Hi,

5.5  Configuring QinQ

This section describes how to configure QinQ.

5.5.1  Configuring Basic QinQ

Basic QinQ enables the device to add a public tag to incoming packets so that user packets can be forwarded on the public network.

Background

To separate private networks from public networks and conserve VLAN resources, configure double 802.1Q tags on QinQ interfaces of the device. Inner VLAN tags are used on internal networks and outer VLAN tags are used on external networks. QinQ expands VLAN space to 4094x4094 VLANs and allows packets on different private networks with the same VLAN IDs to be transparently transmitted.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    vlan vlan-id

    A VLAN used on the public network is created.

  3. Run:

    quit

    Exit from the VLAN view.

  4. Run:

    interface interface-type interface-number

    The interface view is displayed.

    The interface can be a physical interface or an Eth-Trunk interface.

  5. Run:

    port link-type dot1q-tunnel

    The link type of the interface is set to Dot1q-tunnel.

    By default, the link type of an interface is access. Dot1q-tunnel interfaces do not support Layer 2 multicast.

    The device cannot use a Dot1q-tunnel interface to connect to a TRILL network.

  6. Run:

    port default vlan vlan-id

    The VLAN ID of the public VLAN tag, that is, the default VLAN of the interface, is configured.

    By default, VLAN 1 is the default VLAN of all interfaces.

  7. Run:

    commit

    The configuration is committed.

Checking the Configuration

  • Run the display current-configuration interface interface-type interface-number command to check the QinQ configuration on the interface.

5.5.2  Configuring Selective QinQ

Context

Selective QinQ enables the device to add different outer VLAN tags to received data frames according to VLAN IDs in the frames.

imgDownload?uuid=274bf8edd68a446bb006fb3 NOTE:
  • Selective QinQ 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 cannot be configured on the same interface.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    interface interface-type interface-number

    The interface view is displayed.

  3. Run:

    port link-type hybrid

    The link type of the interface is configured as hybrid.

    By default, the link type of an interface is access.

  4. Run:

    port hybrid untagged vlan vlan-id

    The interface is added to the VLAN in untagged mode.

    The VLAN ID specified by vlan-id must already exist on the device. The original VLAN can be not created.

  5. Run:

    port vlan-stacking vlan vlan-id1 [ to vlan-id2 ] stack-vlan vlan-id3

    Selective QinQ is configured.

    imgDownload?uuid=4cb802b50fd840d384fe156 NOTICE:

    If the port vlan-stacking command has been executed at least three times with specified VLAN ranges and VLAN ranges are combined twice at least, the configuration of each command must be committed. Otherwise, packets may be lost. For example, when port vlan-stacking vlan 30 to 60 stack-vlan 100, port vlan-stacking vlan 20 to 30 stack-vlan 100, and port vlan-stacking vlan 60 to 70 stack-vlan 100 commands are used, VLAN ranges 20 to 60 and 20 to 70 are combined twice. Therefore, commit the configuration of each command.

  6. Run:

    commit

    The configuration is committed.

Checking the Configuration

  • Run the display current-configuration interface interface-type interface-number command to check the configuration of selective QinQ on the interface.
