Strict Virtual Wire mode: Packets can only be transmitted between Virtual Wire interfaces, and the VSwitch cannot operate in Hybrid mode.
Virtual Wire operates in two modes, which are Strict and Non-Strict mode respectively, as detailed below: Furthermore, controls of policy rules or other functions are still available when Virtual Wire is used. The two connected subnetworks can communicate directly on Layer 2, without any requirement on MAC address learning or other sub network's forwarding. With this function enabled and Virtual Wire interface pair configured, two Virtual Wire interfaces form a virtual wire that connects the two subnetworks attaching to Virtual Wire interface pair together. System supports VSwitch-based Virtual Wire. Introduction to Virtual Wire Introduction to Virtual Wire
