Cisco invented NetFlow and is the leader in IP traffic flow technology. Learn how it works, NetFlow v5/v9 vs IPFIX/sFlow, and use cases. We’ll also dive into the technical details of how the Netflow protocol works, including the Netflow ports, and the various Netflow versions. NetFlow collects and exports IP flow metadata (not packet payloads) from network devices. 6 days ago · Learn how Network Flow Analysis uses NetFlow, sFlow, and IPFIX to reveal traffic patterns, spot anomalies, and improve network visibility at scale. 4 days ago · This article will cover the basics of Netflow, including its use cases, Netflow supported devices, Netflow history, and variants. . NetFlow NetFlow is a feature that was introduced on Cisco routers around 1996 that provides the ability to collect IP network traffic as it enters or exits an interface. By analyzing NetFlow data, you can get a picture of network traffic flow and volume. NetFlow provides valuable information about network users and applications, peak usage times, and traffic routing. NetFlow NetFlow is a feature that was introduced on Cisco routers around 1996 that provides the ability to collect IP network traffic as it enters or exits an interface. By analyzing the data provided by NetFlow, a network administrator can determine things such as the source and destination traffic, class of service, and the causes of congestion. NetFlow is a network protocol widely used to collect metadata about the IP traffic flowing across network devices such as routers, switches and hosts. What is NetFlow? NetFlow is a network protocol developed by Cisco for collecting IP traffic information and monitoring network flow. Oct 18, 2024 · NetFlow is a network monitoring protocol, developed by Cisco, designed to capture measurements about the volume and types of traffic traversing a network device. Jul 21, 2025 · Netflow is a network protocol that collects & monitors network flow traffic, capturing important aspects such as IP addresses, protocol types, and port numbers. NetFlow, the most widely-used standard for flow data statistics, was developed by Cisco to monitor and record all traffic as it passes in to or out of an interface.
