Zusammenfassung:	A network switch apparatus, includes: a network port configured to receive a packet; instrument ports configured to communicate with respective network monitoring instruments; a packet duplication module configured to copy the packet to provide multiple packets that are identical to each other: a tagging module configured to tag the multiple packets with different respective identifiers to obtain tagged packets; and a processing unit coupled to the instrument ports; wherein the processing unit is configured to determine whether a first one of the tagged packets satisfies a first criterion, whether a second one of the tagged packets satisfies a second criterion, process the first one of the tagged packets in a first manner if the first one of the tagged packets satisfies the first criterion, and process the second one of the tagged packets in a second manner if the second one of the tagged packets satisfies the second criterion.
