Having just recently completed an audit of devices connected to APs that were not onboarded in Maestro, I think some sort of indication in the AP that a device is onboarded could be useful. The most common reason the device failed to onboard was a lack of DNS beting entered into the SM. From an audit standpoint, if I could log into an AP and see at a glance which SM is not Onboarded, it would greatly speed up the process. Some sort of indicator on the Session (PMP) or Monitor>Wireless (ePMP) page of the AP would be terrific. Green light = onboarded, red light = not onboarded.
