Abstract
A networking system includes a plurality of ports, each adapted to send and receive data. A switch core has a first channel configured to receive a logical input flow from each of the plurality of input ports, and has a second channel configured to receive a raw input flow from each of the plurality of input ports. Each logical input flow is carried by its corresponding raw input flow. A plurality of port mirrors are selectable from the plurality of ports. Each of the plurality of port mirrors is configured to produce a duplicate copy of at least one of the logical input flow and the raw input flow available at a selected port.
