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 (QinQ and Dot1q on a subinterface) 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.

Version Requirements

Feature Limitations

  • Only E series cards, X series cards, F series cards, SC cards among S series cards of the S7700&S9700 support the termination sub-interface. Starting from V200R007C00, X1E cards among X series cards 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.
  • Add member interfaces to an Eth-Trunk before configuring termination sub-interfaces on the Eth-Trunk. 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 VLANs 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 a maximum of 128 VLANs be in all VLAN ranges.
  • VLAN termination sub-interfaces cannot be created on a VCMP client.
  • If 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 a super-VLAN 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.
