32Default level2: System levelParametersNoneDescriptionUse the storm-constrain enable trap command to enable an Ethernet interface to send storm controlthreshold event traps. Triggering events include traffic exceeding the upper threshold and traffic fallingbelow the lower threshold from the upper threshold.Use the undo storm-constrain enable trap command to disable trap message sending.By default, a storm control-enabled interface sends out traps when monitored traffic exceeds the upperthreshold or falls below the lower threshold from the upper threshold.Examples# Disable interface GigabitEthernet 1/0/1 from sending out storm control threshold event traps. system-view[Sysname] interface gigabitEthernet 1/0/1[Sysname-GigabitEthernet1/0/1] undo storm-constrain enable trapstorm-constrain intervalSyntaxstorm-constrain interval secondsundo storm-constrain intervalViewSystem viewDefault level2: System levelParametersseconds: Traffic polling interval (in seconds) of the storm control module. The value range is 1 to 300.DescriptionUse the storm-constrain interval command to set the traffic polling interval of the storm control module.Use the undo storm-constrain interval command to restore the default.By default, the storm control module polls traffic statistics every 10 seconds.For network stability, use the default or a higher polling interval.NOTE:The interval set by the storm-constrain interval command is specific to storm control. To set the statisticspolling interval of an interface, use the flow-interval command.Examples# Set the traffic statistics polling interval of the storm control module to 60 seconds. system-view
