How to configure broadcast storm control on an interface of a CE series switch
Excessive broadcast packets on inbound and outbound interfaces of a switch will cause broadcast storms. To limit the rate of broadcast packets on an interface, you can configure broadcast storm control on the interface.
For example, you can configure broadcast storm control on 10GE1/0/1.
<HUAWEI> system-view
[~HUAWEI] interface 10ge 1/0/1
[~HUAWEI-10GE1/0/1] storm control broadcast min-rate 1000 max-rate 2000 //Set the lower threshold for storm control to 1000 pps and upper threshold to 2000 pps.
[*HUAWEI-10GE1/0/1] storm control action error-down //Configure the switch to shut down the interface when detecting a broadcast storm.

How to configure broadcast traffic suppression on an interface of a CE series switch
Excessive broadcast packets on inbound and outbound interfaces of a switch will cause broadcast storms. To limit the rate of broadcast packets on an interface, you can configure broadcast traffic suppression on the interface.
For example, you can configure broadcast traffic suppression on 10GE1/0/1 and set the maximum rate of broadcast packets on the interface to 100 kbit/s.
<HUAWEI> system-view
[~HUAWEI] interface 10ge 1/0/1
[~HUAWEI-10GE1/0/1] storm suppression broadcast cir 100
[*HUAWEI-10GE1/0/1] commit

How to configure unknown unicast traffic suppression on an interface of a CE series switch
Excessive unknown unicast packets on inbound and outbound interfaces of a switch will cause broadcast storms. To limit the rate of unknown unicast packets on an interface, you can configure unknown unicast traffic suppression on the interface.
For example, you can configure unknown unicast traffic suppression on 10GE1/0/1 and set the maximum rate of unknown unicast packets on 10GE1/0/1 to 100 kbit/s.
<HUAWEI> system-view
[~HUAWEI] interface 10ge 1/0/1
[~HUAWEI-10GE1/0/1] storm suppression unknown-unicast cir 100
[*HUAWEI-10GE1/0/1] commit
