Hi Anupam,


You can use netflow to identify the per host bandwidth consumed on your link.

Thanks Anupam,

is there any way instead of using the third party tool like netflow etc.

Hi Faiz,

For user level visibility you need NetFlow. If you do not want to opt for a 3rd party NetFlow tool and still see the results on the top users (IP Address), enable NetFlow on the interfaces and use the "IP TOP TALKERS" option if your router supports it.

After enabling NetFlow on the interfaces, for IP TOP TALKERS, config as below.

ip flow-top-talkers

top [number]                   Number of top talkers to be shown. Max is 200.

sort by [bytes | packets]   Sort based on volume or packets

cache-timeout [milliseconds]  How long top talkers info should be stored. Max is 3,600,000 milliseconds (1 hour).
