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.

port trunk permit vlan
{
vlan-id-list
|
all
