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.
