Abstract
A program product comprising program instructions, embodied on a storage medium that are operable to cause a processor to switch input data packets for ingress to at least one internal-device port of an internal device from all external ports using virtual local area network identifiers and port virtual local area network tags and to switch output data packets for egress from the internal-device ports of the internal device using the virtual local area network identifiers and the port virtual local area network tags. There are more external ports than internal-device ports and applications in the internal device have visibility to all external ports.
