A monitor for packets on a local area network includes a set of logic circuits implemented in a computer chip, a memory interacting with the computer chip to provide monitoring data to the logic circuits, logic for receiving a packet from the local area network, and a parser to process bits of the packet as they are received, wherein the parser uses the monitoring data in conjunction with the received bits to provide forwarding data which indicates the type of packet received. The monitor uses the forwarding data to determine whether the received packet is stored in memory, discarded, or forwarded to other host computers in the network. The monitor uses type information from the forwarding data to maintain count information of the different types of packets which may be forwarded to a host computer or a remote monitoring device.
