Operation Manual – Port Basic ConfigurationH3C S3600 Series Ethernet Switches-Release 1510 Chapter 1 Port Basic Configuration1-51.2.2 Limiting Traffic on individual PortsBy performing the following configurations, you can limit different types of incomingtraffic on individual ports. When a type of incoming traffic exceeds the threshold you set,the system drops the packets exceeding the traffic limit to reduce the traffic ratio of thistype to the reasonable range, so as to keep normal network service.Table 1-4 Limit traffic on portOperation Command RemarksEnter system view system-view —Limit broadcast trafficreceived on each portbroadcast-suppression{ ratio | pps max-pps }OptionalBy default, the switchdoes not suppressbroadcast traffic.Enter Ethernet port view interface interface-typeinterface-number —Limit broadcast trafficreceived on the currentportbroadcast-suppression{ ratio | pps max-pps }OptionalBy default, the switchdoes not suppressbroadcast traffic.Limit multicast trafficreceived on the currentportmulticast-suppression{ ratio | pps max-pps }OptionalBy default, the switchdoes not suppressmulticast traffic.Limit unknown unicasttraffic received on thecurrent portunicast-suppression{ ratio | pps max-pps }OptionalBy default, the switchdoes not suppressunknown unicast traffic.1.2.3 Enabling Flow Control on a PortFlow control is enabled on both the local and peer switches. If congestion occurs on thelocal switch:z The local switch sends a message to notify the peer switch of stopping sendingpackets to itself or reducing the sending rate temporarily.z The peer switch will stop sending packets to the local switch or reduce the sendingrate temporarily when it receives the message; and vice versa. By this way, packetloss is avoided and the network service operates normally.
