system-view [Sysname] interface ten-gigabitethernet 1/1/5 [Sysname-Ten-GigabitEthernet1/1/5] speed auto storm-constrain Use storm-constrain to enable broadcast, multicast, or unknown unicast storm control on an Ethernet port. Use undo storm-constrain to disable storm control. Syntax storm-constrain { broadcast | multicast | unicast } { pps | kbps | ratio } upperlimit lowerlimit undo storm-constrain { all | broadcast | multicast | unicast } Default Traffic storm control is disabled. Views Ethernet interface view Predefined user roles network-admin 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. upperlimit: Sets the upper threshold, in pps, kbps, or percentage. lowerlimit: Sets the lower threshold, in pps, kbps, or percentage. Usage guidelines After you configure this command, the device collects the statistics of a particular type of traffic at the specified interval, which can be configured by using the storm-constrain interval command. When a particular type of traffic exceeds its upper threshold, the interface takes a certain action, which can be configured by using the storm-constrain control command. Either of the storm-constrain, broadcast-suppression, multicast-suppression, and unicast-suppression commands can suppress storm on a port. The storm-constrain command uses software to suppress traffic, and affects the device performance to a certain extent. The broadcast-suppression, multicast-suppression, and unicast-suppression commands use the chip to physically suppress traffic, and have less influence on the device performance compared with the storm-constrain command. On the same type of traffic, do not configure the storm constrain command and either of the broadcast-suppression, multicast-suppression, and unicast-suppression commands on a port. Otherwise, the traffic suppression result is not determined. 28
