3.3 Configuring the QinQ VLAN This section describes how to configure the QinQ function working mode and apply to a port.

Context Virtual local area network (VLAN) is originally a virtual workgroup concept. It realizes the isolation between different workgroups in one switch and these workgroup share one switch. All users in VLAN can communicate with each other, but the number of VLANs is limited to 4096. For a single access switch, 4096 VLANs are completely enough. But for a large layer-2 network, 4096 VLANs are obviously not enough. The QinQ is proposed to dissolve the VLAN limitation. The QinQ technology is also called the Stacked VLAN or Doubled VLAN. This technology complies with the IEEE 802.1ad standard. It encapsulates the user private network VLAN Tag in the public network VLAN Tag to make messages traverse the backbone network (public network) of carriers with two layers of VLAN Tags. In public networks, messages are transmitted only according to the external VLAN Tag (namely the public network VLAN Tag) and the private network VLAN Tag is shielded.


User Guide


Technically, the QinQ completely supports multi-layer stacking without limitation. It is only restricted by the length of the Ethernet message. So, the QinQ features excellent expandability. QinQ has many different names in the industry, including Tag in Tag, VLAN VPN, StackVLAN and SVLAN.

The QinQ technology can mainly solve the following problems:

Easing the increasing deficiency of public network VLAN ID resources User can plan their own private VLAN IDs and will not conflict with public network

VLAN IDs Providing small-sized metropolitan area networks (MANs) or enterprise networks with a

relatively simple layer 2 VPN solution

Parameter Description Table 3-1 Parameters of the QinQ VLAN page

Parameter Parameter Description

Port Ports of the OT928G, including four 10/100BaseT ports and one 100/1000BaseT port.




QinQ Status QinQ VLAN status. Control the QinQ VLAN function on the user side On: When the port receives an Ethernet frame, no matter whether the Ethernet frame contains the VLAN Tag or not, the OT928G will label the Ethernet frame with the VLAN Tag of the port default VLAN. (If the frame is received tagged, the 802.1p priority of the original tag will be used in outer VLAN tag instead of using the port default priority.(see Table 4-8 Processing of the received upstream Ethernet frame in various QinQ statuses)

In this way, if the received message has already contained a VLAN Tag, the Ethernet frame will become a double-tagged Ethernet frame. If the received Ethernet frame is untagged, it will become a single-tagged Ethernet frame with the default VLAN Tag of the port. Off: When the port receives an Ethernet frame, the OT928G will only add the port default VLAN to the untagged Ethernet frame or replace the VLAN id of priority-tagged frames with default VLAN id. In other words, the OT928G will never add a VLAN Tag to the received tagged Ethernet frame. Default value : Off

3.4 Configuring the Forced Priority Setting This section describes how to configure the forced priority for a GE or FE port.

Context When the GE or FE port is used, you must configure the parameters on the Web page depending on whether you trust the device connected to the GE or FE port or not.
