netflow

In this video I explain what netflow is, what problem it solves, configure BGP routing between two routers, configure netflow and show you how to SEE traffic traverse your routers. Visibility is goooood.

It is crystal clear for us to understand the whole picture by showing us the detailed topology diagram!!! Thank you boss!!!

Thanks for watching!

Awesome job Andy! Would never have know it was your first technical video. Great introduction to what is going to be covered, all the visuals were clear (I would maybe recommend a bigger font on the topology), no speaking issues and unwanted "um". Thanks for the content, I had not seen this in action. Heard the name but now I know what it does!

[@permitipandyandy]

Thanks for watching and for the feedback! Will work on a larger font for the next one :)

Great video, Andy! Straightforward and informational. Keep it up!

Thanks for watching Jeff!

First of all your channel name just awesome...... Great explanations

[@djdawso]

Nice work, Andy! A few nice aspects of Netflow compared to other options, such as ACL logging or Embedded Packet Capture are that it has a low performance impact, you don't have to customize it for the specific type of traffic you're looking for, and you can pretty safely leave it on all the time so you don't have to worry about submitting a troubleshooting change request in a production environment. If you can also manage to configure a robust Collector to export the flow data to that's even better, but even with that it's a pretty handy tool to have readily available when trouble tickets come it (which they always do).

Thanks for watching and for the additional info!

Wow. Netflow is badass. So is your setup dude!!!!!

[@krishellehardson-hurley8043]

Thanks so much, great video! Only issue was not being able to see the whole terminal where the video blocked it -- but wasn't terrible! Keep it up :)

[@permitipandyandy]

Sorry bout that! Still trying to figure this whole thing out.

[@AzharKhan-sn9vf]

Can you Pl tell which software you are using for labs?????

[@HongeraGideon]

Great Andy

nice thank you for sharing

[@Naesman1167]

Great video. On a network with a couple hundred nodes how do you query source and destination without the analyzer.. or do you simply use an analyzer?

[@KaushalBeladiya]

Great Video 👍

Thanks for watching!

[@hobononono3435]

Very Good.

[@Sajithkumar]

Great demo. Question enabling net flow on a production - should we use ACL ? will it have similar impact as debug ip any any ?

[@permitipandyandy]

You don’t need an ACL for netflow and to my knowledge, most modern platforms can run it 24x7 with no negative impact on performance.

Thant a great
