Versions 22.214.171.124 on controllers (4 WISMs) and 126.96.36.199 on WCS.
Created a test WLAN which was used for a week or so, WPA2/PSK, broadcast ssid, standard stuff. I no longer wish to use it and set the enabled state in the template to disable and then saved and applied the template to the controllers. On various devices, I can still see it broadcasting! I have even checked on the individual controllers and the WLAN is set disabled, so no WCS sync issue. I also tried switching the broadcast ssid to off and reapplying it and this makes no difference.
If I try to connect to the WLAN, this fails, which is obviously a good thing! I have not tried to delete it yet as there are situations where we need the ability to enable/disable wlans.
Anybody else seen this issue before I report it to TAC?
