Hello,

I think you need to enable netflow v-9:

flow exporter netflow-to-orion
destination <IP>
export-protocol netflow-v9
transport udp <Port>
template data timeout 60

Also, make sure 'ip cef' is enabled on your device.

You have the 1G Network Module (NM) installed - I believe you need the 10G Service Module (SM) for Flexible NetFlow:
