Questions on the Netflow

NetFlow Generator is a free tool that works exclusively with NetFlow Analyzer. It passively captures raw network packets from devices that don’t support NetFlow, and translates them into NetFlow packets for NetFlow Analyzer to evaluate. This helps organizations avoid the costs of adding new networking devices.

NetFlow Generator is designed primarily for instances where the current networking device cannot generate NetFlow packets, and where the equipment is old and generates NetFlow but might utilize too much processing power after enabling it.

Step 1: Port mirroring is when a copy of all the raw data packets passing through a networking device is sent to a port within the same device (marked in green in the above representation) for inspection.

Step 2: NetFlow Generator then translates these mirrored data packets into readable NetFlow packets, and sends them to NetFlow Analyzer's listener port.

Step 3: NetFlow Analyzer later uses these packets to resolve readable bandwidth usage reports, network's traffic patterns, and more.
