Overview NetFlow is a Cisco IOS Software feature, designed to track, document and-optionally-accelerate the flow of IP packets as they traverse a network. NetFlow provides two key benefits to the end user. First, by tracking IP flows, NetFlow produces a detailed record of traffic flows on a network. This record can be used for a variety of purposes, including accounting, billing, network planning, traffic engineering, and user/application monitoring. Second, because NetFlow keeps a cache of active IP flows, it can be used in conjunction with Cisco Express Forwarding as a highly optimized routing cache, accelerating the flow of data as it passes from interface to interface. This paper examines how NetFlow is implemented on logical interfaces.
