Yes I have those enabled.
We wanted to be able to auto-fill the mac address of the device that is connected and is being registered in the guest device repository.
The user connects to SSID_A and if device does not exist, they are given captive portal role in controller forcing them to go to operator login page. They log in and they have to register their device name and mac address. This all works fine, but we wanted to simplify finding the mac address of the device, either by running some type of script or something that would either auto-fill it in that field or display it as part of the form.
