Licensing Requirements and Limitations for VLAN Termination
Involved Network Elements
Other network elements are not required.
Licensing Requirements
VLAN termination, that is, QinQ and Dot1q on a sub-interface, is often used on an MPLS network, so the device must be enabled with MPLS. MPLS requires a license. By default, MPLS of a newly purchased device is disabled. To use MPLS, apply for and purchase the license from the equipment supplier. VLAN termination itself can be used without a license.

Feature Limitations
On the S12700, only E series, X series, and SC cards of S series cards support termination sub-interfaces. Starting from V200R007C00, X1E cards among X series support termination sub-interfaces. For details, see the card classification in Hardware Description.
- Termination sub-interfaces cannot be configured on an Eth-Trunk member interface.
- You are advised to add member interfaces to an Eth-Trunk and configure termination sub-interfaces on the Eth-Trunk in sequence. Termination sub-interfaces can be configured successfully on an Eth-Trunk only when all series of cards where member interfaces reside support termination sub-interfaces.
- The VLAN IDs terminated by a sub-interface cannot be created in the system view or be displayed using a display command.
- In V200R005 and earlier versions, When VLAN IDs terminated by a sub-interface are used for Layer 3 forwarding, only the first VLAN takes effect even if multiple inner VLAN IDs are specified.
- When VLAN IDs terminated by a sub-interface are used for Layer 3 forwarding, it is recommended that 128 VLANs be in all VLAN ranges.
- VLAN termination sub-interfaces cannot be created on a VCMP client.
- When the dot1q termination vid or qinq termination pe-vid ce-vid command is used to configure a VLAN for the VLAN termination sub-interface, the VLAN cannot be configured as the super-VLA or sub-VLAN.
If the PW-side interface is a Layer 3 interface switched by the undo portswitch command, the AC-side interface cannot be a Layer 3 interface or subinterface belonging to a Layer 3 interface; otherwise, traffic forwarding is abnormal.
