Device Fingerprints Dictionary

Device fingerprints are composed of information collected about a network device in order to uniquely identify the device on subsequent sessions. A device fingerprint can fully or partially identify individual users or devices even when cookies and other tracking data are turned off. The Device Fingerprints page shows a listing of all the device fingerprints recognized by the Profile module. These fingerprints are updated from the Aruba Policy Manager Updates Portal (see Software Updates for more information). Custom device fingerprints can be added and updated between Policy Manager servers.

If custom device fingerprints are configured, the custom rules are evaluated before the default rules are evaluated.
