Traffic Load/Bandwidth on 2500 Series Router

[kmontgomery]

Hi Everyone. I have an older 2500 Series router that I use as a front end for a WAN link. I need to be able to monitor the traffic type, bandwidth usage on it and also I'd like to be able to graph bandwidth usage by destination address of all traffic crossing it... does anyone know of a tool that will assist me with this process? Can it be done through MRTG? If so, which method would you use to accomplish it?

All answers appreciated... thanks!

Hi,

you are asking too many things to an old tired 2500. What you want is called netflow and is supported on a bit more modern routers that have more memory to accommodate the needed IOS.

The one you have would be able to send SNMP traffic data to mrtg and that's it.

Hope this helps, please rate post if it does!

What router would you recommend, has to support 100Mbps or close to it link, it is for our Microwave link, connects direct to radio (and then regular ethernet on the other side) which runs at roughly 94Mbps once you take the overhead into account... the older 2500 runs fine with it.

Hi,

Be reassured that currently your 2500 is not handling 94 Mbps of traffic, as it is simply unable to do that :) The radio has a serial interface at which speed ?

However, I think said a 2801 or even a 1841 would do the job perfecly.

Yes, you are correct. I was incorrect in my logic on my network, confusing interfaces. I will be closing this topic but opening a new one. That one will focus on if I can make those measurements through a Catalyst 3548 or 3550 switch.

Thanks for all your input, sorry for the confusion.
