You helped me a lot to understand how the Netflow works. Good job.

great video covers and explains the netflow concept completely

tyvm for the notes included, saved me a ton of time creating my own notes

Excellent quality Ben.. thanks for sharing

Excellent video ⭐⭐⭐⭐⭐ Thank you for taking time to make this for us 🙏 👩‍💻

Thnx a lot , very helpful information

Awesome video!!! thank you boss!!!!

Great video that covers the topic in more detail than most other NetFlow videos. Am i right to assume that if I do not configure a sampler in a flexible netflow configuration, it will sample 1 out of 1 packets? Where can I confirm this? We currently have a flexible NetFlow configuration active without a sampler, but we suspect that not all packets are "reported" on a Cisco 3850 Catalyst switch.

Hi Ben Excuse me what is the difference between NetFlow v5 and v9 thanks

You have mentioned below commands for flexible netflow . flow exporter FNF_EXPORT destination 1.1.1.1 transport udp 9995 export-protocol netflow-v9What exactly is 1.1.1.1 here. I see in the diagram, it as some kind of a server. Please let me know

Is it possible to enable Netflow without a Netflow collector or server?

remembering "ip cache flow" = sounds a lot like ip cash flow and then you just make a quick mnemonic like "as long as there are cache flows you have cash flows"?. i dunno, i know that's terrible.

with V9 and flexible , you kind of mixed up
