We have setup netflow of a cisco ASR1002 router and we still cannot get the data displayed on NTA.
It shows Data is not available.
How do we get this to display?
If NTA receives viable packets from an IP monitored with NPM then it should just automatically add them to the list. Any chance you could throw wireshark on your orion server and confirm that it is seeing the netflow packets from the ASR? If you are getting them, does it show as coming from the same host IP as the one you use to monitor the router? If it was an unmonitored interface there would be an alert near the top of the menu bar indicating that it was getting flows from unmonitored interfaces and you would need to add them.
I agree with @mesverrum
Check also that traffic is not being blocked by firewall or something else. And post up your netflow config from the ASR.
