This function allows the network manager to control the maximum rate for traffic
transmitted or received on an interface. Rate limiting is configured on interfaces at
the edge of a network to limit traffic into or out of the switch. Traffic that falls within
the rate limit is transmitted, while packets that exceed the acceptable amount of
traffic are dropped.
Rate limiting can be applied to individual ports or trunks. 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.
