qinq transparent-vlan
Use qinq transparent-vlan to enable transparent transmission for a list of VLANs on a port.
Use undo qinq transparent-vlan to disable transparent transmission for a list of VLANs on a port.
Syntax
qinq transparent-vlan vlan-id-list
undo qinq transparent-vlan { vlan-id-list | all }
Default
Transparent transmission is disabled for all VLANs.
Views

Parameters
vlan-id-list: Specifies a space-separated list of up to 10 VLAN items. Each item specifies a single VLAN ID or a VLAN ID range in the form of vlan-id1 to vlan-id2. The value range for VLAN IDs is 1 to 4094. The end VLAN ID must be equal to or greater than the start VLAN ID.
all: Specifies all VLANs.
Usage guidelines
By default, QinQ tags all incoming frames with the PVID on a port. This command disables QinQ to tag incoming traffic from a list of VLANs. These VLANs are called transparent VLANs.
You can repeat this command to add VLANs to the list of transparent VLANs.
To ensure successful transmission for a transparent VLAN, follow these configuration guidelines:
Set the link type of the port to trunk or hybrid, and assign the port to the transparent VLAN.
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, many-to-one, or one-to-two VLAN mappings.
Original or translated outer VLANs of two-to-two VLAN mappings.
Examples
# Configure HundredGigE 1/0/1 as a trunk port, and assign the port to VLAN 2, VLAN 3, and VLANs 50 through 100. Enable QinQ on HundredGigE 1/0/1, and configure the port to transparently transmit frames from VLAN 2.
