Licensing Requirements and Limitations for VLAN Termination

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.

Software Requirements

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.
  • 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.
