The ''ipfix_mtu_limit'' parameter sets the maximum UDP packet size when sending IPFIX. By default, it equals the minimum MTU of the interfaces used for sending.

<note tip>
+
IPFIX/Netflow parameters can be changed without restarting fastDPI.\\
+
The configuration parameter ''ipfix_reserved'' allows reserving the necessary memory to enable/change IPFIX/Netflow parameters.\\
+
If IPFIX/Netflow parameters are set in the configuration file, memory reservation for IPFIX/Netflow is automatically enabled, and IPFIX/Netflow parameters and new exporter types can be changed without restarting fastDPI.

<note tip>For receiving, processing, and storing IPFIX, it is recommended to use the [[en:dpi:dpi_components:qoestor|QoE Store software for statistics collection]] and the [[en:dpi:dpi_components:dpiui|DPIUI2 Graphical Interface]].\\
