What role does the Aruba ClearPass Device Insight Analyzer play in the Device Insight architecture?

In the Aruba ClearPass Device Insight architecture, the Analyzer is the cloud-based component that performs advanced device classification. On-premises Collectors gather raw device metadata from various sources (e.g., SPAN, DHCP, SNMP) and securely forward it to the Analyzer. The Analyzer then applies machine learning (ML) algorithms, deep packet inspection (DPI) analysis, and supervised crowdsourcing techniques to this aggregated metadata. This process allows it to accurately classify a vast range of devices, including traditional IT, IoT, and OT endpoints, providing detailed visibility into what is on the network.

A. While the cloud component handles licensing, the Analyzer's primary role is advanced data analysis and classification, not just managing Collectors.
B. The on-premises Collector, not the cloud-based Analyzer, is the component that receives mirrored traffic from a SPAN port for analysis.
C. The on-premises Collector is responsible for performing active discovery scans using protocols like SNMP and Nmap to gather device information.

Page 2 states, "Metadata is then sent to the cloud-hosted ClearPass Device Insight analyzer for detailed analysis and classification... It leverages custom-built machine learning (ML) and crowdsourcing to discover and profile all connected devices."

3. Aruba Networks. (2021). ClearPass Device Insight 1.1 User Guide. Hewlett Packard Enterprise. Chapter 1, "Introduction," describes the architecture: "The Collector collects device data from your network and sends the data to the Analyzer. The Analyzer resides in the cloud and analyzes the data sent by the Collector."
