Title: VIRTUAL LOCAL AREA NETWORK IMPLEMENTATION METHOD AND TERMINAL DEVICE
Abstract:
Disclosed are a virtual Local Area Network (LAN) implementation method and a terminal device. The method comprises: separately copying a layer 2 data stream packet entering from each LAN side port to each LAN side port; configuring a layer 2 firewall rule according to at least one preset virtual LAN and connectivity between the ports; and separately determining the layer 2 data stream packet needing to be forwarded or discarded within each of the virtual LANs according to the layer 2 firewall rule. The present invention achieves the functions of the virtual LANs without increasing hardware costs of the terminal device, and improves the compatibility of the terminal device. (FIG. 1)
