>  The LAN station monitor (Ethernet station monitor on versions prior to
  1.3.0) discovers MAC addresses and displays statistics on the number
  of incoming, and outgoing packets. It also includes figures for incoming
  and outgoing kilobits per second for each discovered station.</P
><P
>  The entry above each line of statistics is the station's LAN
  type (Ethernet, PLIP, Token Ring, or FDDI) and the hardware MAC address.
  Each statistics line consists of the following information:</P
