I'm looking for suggestions on the best and easiest way to monitor who on my network is using alot of the network bandwidth and what they are doing. I realize there are many ways to do this so feel free to suggest any way you may have implemented this.
The network setup is
2 user access switches ==> core switch ==> mpls ==> core switch ==> firewall ==> internet
I am really interested in find out from the user access switches the bandwidth hogs and what they are doing. Is there anyway of getting aorund this process: Identify via graph what ports on user access switches are using most traffic and put a port mirror to capture and analyze that traffic.
