About the Device Profile

The Device Profiler module produces a Device Profile, which is a hierarchical model consisting of three elements that are derived by the endpoint attributes—DeviceCategory, DeviceFamily, and DeviceName.

Table 1: Elements of a Device Profile

Endpoint Attributes

Description

DeviceCategory

Denotes the type of the device, for example, Computer, Smart Device, Printer, or Access Point.

DeviceFamily

Classifies devices based on the type of operating system or vendor. For example, when the category is Computer, ClearPass Policy Manager shows a device family of Windows, Linux, or macOS.

DeviceName

Denotes the name of the device. Devices in a family are organized based on characteristics such as their operating system version. For example, in a DeviceFamily of Windows, Policy Manager could show a DeviceName of Windows 8.1 or Windows Server 2019.

This hierarchical model provides a structured view of all endpoints accessing the network. In addition to these, a Device Profile also collects and stores the following:

IP address

Host name

Device vendor (via MACMedia Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network. OUIOrganizationally Unique Identifier.
