The configuration on Switch B is similar to that onSwitch A and is thus omitted.z The port configuration on Switch B is only an example for a specific network requirement. The keyto this example is to enable the ports to receive and forward packets of specific VLANs. So you canalso configure the ports as trunk ports. Refer to VLAN Configuration for details.z A selective QinQ-enabled device tags a user packet with an outer VLAN tag regardless of theVLAN tag of the user packet, so there is no need to configure user VLANs on the device.z Make sure the packets of the default VLAN of a selective QinQ-enabled port are permitted on boththe local port and the port connecting to the public network.
