NetFlow/IPFIX data capabilities and required module?

NetFlow/IPFIX data capabilities and required module?

• A. NetFlow data is not supported by NPM.
• B. NPM can display and analyze NetFlow/IPFIX/sFlow data when used with the NetFlow Traffic Analyzer (NTA) module.
• C. NetFlow data is available natively without any module.
• D. NPM supports NetFlow only if Flow-based modules are installed, but not NTA.

Answer: (B)

NetFlow/IPFIX data are flow-based telemetry from routers and switches that show who is talking to whom, for how long, and how much traffic is exchanged. To view and analyze these flows in NPM, you need the NetFlow Traffic Analyzer module. NTA acts as the collector and analytics engine for NetFlow, IPFIX, and sFlow data, and once installed, NPM can present flow information in dashboards, reports, and top-talkers views alongside standard performance metrics. Without NTA, NetFlow data can’t be displayed in NPM, and merely having a generic flow-capable module isn’t enough—the NetFlow Traffic Analyzer module is the supported path for these data.
