Hello,
If multiple controller address are send by DNS while controller discovery, if the first address correspond of a controller with lower (not supported) version does the AP try to join the next addresses in the DNS list ?
In the opposite case : if the first address met correspond of a higher (not supported) version, does it try the next addresses ?
Regards

"When using DNS, AP learns multiple IP addresses to associate with a controller. If the primary controller is unavailable or does not respond, the AP continues through the list of learned IP addresses until it establishes a connection with an available controller. This takes approximately 3.5 minutes per controller."
