4.3 Rate Limiter

To ensure reliable data exchange during heavy traffic, the device can limit the
traffic.
Entering a limit rate for each port specifies the amount of traffic the device is
permitted to transmit and receive.
If the data load transmitted at this port exceeds the maximum load entered,
the device will discard the excess data at this port.
A global setting enables/disables the rate limiter function at all ports.
