What is NetFlow?

NetFlow is a protocol developed by Cisco to analyze network traffic. By capturing this information, network professionals can determine points of origin for network traffic, its destination, the volume of network traffic, and the paths on a network it takes.

By using NetFlow, network administrators can monitor networks, plan and anticipate network growth, and perform security analysis on networks. By capturing network data and converting that data to flows, NetFlow offers network admins a visual way to understand how their network is operating.

IT professionals can access NetFlow data in two ways. They can use a command-line interface (CLI) to view network traffic as a means for troubleshooting issues. They can also export data to a NetFlow collector, which will process the data for more complex analysis. There are both hardware and software collectors.
