Methods and apparatus are disclosed for applying network policy to communications originating at operating system virtual interfaces. In an example embodiment, a network device is networked with a switch. The network device may include a first operating system interface, a virtualization adapter, and an input output port. In an example embodiment, the virtualization adapter receives a first frame from the first operating system interface. The virtualization adapter may tag the first frame to indicate an association between the first frame and the first operating system interface. The first frame may then be transmitted with a second frame being associated with a second operating system interface, to the switch via the input output port. In an example embodiment, the switch is configured to receive the frame, examine a tag and then to enforce a network policy upon the first frame, based on the tag.
