Our customer would like to use DNAC as simple netflow collector, similarly as it would work with Prime Collector license.
My understanding:
So, does that mean that Prime Collector like behaviour is not achievable with DNAC, only Application Telemetry, but for that Advantage license is needed?

Hi Flavio,
thank you for your response!
In my understanding Enable Application Telemetry works only with DNA-Advantage, as that is not a simple FNF but uses AVC(and AVC needs DNA-Advantage).
I just tested this on a 9300 with DNA Essential with the following result:
From this I assume that DNAC is only capable to process and visualize netflow records configured with the DNAC AVC netflow template, including AVC information(which is not supported by DNA-E license).
Or is there any other place in DNAC where I can see/analyse the basic netflow data received from the switch?
kind regards,
Gabor

Hello @gabori
Actually DNAC can act as netflow collector:
Step 4 |
In the NetFlow area, do one of the following:

And Netflow is available in both license level:

Maybe too late for my answer, but i will anyway. I`m interested.
The licence matrix says with Essential DNA license full flexible netflow is supported (https://www.cisco.com/c/m/en_us/products/software/dna-subscription-switching/en-sw-sub-matrix-switching.html). But AVC is only supported with Advanced.
So I guess netflow collected by DNAC with essential license would be for basic monitoring of the applications like AAA, DNS and DHCP. And for full application visibility AVC must be active on switches, so Advanced licencing is required and DNAC will have the Application Experience visibility.
DNAC is not a full netflow collector to avoid using it with legacy or third party devices (https://community.cisco.com/t5/networking-knowledge-base/faq-catalyst-center-third-party-device-visibility/ta-p/4910315#toc-hId--2117898411)
Answer: No, NetFlow needs to be collected from the device for this operation, which is not currently designed for Third-Party devices.
