The problem is that the controller is not sending information on APs whose mac address ends in FE or FF when being polled via SNMP. The AP works fine on the controller, but Airwave does not receive information on that AP from the controller when it polls it via SNMP.
The bug is in the controller code and has been fixed in later version of Aruba OS,
The AP will work just fine, it is just that Airwave does not receive information about the AP via SNMP when polling the controller. With that being said, there is nothing wrong with the AP or Airwave
