How can I know how much bandwidth is consumed by each station on my LAN? I familiar with methods such as NBAR, NetFlow and IP Accounting but none of them provide that particular information. NBAR tells me what applications are running, NetFlow show me which IP is trying to connect to which IP and how many bytes was sent and IP Accounting shows similar information to NetFlow.
But, when some station on my LAN flooding the connection, NBAR is recognizing that somebody is using p2p on the LAN how can I find out which station is actually doing this? I guess that all that comes down to the question how much bandwidth is consumed by each station (hopefully ? station + protocol) but what tool can tell me that?
p.s. btw, if there is some 3-rd party tool (i.e. not performed by Cisco router) that can answer that question I?d like to know about it too ? software or hardware based.
Thanks in advance,
