How does Cisco ISE differentiate between different types of endpoints?

Cisco ISE differentiates between various types of endpoints primarily through profiling mechanisms. These mechanisms are designed to gather information about devices when they connect to the network, employing multiple techniques to identify and categorize endpoints accurately.

Profiling involves several sophisticated methods, such as analyzing DHCP, RADIUS, HTTP user agent strings, and other protocols. This data helps ISE to collect attributes like device type, operating system, manufacturer, and other capabilities. By leveraging this comprehensive profiling information, ISE can enforce appropriate access policies tailored to the specific type of device, which enhances security and network management.

The other choices are not effective methods for differentiating endpoint types in the ISE context. User feedback and configurations can influence how endpoints are managed but are not primary methods of identification. Analyzing network bandwidth usage might give insights into device behavior but does not aid in accurately defining what type of device is connected. Scanning device IP addresses alone would not provide enough detail to classify and profile devices effectively, as many devices can share an IP address or indicate the same network behavior without revealing their actual identity.
