Our company is looking to get some bandwidth monitoring software to keep track of what our usage is. A lot of our divisional buildings connect back to our corporate office through T-1. They all have some sort of Cisco router (older 1601's in most). I was wondering what some other people were using. I've looked into a few options but most of them need to have the router send info off to the server or client doing the monitoring and most of ours aren't supported. While we certainly don't mind paying for it, our boss also doesn't want to spend a ton of cash on it either. Any ideas or tips would be great.
