NetFlow version 5, 8 and 9 support IPv4, only version 9 supports IPv6, the default transport used is UDP. Also, the NetFlow data can be configured to export the NetFlow data to a collection server if a server is deployed. It can even be used to configure IPFIX or packet sampling similar to sFlow. The benefit of this is that NetFlow monitoring is enabled by default in the tool – there is no add-on or upgrade required.
