Once the changes in the configuration are made, please apply the Flow monitor “ip flow monitor NFAmonitor input” to all the L3 interfaces to get the correct traffic information.

Once you have configured the Cisco ASR 1000 Series router to export NetFlow, NetFlow Analyzer will generate reports in a matter of minutes. You can download a 30-day trial here.
