Use
storm-constrain
to enable broadcast, multicast, or unknown unicast storm control on an
Ethernet port.
Use
undo storm-constrain
to disable storm control.

Parameters
all
: Disables storm control for all types of packets: broadcast, multicast, and unknown unicast.
broadcast
: Enables or disables broadcast storm control.
known-unicast
: Enables or disables unknown unicast storm control. This keyword is available in
Release 1121 and later.
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.
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
than the
storm-constrain
command.
