Need help with network traffic analysis
Posted on 2014-10-02
What is the easiest way to ascertain which users on a network may be using large amounts of bandwidth?
I suspect one of the users is having high utilization at times and causing havoc with our VoIP calls. Actually I suspect the issue lies with the ISP but they refuse to acknowledge it. All of the vendors VoIP QoS settings are active in our router and the issue persists. Anyway I'm now down to seeing if it can be pinned on a user at this point.
This is not a domain environment. We have about 40 VoIP Phones, 40 workstations and various mobile devices. The switch is a CISCO SF200. I've gotten PRTG Traffic Grapher running and I've configured the switch to mirror traffic from the port that connects our router to port 48 which is connected to computer running PRTG. I think Im close to getting the info I need but not quite there yet..I guess what Im asking is "Is there a simpler way to be doing this that I'm overlooking?"
