Zusammenfassung:A network device for processing packets. The network device includes applying specific fields from a packet to an associated memory device and comparing means for comparing input to the memory device with entries in the memory device. The network device also includes enabling means for enabling selection of bits, by the memory device, that are required to match exactly with bits from the input to the memory device. The network device further includes outputting means for outputting an address for a matched entry by the memory device and applying means for applying a match from the memory device to an associated entry in a table for applying actions from the table that are associated with the match to the packet.
