Scenario Description Task

Configure basic QinQ

After basic QinQ is configured, the switch adds a public tag to incoming packets so that user packets can be forwarded on the public network.

Configuring Basic QinQ

Configure selective QinQ

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

Configuring Selective QinQ

Set the TPID value in an outer VLAN tag

This configuration allows a Huawei device to communicate with a non-Huawei device.
