Licensing Requirements and Limitations for QinQ
Involved Network Elements
Other network elements are not required.
Licensing Requirements
QinQ is a basic function of the switch, and as such is controlled by the license for basic software functions. The license for basic software functions has been loaded and activated before delivery. You do not need to manually activate it.

Software version evolution: V100R001C00 -> V100R002C00 -> V100R003C00 -> V100R003C10 -> V100R005C00 -> V100R005C10 -> V100R006C00 -> V200R001C00 -> V200R002C50 -> V200R003C00 -> V200R005C00 -> V200R005C10 -> V200R019C00 -> V200R019C10
Feature Limitations
- Selective QinQ based on the VLAN ID can be only enabled on hybrid or trunk interfaces in the inbound direction.
- The outer VLAN ID must exist and the interface must be added to the outer VLAN in untagged mode.
- The interface learns the MAC address in the VLAN specified by the outer VLAN tag of packets.
- The MUX VLAN and selective QinQ based on the VLAN ID cannot be configured on the same interface.
- If only single-tagged packets from a VLAN need to be transparently transmitted, do not specify the VLAN as the inner VLAN for selective QinQ.
- If forwarding resources exceed the specifications, VLAN stacking can be configured. However, after the device restarts, the invalid VLAN stacking configuration may become valid and valid VLAN stacking configuration may become invalid.
- If VLAN stacking is configured on an interface corresponding to the VLAN, VBST negotiation for this VLAN will fail.
- QinQ cannot be used with features such as DHCP, ARP, and IGMP.
- Starting from V200R003C00, when original packets carry two or three VLAN tags and the device is configured with IPv6 VXLAN and VLAN stacking, tags in forwarded packets are incorrect. Please deploy VLAN stacking on the neighboring device.
- The original VLAN specified in the port vlan-stacking command cannot be the same as the outer VLAN configured on a QinQ Layer 2 sub-interface.
For the CE12800E equipped with FD-X series cards, no extra VLAN tag can be added to the original double-tagged packets, even if VLAN stacking is configured.
- M-LAG cannot be configured together with VLAN Mapping or VLAN Stacking.
