port default vlan

port default vlan


The port default vlan command configures the default VLAN of an interface and adds the interface to the VLAN.

The undo port default vlan command restores the default VLAN of an interface to the default setting.

By default, VLAN 1 is the default VLAN of all interfaces.


port default vlan vlan-id

undo port default vlan






Specifies the ID of the default VLAN.

The value is an integer that ranges from 1 to 4094.

Usage Guidelines

Usage Scenario

All frames sent from a user device are untagged, and frames sent from a remote device may also be untagged. However, the AP processes only tagged frames. Therefore, the AP 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.

After the default VLAN is specified for an access interface, packets passing through the interface are processed as follows:
  • When the interface receives an untagged frame, it tags the frame with the default VLAN tag.
  • When the interface receives a tagged packet:
    • If the interface is an access interface, it compares the VLAN ID of the packet with the default VLAN ID. If they are the same, the interface forwards the packets; otherwise, the interface discards the packets.
  • Before forwarding a tagged packet, the interface removes the VLAN tag from the packet.


The VLAN to be configured as the default VLAN has been created.

The interface type is access. If not, run the port link-type command to change the interface type.


You can also run the port command in the VLAN view to configure the default VLAN of an interface. The two commands have the same function.

A super VLAN cannot be configured as the default VLAN of interfaces.

If you run the port default vlan command multiple times in the same interface view, only the latest configuration takes effect.


# Configure VLAN 3 (an existing VLAN) as the default VLAN of GE0/0/1 (an access interface).

[Huawei] interface gigabitethernet 0/0/1
[Huawei-GigabitEthernet0/0/1] port link-type access
[Huawei-GigabitEthernet0/0/1] port default vlan 3
