2. Specify VID 100 and 1000 in VLAN Group 1 and 2 respectively. Select TP, FX, and CPU as
member ports in VLAN Group 1 and 2 (when CPU is selected as a member, the VLAN
becomes management VLAN.).

Click “Apply” to make settings effective.
VLAN Per Port Setting
1. Check whether Q-in-Q is enabled. When enabled, settings in Egress Link Type will be
disabled. In this example, Q-in-Q is enabled; thus, this decision ignores Egress Link Type
settings.
2. Check whether you have set up 802.1Q VLAN Group Table. When incoming traffic is with a
tag, the forwarding process will be executed according to settings in 802.1Q VLAN Group
Table. In this example, 802.1Q VLAN Group Table has already set up.
Q-in-Q Configuration
1. By default, Q-in-Q is disabled. Make sure Q-in-Q is enabled before applying the settings.
2. Enter the TPID to identify the frame as the IEEE 802.1Q-tagged frame. The value is usually
set to 8100. However, you can also enter the TPID (such as 88A8, 9100) that is suitable for
your networking environment.
3. Enter the outer VLAN ID. In this example, the outer VLAN ID is 1000.
4.
Decide to add a double tag to or remove a double tag from egress traffic. In this example, “FX
Add QinQ Tag, TP remove Tag” is selected to accomplish the process of the provided
scenario (Egress traffic from FX port has already had a tag with VID 100. The other tag with
VID 1000 will also be added).
