With this release, NetFlow can export data in NetFlow v9 (version 9) export format. This format is flexible and extensible, which provides the versatility needed to support new fields and record types. This format accommodates new NetFlow-supported technologies such as Multicast, MPLS, NAT, and BGP next hop. Third-party business partners who produce applications that provide NetFlow Collection Engine (formerly called NetFlow FlowCollector) or display services for NetFlow do not need to recompile their applications each time a new NetFlow technology is added. Instead, with the NetFlow v9 Export Format feature, they can use an external data file that documents the known template formats and field types. NetFlow version 9 data export supports CEF switching, dCEF switching, and fast switching
