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 at the
same time. Otherwise, the traffic suppression result is not determined.
When configuring this command, make sure upperlimit is greater than lowerlimit.
Examples
# Enable unknown unicast storm control on GigabitEthernet 1/0/1, setting the upper and lower
thresholds to 200 pps and 150 pps.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] storm-constrain unicast pps 200 150
# Enable broadcast storm control on GigabitEthernet 1/0/2, setting the upper and lower thresholds to
2000 kbps and 1500 kbps.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/2
[Sysname-GigabitEthernet1/0/2] storm-constrain broadcast kbps 2000 1500
# Enable multicast storm control on GigabitEthernet 1/0/3, setting the upper and lower thresholds to
80% and 15%.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/3
[Sysname-GigabitEthernet1/0/3] storm-constrain multicast ratio 80 15

storm-constrain control
Use storm-constrain control to set the protective action to take on an Ethernet interface when a
type of traffic (unknown unicast, multicast, or broadcast) exceeds the upper storm control threshold.
Use undo storm-constrain control to restore the default.
Syntax
storm-constrain control { block | shutdown }
undo storm-constrain control
Default
No action is taken on an Ethernet interface when a type of traffic exceeds the upper storm control
threshold.

Parameters
block: Blocks this type of traffic, while forwarding other types of traffic. Even though the interface
does not forward the blocked traffic, it still counts the traffic. When the blocked traffic is detected
dropping below the lower threshold, the port begins to forward the traffic.
shutdown: Shuts down automatically. The interface shuts down automatically and stops forwarding
any traffic. When the blocked traffic is detected dropping below the lower threshold, the port does not
