NetFlow Performance Analysis
Want to know the Netflow performance of your router and not sure where you can find that kind of information? Believe it or not it’s posted on CCO…The Cisco IOS® NetFlow feature set allows for the tracking of individual IP flows as they are received at a Cisco router or switching device. Network administrators can use the NetFlow flow records for a variety of purposes, including accounting, billing, network planning, traffic engineering, and user or application monitoring.
NetFlow services are available on Cisco IOS Software-based routers including Cisco 800 thru 7500 Series Routers, as well as the Cisco Catalyst® 6500 Series Switch, Cisco 7600, 10000, 12000 Series Routers and CRS-1 devices. For more details on NetFlow, refer to the “NetFlow Services Solutions Guide” white paper.
Although many Cisco customers want to deploy NetFlow services, they are naturally cautious about introducing new technology into their network without completely understanding the potential performance impact. Well look no further than this document that details the performance impact of enabling Netflow on your router:
