Abstract

This document describes tools that forward data packets having tags conforming to different formats. In one embodiment, the tools receive a data packet on each of a plurality of ports, each data packet comprising a tag conforming to a different format. The tools relay the data packets to a port capable of transmitting tags conforming to a plurality of formats. In another embodiment, the tools receive a plurality of data packets on a source port comprising a plurality of logical source ports, each of which is associated with a unique tag. At least one data packet is received on each logical source port. Each data packet includes the tag associated with the logical source port on which the data packet is received. The tools map each data packet to one of a plurality of virtual switches based on the logical source port on which the data packet is received.
