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.

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
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.
