A customer has an AOS 10 architecture, consisting of Aruba AP and AOS-CX switches, managed by Aruba Central. The customer wants to obtain information…

Aruba Central automatically performs client profiling by analyzing telemetry data received from managed Aruba devices, such as Access Points and AOS-CX switches. This feature, known as Client Insights, uses data gathered from network traffic (e.g., DHCP options, MAC OUI, HTTP User-Agent strings) to classify clients by operating system, hardware vendor, and device category. This process is integral to the platform and does not require additional hardware like gateways or complex network reconfigurations like setting up IP helpers.

A: Aruba Gateways can enhance profiling with Deep Packet Inspection (DPI), but they are not a prerequisite for obtaining basic information like OS and device category from APs and switches.

B: Aruba Central is a cloud management platform, not a DHCP server or relay. Configuring it as an IP helper is technically incorrect and not a valid method for client profiling.

D: VSX is a high-availability and redundancy technology for switches. It is not a mechanism designed for packet sniffing or forwarding telemetry to Aruba Central for analysis.

1. Aruba Central User Guide: In the section on Monitoring

the "Clients" and "Client Insights" features are described. It states

"Client Insights classifies the clients and displays information about the client category

family

and profile... Client classification is done by analyzing the data from Aruba APs and Switches." This confirms that telemetry from existing devices is the source. (Refer to Aruba Central documentation

Monitoring > Client Insights section).

2. Aruba Client Insights Solution Overview: This document details the profiling mechanism

stating

"Client Insights leverages telemetry from Aruba APs

switches

and gateways... to discover and profile all connected clients." This shows that APs and switches are primary sources

with gateways being an optional

enhancing component. (Refer to Aruba document number SOClientInsights.pdf).

3. ArubaOS 10 Fundamentals Guide: The guide explains the architecture where APs and switches establish secure tunnels to Aruba Central to forward management traffic and telemetry data. This telemetry is the foundation for Central's AIOps and monitoring capabilities

including client profiling. (Refer to ArubaOS 10 Fundamentals Guide

Chapter on "Aruba Central Management").
