Hi,
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.

Hello,
What netflow collector are you using? All information about flows will be sent to the collector so it depends on the netflow collector as to how it displays that data.
However you can probably do what you need from IOS. Try typing the following at the IOS prompt
sh ip cache flow
sh ip cache verbose flow
This should show you the current flows.
Thanks

I use NetFlow Analyzer from Manageengine.
Unfortunately it only generates web pages, and pictures... which is rather static.
I need real time statistics, like these: http://mcdouglas.dyndns.org/2009-02-12_1530.swf
Using the commands you mentioned will not get me port numbers, bw used, etc.
