WLC Multiple Netflow Exporter

WGL_BK — Sun, 05 Mar 2023 17:45:54 GMT

Hello everyone. We have a 5520 WLC running 8.10.183.0. A single Netflow exporter is set up currently, I'd like to add a second exporter to send the Netflow traffic from WLANs to another collector. The selector for a WLAN's exporter is a drop down list so I'm assuming that only one exporter can be set at the WLAN. Is there any way to configure this WLC to export Netflow to multiple collectors, much like on IOS/IOSXE?

- Chances are slim , check this document : https://www.plixer.com/blog/cisco-wlc-netflow-configuration/ and or try to use CLI instead because then usually a more direct error message is returned when a particular (extra) configuring of for instance a netflow exporter is not possible ,

Not that i am aware - still that is the limitation - there is a feature enhancement request when I looked some time back :

But since AirOS fading due to the New Cat 9800 controller there is not much interest to release I guess here.

Thank you - I did some reading and saw the plixer info as well as the bug. I also tried to configure it via CLI and I can't even add a second exporter as I thought. Error message, "Reached Max limit for Number of Flow Exporters.". Quite disappointing - now I'm wondering if i could send to a multicast group or something wacky to get the traffic to both. My collectors at the moment are Prime and Solarwinds - both have valid need for the data, I believe.

So AireOS is dead huh? After 15 years, Cisco Wireless AireOS Controllers are going away - Cisco Blogs That's too bad. Thank you.

- AireOS is not yet dead on the market , but the new controller from Cisco for wireless is the 9800 platform which all it's variants (including) virtual running IOS-XE ,
