Hello Experts,

I am looking for a way to identify which computer(s) is saturating our T1. Yesterday, on more than one occasion, we experienced complete saturation resulting in short periods of downtime.

The network is comprised of:

Cisco 1841 Router
Juniper NetScreen-25
Cisco Catalyst 2960
2 Wireless Access Points
and various (roughly 60) wireless and wired computers/servers (running XP, 2003, and Mac OS X)

I'm looking for a way to monitor and discover which computer is using all of the bandwidth (preferably open source, but commercial is not a problem). Any advice regarding tools/nex steps would be greatly appreciated.

Thanks much!

NetScreen allows with a hidden command to create a short-term profile. You need several steps to accomplish that, I will elaborate on it if you like.

Depending on the IOS on the router and how your network is connected to your router, you can also use NetFlow on the router to show top-talkers. Check out example-config here:
