Some types of traffic, such as video, can create a high rate of small UDP packets. When the packets per second rate becomes too high drops can occur. To optimize a port for UDP traffic use the command
system port advanced rx-udp-flow ENABLE port PORT
This option should be enabled for the physical port that the WAN being used is configured on.
Not all hardware platforms support this setting or may only support the setting on some ethernet ports. Contact Ecessa technical support for help determining if this option is appropriate to use and whether it is supported by the hardware being used.
