Solved: WLC Netflow

hs08 · ‎07-23-2024

Hello,

I have WLC 2504 and AP in Flexconnect mode, then i enabled netflow on the WLC and after some hours i can't see any netflow traffic.

Can i know i can't see any netflow traffic due the AP is in flexconnect mode?

Restrictions for Using Netflow

The enhanced template is supported only on Cisco 3504, 5520, and 8540 controllers.
NetFlow is not supported on Cisco Virtual Wireless Controller (vWLC).
FlexConnect mode is not supported.

So 2504 is supported (on old template) but FlexConnect is not supported.

Hello,

That document is official from cisco?

Rich R · ‎07-23-2024

That document does not mention 2504 because 2504 and AireOS 8.5 are End of Support
