I'm an admin for a small company and we have a T1 for our internet connection.
When viewing SNMP graphs I see that our T1 is filled to capacity 80% of the day. We only have about 20 employees and the traffic should just consist of email, web traffic, and shell access.
I'd like to view statistics per local IP address on our router (2621). I'm still getting the hang of the Cisco thing but with Unix or Linux I'd be able to use something like iptraf to view these stats based on traffic usage to pinpoint the bandwidth hog. Can these stats be seen by the router and if so, how?
My last resort is to stick a Linux firewall in between the router and switch.
