Implement NetFlow IOS-XE with NBAR Discovery
I’m pretty sure that there are many examples out there to create NetFlow configuration and very well documented as well, however, I wanted to give my config a crack and also wanted to share. I’m adding one more bit of information as it is very useful to keep your network on-check, and that is the NBAR addition. Which Direction for NetFlow? I have read somewhere, and I refuse to look for the document again, thinking it was from Lancope’s website, but I remember reading that NetFlow works better if applied in only one direction. Pretty sure that many people out there will have their opinions and reasons to do it in very different directions on the same interface, but after lots of thinking, it made sense to me.
