Storm-Control Commands
This section provides storm-
control configuration information. When incoming packets flood the LAN, it is
defined as a traffic storm condition leading to network performance degradation. Storm-Control features
prevents the occurance of such events.
To configure storm-control, enable the feature for all or specific interfaces. Once enabled the threshold
(storm-control level) can be set — this is the limit used to drop broadcast or unicast traffic. The Storm-
Control allows for the definition of rate limits of specific types of packets through the switch on a per-port,
per-type, basis.
Note:
The incoming packet size as well as the hard-coded packet size (512 bytes) is used to calculate
the actual rate of ingress traffic required to activate storm-control. As an example, if a configured limit is
assumed to be 10%, it can be converted to ~25000 pps. The arrived pps limit is set in the forwarding
