1-6z This function is available for auto-negotiation-capable Gigabit Layer-2 Ethernet electrical portsonly..z If you repeatedly use the speed and the speed auto commands to configure the transmissionrate on a port, only the latest configuration takes effect.Configuring Storm SuppressionYou can use the following commands to suppress the broadcast, multicast, and unknown unicast traffic.In interface configuration mode, the suppression ratio indicates the maximum broadcast, multicast orunknown unicast traffic that is allowed to pass through an interface. When the broadcast, multicast, orunknown unicast traffic over the interface exceeds the threshold, the system will discard the extrapackets so that the broadcast, multicast or unknown unicast traffic ratio can drop below the limit toensure that the network functions properly.The storm suppression ratio settings configured for an Ethernet interface may get invalid if you enablethe storm constrain for the interface. For information about the storm constrain function, seeConfiguring the Storm Constrain Function on an Ethernet Interface.Follow these steps to set storm suppression ratios for one or multiple Ethernet interfaces:To do… Use the command… RemarksEnter system view system-view —EnterEthernetinterfaceviewinterface interface-typeinterface-numberEnterEthernetinterfaceview or portgroup view Enter portgroup viewport-group manualport-group-nameUse either command.If configured in Ethernet interfaceview, this feature takes effect on thecurrent port only; if configured in portgroup view, this feature takes effect onall ports in the port group.Set the broadcast stormsuppression ratiobroadcast-suppression{ ratio | pps max-pps }OptionalBy default, all broadcast traffic isallowed to pass through an interface,that is, broadcast traffic is notsuppressed.Set the multicast stormsuppression ratiomulticast-suppression{ ratio | pps max-pps }OptionalBy default, all multicast traffic isallowed to pass through an interface,that is, multicast traffic is notsuppressed.
