Run Wireshark on the NTA collector to sniff UDP port 2055 from the IP address of your Loopback1 interface, just to make sure you're getting NetFlow packets from the 6506 exporter.
If that's the case, my first guess would be that your template doesn't match one of NTA's built-in templates exactly. Check the NTA documentation to verify your template configuration.
I am getting the error that template is not matching. What can i do else to match that template .
I don't know; your record looks OK to me, but I haven't used custom records with NTA before. If your code supports it, maybe you should try changing to classic NetFlow v5 or v9 config. The other thing that looks a little strange to me is that you're exporting a sampler table--maybe try removing that?
Check the NTA administrator guide. It has lots of details on this. The template requirements start on page 23. Or you could always start a support ticket.
At this point you may just want to get a ticket open with support and upload a pcap of your traffic to see if they can assist you in why your template is not being processed.
I use the above configuration on routers, but I continue to use the traditional v5 configuration on my 6500s. Like you, I was unable to find the correct custom configuration to work on a 6500.
ip flow-export source Lookback0
ip flow-export version 5
ip flow-export destination <NTA server IP> 2055
ip flow ingress
ip flow egress !(if needed)
thanks all let me try this ...
