I have a Cisco 871. How can I monitor who is using the internet in a given time?
I know I can install a netflow monitor, but that will only generate me graphs for daily, monthly, hourly usage.
I need something like the linux iftop utility: http://www.ex-parrot.com/~pdw/iftop/iftop_normal.png
Sometimes internet connection is really slow, and I have to figure out who is using it. I'd like to check who is using the net when I'm experiencing slowdowns.
