communicate under the same VLAN. Here is a special CPU port, which belongs to two VLAN, called TRUNK,SWC Hardware in the trunk port to send and receive data, must have Vlan_tag (802.1q). In the CPU system, because there is only one physical path, only software to achieve the VLAN partition (such as the VLAN under Linux). In addition, the WLAN is generally hung in the LAN, so in Linux you can use a virtual bridge device to connect the two devices. Her
