Hello,
you can use netflow or RMON. If the station is connected to the single port (not shared) you cal also use SNMP. NetFlow gives you the most information (src/dst IP, ports, time, bytes/pck, protocol, src/dst AS). If you want to know more about netflow see cisco web pages or
our pages: http://netflow.caligare.com/ http://support.caligare.com/ or contact me directly.
Kind regards,
Jan
