Is there a free tool out there or a command i can use on my cisco switch to monitor the usage on each port? This is what i want to accomplish. I want to see which IP Address or computer name is using the most network bandwidth.
 
MRTG will be your friend here. I use it on all my switches and works a treat.

MRTG won't help much the IP address breakdown but will show historical port utilisation.

If you need that level of IP info, you may be looking at something that can analyse Cisco Netflow stats - something like cflowd perhaps..

 
Hi,

I would suggest the Cisco Network Assistant, I think it does what you are after, but I havn't used it in a year or so....


Hope it helps,

Brett

From your original comments about wanting to know which IP address or computer name is using the most bandwidth you are looing at the features available with NetFlow Data Exporting. The problem with NetFlow is it doesn't work on the lower-end fixed-configuration switches. You need a minimum of a Catalyst 4500 with a Supervisor IV or V with the Netflow Services Card (WS-F4531) or a Supervisor V-10GE (Netflow is built-in). The Netflow commands are available in the stackable switches but they don't actually work.

You say you want to see who is using the most bandwidth - do you mean just within your network (your switch?) or do you mean out to the Internet? If you mean out to the Internet then it is possible you could enable Netflow on your router, since most Cisco routers support NetFlow. Can you describe your environment more?
