Solved: Re: Which Wireless LAN Controller Software version supports 802.1AX ?

Support Cat · ‎12-06-2019

I have a AIR-CT8540-K9 running version 8.2.167.6 which doesn't have 802.1AX. The recommend version is 8.5.151.0 Can anyone tell me if this has 802.1AX? I know 8540 Wireless Controller does have 802.1AX but I can't find out when it was added.

Yeah it’s not the controller code, it’s the AP’s that need to support ax then you have to verify what controller code supports that model access point.
