When a type of incomingtraffic exceeds the threshold you set, the system drops the packets exceeding the trafficlimit to reduce the traffic ratio of this type to the reasonable range, so as to keep normalnetwork service.Table 1-2 Limit traffic on portOperation Command RemarksEnter system view system-view —Limit broadcast trafficreceived on each portbroadcast-suppressionratioOptionalBy default, the switchdoes not suppressbroadcast traffic.Enter Ethernet port view interface interface-typeinterface-number —Limit broadcast trafficreceived on the currentportbroadcast-suppression{ ratio | bps max-bps }OptionalBy default, the switchdoes not suppressbroadcast traffic.
