4.4.5 Rate Limit
This function allows the network manager to control the maximum rate for traffic received on a port or transmitted from a port.
Rate limiting is configured on ports at the edge of a network to limit traffic coming in and out of the network. Packets that exceed
the acceptable amount of traffic are dropped.
Rate limiting can be applied to individual ports. When an interface is configured with this feature, the traffic rate will be monitored
by the hardware to verify conformity. Non-conforming traffic is dropped, conforming traffic is forwarded without any changes.
