A company has HPE Aruba Networking infrastructure devices. The devices authenticate clients to HPE Aruba Networking ClearPass Policy Manager (CPPM). You want CPPM to track information about clients, such as their IP addresses and their network bandwidth utilization.
What should you set up on the network infrastructure devices to help that happen?
A. Logging with CPPM configured as a Syslog server.
B. Dynamic authorization enabled in the RADIUS settings for CPP
C. RADIUS accounting to CPPM, including interim updates.
D. An IF-MAP interface with CPPM as the destination.
Explanation:
RADIUS Accounting:
RADIUS accounting enables network devices to report client session details (e.g., IP addresses, session duration, bandwidth usage) to CPPM.
Interim updates ensure CPPM receives ongoing updates about the client’s session, enabling accurate tracking.
Option Analysis:
Option A: Incorrect. Syslog logging sends general system logs, not client session details.
Option B: Incorrect. Dynamic authorization (CoA) handles session changes but does not provide usage tracking.
Option C: Correct. RADIUS accounting with interim updates tracks client IP addresses and bandwidth utilization.
Option D: Incorrect. IF-MAP interfaces are used for metadata sharing, not for RADIUS-based tracking.
