3850-X Wireless Controller Error

I am staging 2 3850X switches in a stack and trying to utilize the wireless controller functionality. When editing a WLAN and attempting to change the Interface/Interface Group I am getting the following error:

"Failed to Set.

Possible error could be with creating flow monitor. Pease check whether the flow record to enable Application Visibility is configured"

I have created a vlan for wireless clients on the switch and am trying to set that as the interface for this new WLAN. I can set it via CLI no problem but if I do that then anytime I try to modify anything in the GUI for this WLAN afterwards I get the above error. Any help would be much appreciated.

Hi Dan,

Under WLAN -> AVC section did you tick AVC ? If you are not using it untick that & see. (Flow records only used for when configuring AVC)

Below gives some config examples of 3850 WLAN, which may be useful to you

The interface/interface group

The interface/interface group that I was trying to set the WLAN to had a space in it.  I renamed my vlan to a one word vlan name and the error went away.

I had this problem a 2nd time

I had this problem a 2nd time and my pre-shared key has double-quotes around it "".  Once they were removed, I no longer got the error.

3850-X Wireless Controller Error

3850 gui is not solid may take couple of releases to reach there.

3850-X Wireless Controller Error

Rasika -

AVC is not ticked. I have also tried enabling that and disabling that with no luck. Thank you for the links, I actually used those as a guide as I was setting up these switches. I am thinking I will just use CLI to configure my WLAN for the moment but if anyone else has run into this problem feel free to add advice to this thread.
