Command Manual – Port Correlation ConfigurationH3C S7500E Series Ethernet SwitchesChapter 1 Ethernet Port ConfigurationCommands1-27Parametersall: Disables the storm constrain function for all types of packets (that is, multicastpackets, and broadcast packets).broadcast: Enables/Disables the storm constrain function for broadcast packets.multicast: Enables/Disables the storm constrain function for multicast packets.pps: Specifies the thresholds to be configured are measured in pps.max-pps-values: Upper threshold to be set, in pps, representing packets per second.The value range of max-pps varies with port types.min-pps-values: Lower threshold to be set, in the range 1 to max-pps-values (in pps).DescriptionUse the storm-constrain command to enable the storm constrain function for specifictype of packets and set the upper and lower thresholds.Use the undo storm-constrain command to disable the storm constrain function forspecific type of packets.By default, the storm constrain function is not enabled.Note:z Do not use the storm-constrain command along with the multicast-suppressioncommand, or the broadcast-suppression command. Otherwise, traffics may besuppressed in an unpredictable way.z An upper threshold cannot be less than the corresponding lower threshold. Besides,do not configure the two thresholds to the same value.Examples# Enable the storm constrain function for broadcast packets on Ethernet 2/0/1, settingthe upper and lower threshold to 200 pps and 150 pps. system-view[Sysname] interface ethernet 2/0/1[Sysname-Ethernet2/0/1] storm-constrain broadcast pps 200 1501.1.27 storm-constrain controlSyntaxstorm-constrain control { block | shutdown }undo storm-constrain control
