Congestion Control Commands
The switch can set the maximum upload or download data transfer rate for any
port. It can control traffic storms by setting a maximum threshold for broadcast
traffic or multicast traffic. It can also set bounding thresholds for broadcast and
multicast storms which can be used to automatically trigger rate limits or to shut
down a port.
Rate Limit Commands
Rate limit commands allow 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 network.
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.
