HCIE network engineers quickly complete equipment flow control and storm control

To ensure network security and prevent broadcast storms, limit the suppression of broadcast packet type traffic. Use appropriate storm control operations. The basic operation is as follows:

Configure broadcast traffic suppression on the interface and configure broadcast traffic suppression in the interface view. The maximum rate of broadcast packets is 100 kbit/s.

<HUAWEI> system-view

[~HUAWEI] interface G0/0/1

[~HUAWEI-10GE1/17/1] storm suppression broadcast cir 100

[*HUAWEI-10GE1/17/1] commit

Configure the interface broadcast storm control, and configure the broadcast storm control function in the interface view.

<HUAWEI> system-view

[~HUAWEI] interface G0/0/1

[~HUAWEI-10GE1/17/1] storm control broadcast min-rate 1000 max-rate 2000

//Configure the minimum threshold for storm control is 1000pps and the maximum threshold is 2000pps

[*HUAWEI-10GE1/17/1] storm control action error-down

//Configure the storm control action to close the interface

[*HUAWEI-10GE1/17/1] commit

Configure unknown unicast traffic suppression on the interface and configure unknown unicast traffic suppression in the view. The maximum rate of unknown unicast packets is 100 kbit/s.

<HUAWEI> system-view

[~HUAWEI] interface G0/0/1
