====== Accounting data export using the IPFIX format ======
{{indexmenu_n>4}}

Starting from the VAS Experts DPI version 8.0, accounting data along with the Radius protocol data can also be exported using the ipfix format.
Ipfix export is configured by the following parameters in fastpcrf.conf:
<code>
ipfix_dev=em1
ipfix_udp_collectors=1.2.3.4:1500,1.2.3.5:1501
ipfix_tcp_collectors=1.2.3.6:9418
</code>
here ''em1'' is the name of network interface used to export\\ 
''ipfix_udp_collectors'' are the udp collectors addresses\\ 
''ipfix_tcp_collectors'' are the tcp collectors addresses\\ 

Only "in use" collector addresses should be specified: for example, if only the UDP collector is supported then there is no need to specify the ''ipfix_tcp_collectors''.
