What would be the best tools to put into place to monitor bandwidth issues on a network? Specifically the problems that we are having are slow internet connections with pages sometimes timing out, etc. I need a way to monitor this to try to find out what the real issues are.
We have a small network, a couple 1800 routers each with a T1 line. One for data and one for voice. We have a few catalyst switches and use vlans to seperate the voice from the data traffic. We use a Cisco ASA 5505 on the data network.
Let me know any info that I'm leaving out that you need. Thanks for your help.
