So far 5 versions of NetFlow have been released. Version 1 is the original version, while version 5 is the standard and most common NetFlow version deployed. Version 7 was released specifically for Catalyst 6500 and 7600 Series switches. It is similar to version 5, but does not include information on AS, interface, TCP flag, and TOS. NetFlow version 8 was introduced to reduce resource usage, and includes a choice of eleven aggregation schemes. Version 9, the most recent version, is a flexible, extensible format with support for MPLS, Multicast, and more. NetFlow Analyzer currently supports NetFlow versions 5, 7 and 9.
