The device is configured for sampled netflow, but it is not sending the samplerate in the netflow packets, so the harvester does not know the netflow is sampled or what rate.
Bob is this still an issue at this point?If you are using Netflow v9 we should be able to get a Samplerate field seen in a pcap. With most devices if that sample rate field is sent correctly, NFA will honor that sample rate without having to set an override.
