Storm-Constrain - HP 5900 series Command Reference Manual

Usage guidelines
10-GE interfaces support only 1000, 10000, and auto keywords of the command.
40-GE interfaces support only the 40000 and auto keywords of the command.
For a fiber port, use the speed command to set its speed to match the rate of a transceiver module.
Examples
# Configure Ten-GigabitEthernet 1/0/1 to autonegotiate the speed.

[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] 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.
