Introduction to NetFlow and NDE

NetFlow is a proprietary network protocol developed by Cisco Systems. NetFlow collects network traffic statistics by monitoring packets flowing through a given network device and storing the statistics in a NetFlow table on the device. NetFlow Data Export (NDE) converts the NetFlow table statistics into records formatted for export to data analysis tools, like NTA. NTA receives NetFlow data from NetFlow-enabled devices and generates graphical analyses of network traffic and resource use. This technical reference provides the procedures necessary to configure NetFlow and NDE for use with NTA.
