Running periodic subnet scans on devices from HPE Aruba Networking ClearPass Policy Manager (CPPM) can be used to gather DHCP fingerprints, which help determine a client's device category and operating system. DHCP fingerprints are unique patterns in DHCP request packets that provide valuable information about the device type and OS, assisting in device profiling and policy enforcement.
1.DHCP Fingerprinting: This technique captures specific details from DHCP packets to identify the type and operating system of a device.
2.Device Profiling: By running subnet scans, CPPM can continuously update its device database with accurate profiles, ensuring that policies are applied correctly based on the device type.
3.Network Visibility: Regular scanning helps maintain up-to-date visibility of all devices on the network, improving security and management.
