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.

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

.
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.
