There are a couple of things you will need to do whether you use tools to 
capture information or write your own code.  The device will need to have some 
sort of shell access and tools built in to packet capture.  If its a OS X, BSD, 
Linux machine you will be able to use tcpdump.  You can send that capture to a 
file and process with a tool.  I would recommend Wireshark.  Wireshark can 
capture as well but if the machine can’t run it or doesn’t have a gui you will 
need to capture and then process on your machine.  If the device is fairly 
locked down you’ll need to mirror the switch port its connected to.  On the 
mirrored port you can use Wireshark, tcpdump, or your own code to do a capture.
