I am very much interested in understanding how Aruba's Device Fingerprinting functionality actually works. Is a device identified by MAC, OUI, something else ?
Would be very much interested in an in-depth technical explanation if there's a doc available anywhere.

The documentation , as I read it, is very 'light'.
I understand that there is a new knob in the AAA Profile to get the controller to perform Device Identification.
However, I can not find any documentation to say how you can control what is done with this information. Specifcally,
1) How do you define that a device type is Non Corporate/Personal, and thus should have its role changed?
2) How can you define the role a device , that has identified as Non Corporate/Personal, would be moved to?
3) What mechanism/s are available to change the role of a Non Corporate/Personal device? RADIUS? User Derivation rule? Server Derivation Rule? XML API?
Would someone please point me to the documentation if it exists, or otherwise please fill in the gaps.

Elsewhere in this forum this feature is also referred to as DHCP Fingerprinting.
This post gives all the details of how to configure it:
COTD: DHCP Fingerprinting how-to (ArubaOS 220.127.116.11 and above)
Apparently, the 'Device Type Classification' option on the AAA profile merely advises the administrator of the OS of the device based upon the User Agent in the browser. Currently there is no way to act on this information via configuration.
