{ Configure trunk port to allow packets from its PVID to pass through.
port trunk permit vlan { vlan-id-list | all }
By default, a trunk port allows packets only from VLAN 1 to pass through.
5. Enable QinQ on the port.
qinq enable
By default, QinQ is disabled on the port.
Configuring transmission for transparent VLANs
About transparent VLAN
You can exclude a VLAN (for example, the management VLAN) from the QinQ tagging action on a
customer-side port. This VLAN is called a transparent VLAN.
Restrictions and guidelines
• Do not configure any other VLAN manipulation actions for the transparent VLAN on the port.
• Make sure all ports on the traffic path permit the transparent VLAN to pass through.
• If you use both transparent VLANs and VLAN mappings on an interface, the transparent VLANs
cannot be the following VLANs:
{ Original or translated VLANs of one-to-one, one-to-two, and many-to-one VLAN mappings.
{ Original or translated outer VLANs of two-to-two VLAN mappings.
Procedure

2. Enter Layer 2 Ethernet interface view or Layer 2 aggregate interface view.
interface interface-type interface-number
3. Set the port link type.
port link-type { hybrid | trunk }
By default, the link type of a port is
access.
4. Configure the port to allow packets from the transparent VLANs to pass through.
{ Configure the hybrid port to allow packets from the transparent VLANs to pass through.
port hybrid vlan vlan-id-list { tagged | untagged }
By default, a hybrid port is an untagged member of the VLAN to which the port belongs
when its link type is
access.
{ Configure the trunk port to allow packets from the transparent VLANs to pass through.
port trunk permit vlan { vlan-id-list | all }
By default, a trunk port allows packets only from VLAN 1 to pass through.
5. Specify transparent VLANs for the port.
qinq transparent-vlan vlan-id-list
By default, transparent transmission is not configured for any VLANs.
