Description Use the storm-constrain interval command to set the interval for generating traffic statistics. Use the undo storm-constrain interval command to restore the default. By default, the interval for generating traffic statistics is 10 seconds. z The interval set by the storm-constrain interval command is specifically for the storm constrain function. It is different form that set by the flow-interval command. z For network stability consideration, configure the interval for generating traffic statistics to a value that is not shorter than the default. Examples # Set the interval for generating traffic statistics to 60 seconds. system-view [Sysname] storm-constrain interval 60 unicast-suppression Syntax unicast-suppression { ratio | pps max-pps } undo unicast-suppression View Layer 2 Ethernet interface view, port group view Default Level 2: System level Parameters ratio: Maximum percentage of unicast traffic to the total transmission capability of an Ethernet interface, in the range of 1 to 100. The smaller the ratio is, the less unicast traffic is allowed through the interface. pps max-pps: Specifies the maximum number of unknown unicast packets passing through an Ethernet interface per second. z For a 100-Mbps port, this value ranges from 1 to 148810 (in pps). z For a 1-Gbps port, this value ranges from 1 to 1488100 (in pps). z For a 10-Gbps port, this value ranges from 1 to 14881000 (in pps). Note that: z When a suppression granularity larger than 1 is specified on the device, the value of the pps keyword should be no smaller than and an integral multiple of the granularity. The broadcast suppression threshold value configured through this keyword on an Ethernet interface may not be 1-33
