GE0/0/1.

<HUAWEI> system-view
[HUAWEI] interface gigabitethernet 0/0/1
[HUAWEI-GigabitEthernet0/0/1] port link-type trunk
[HUAWEI-GigabitEthernet0/0/1] port trunk pvid vlan 5
