[Sysname] interface gigabitethernet 1/0/1 [Sysname-GigabitEthernet1/0/1] speed auto 10 1000 storm-constrain Syntax storm-constrain { broadcast | multicast | unicast } { pps | kbps | ratio } max-values min-values View undo storm-constrain { all | broadcast | multicast | unicast } Ethernet interface view Default level 2: System level Parameters all: Disables storm control for all types of packets: broadcast, multicast, and unknown unicast. broadcast: Enables or disables broadcast storm control. multicast: Enables or disables multicast storm control. unicast: Enables or disables unknown unicast storm control. pps: Sets storm control thresholds in pps. kbps: Sets storm control thresholds in kbps. ratio: Sets storm control thresholds as a percentage of the transmission capacity of the interface. max-values: Sets the upper threshold. min-values: Sets the lower threshold, ranging from 1 to max-values. Description Use storm-constrain to enable broadcast, multicast, or unknown unicast storm control on an Ethernet port. Use undo storm-constrain to disable storm control. By default, traffic storm control is disabled. To achieve desirable storm protection effect, avoid configuring both the storm-constrain command and any storm suppression command (unicast-suppression, multicast-suppression, and broadcast-suppression) on a port. An upper threshold must be greater than or equal to the corresponding lower threshold. HP does not recommend configuring the same value for the two thresholds. Examples # Enable unknown unicast storm control on GigabitEthernet 1/0/1, setting the upper and lower thresholds to 200 pps and 150 pps. system-view [Sysname] interface gigabitethernet 1/0/1 [Sysname-GigabitEthernet1/0/1] storm-constrain unicast pps 200 150 # Enable broadcast storm control on GigabitEthernet 1/0/2, setting the upper and lower thresholds to 2000 kbps and 1500 kbps. 33
