Device fingerprinting allows collection of various attributes about a device connecting to your network. The collected attributes can fully or partially identify individual devices, including the client’s OS, device type, and browser being used.
Device Fingerprinting can provide more information for the station and allows system administrators to be more aware of the types of devices in use and take necessary actions. You can view the details of the devices via Monitor > Dashboard. You can import, export, add, delete, or restore the devices using the fingerprint command and the show fingerprints command displays the device fingerprints stored in the system. See Command Reference Guide for more information on the CLI commands.
