Differences between traffic suppression and storm control on S series switches

For S series switches, the differences between traffic suppression and storm control are as follows:
Traffic suppression aims at controlling traffic rates within an acceptable range to limit incoming and outgoing traffic on interfaces. If the rate of incoming broadcast, multicast, or unknown unicast packets on an interface exceeds the threshold, a switch discards the packets exceeding the threshold and only allows the packets within the threshold to pass through. Take traffic suppression of unknown unicast packets for example. Assume that the traffic suppression threshold of unknown unicast packets is 100 pps. That is, the switch allows only 100 packets to pass through within one second, and discards the excess packets. Within the next second, the switch also allows only 100 packets to pass through. If the rate of outgoing broadcast, multicast, or unknown unicast packets on an interface exceeds the threshold, the switch blocks all packets of this type. That is, the interface does not forward packets of this type.
Storm control aims at preventing broadcast storms. A switch with storm control configured only controls incoming traffic on interfaces. If the average rate of unknown unicast packets received by an interface of a switch within the storm control interval is higher than the specified upper threshold, the switch blocks packets on the interface or shuts down the interface according to the configured penalty action. If the interface has been blocked, when the rate of packets received by the interface falls below the lower threshold, the switch unblocks the interface. If the interface has been shut down, you need to run the undo shutdown command to enable the interface. Take storm control on unknown unicast packets for example. Assume that the upper threshold for storm control on unknown unicast packets is 100 pps, the lower threshold is 20 pps, and the storm control detection interval is 5 seconds. If the interface receives more than 500 (100 x 5) packets within 5 seconds, the switch shuts down the interface. The interface can receive packets only after its status recovers to Up. Alternatively, the switch blocks all unknown unicast packets on the interface until the 5 seconds expire. When the number of packets received by the interface falls below 100 (20 x 5), the switch allows the interface to receive unknown unicast packets.
For the incoming packets of the same type on an interface, only traffic suppression or storm control can be configured.
