You would set this in the additional settings of the network policy. You can also do this on the CLI of the AP, but you'd have to create a supplemental CLI object to make sure this command did not get erased when the AP reboots. If you can tell me which HiveManager platform you are using, I can give you more detailed instructions on where to find the DNS setting in the HiveManager. The HiveManager platform options are: HiveManager Classic (myhive.aerohive.com) or HiveManager (formerly NG, cloud.aerohive.com)
