We recently installed the netflow module and it appears to be working without any issues. It is gathering data. One question I did have...For a 12 hour period it is showing that a total of 55 GB of SMTP traffic was passed, when I break that down it basically is telling me that I am using almost 10 Mbps as an average bandwidth consumption. It seems awfully high to me. I just want to be sure I am breaking the data down correctly.
