There are several good bandwidth monitoring tools available. NetFlow Analyzer allows you to monitor bandwidth by application. Bandwidth usage per application gives you instant visibility into which applications are using up maximum bandwidth.

WhatsUp Gold 12.0 is another one thats popular.

CNA Cisco network assistant would also be helpful

Hi chrisa123,

Thanks for the reply. I have read you link and it says that it will not support Cisco 3500 so I can't use it. I have tried the Cisco Network Assistant and it's great but I still want something that CNA can't handle, calculating the bandwidth based on the protocol used. It would be much easier to monitor the bandwidth knowing the protocol it uses. Hope you know a bandwidth meter that I can used.

Inorder to monitor the bandwidth of each applications we can use the inbuilt functions of a router rather than external tools.

1. Find what the is the IP address and port number of the servers or computer in your organisations

2 Create access-lists matching teh same

3. Create a class-maps and policy-map to set some dscp values in the ingress

4. Create one more policy-map and class-map matching the dscp values and do not mention any bandwidth commands.

5. apply the policy-map in the egress

6. During peak business hours, give teh following command

sh policy-map int X/Y(Egress port)

check for the offered rate for each class which will give you the required bandwidth details.

If you want to apply a limit for bandwidth,

apply the police command on the egress policy-map.

I hope it helps.

Thanks and Regards,

Hi Naidu,

Can I have a little background with your network setup and the Cisco Devices your company is using?
