7.6 Strom control

7.6.1 Brief introduction of strom control

Restrict the speed rate of port receiving broadcast/multicast/ unknown unicast packets and

unknown unicast packets received by all ports by storm control configuration.

Strom control configuration

Use storm-control command in interface configuration mode to configure storm-control. Use

show interface command to display storm-control information.

 Configure storm control

storm-control { broadcast | multicast | unicast } target-rate

 Delete storm control

no storm-control { broadcast | multicast | unicast }

Configure it in global configuration mode:

 Configure unknown unicast storm control

storm-control unicast target-rate

 Delete unknown unicast storm control

no storm-control unicast

For example:

!Configure storm control of e0/1 with the speed rate being 64KBps

QTECH(config-if-ethernet-0/0/1)#storm-control broadcast 64

!Configure known multicast storm control of e0/3 with the speed rate

being 128KBps

QTECH(config)#storm-control unicast 128

Caution: global-based unknown unicast control cannot configured at the same time as port-

based unknown unicast control;the target rate of global-based unknown unicast control and

port-based broadcast control is 64KBps,but the target rate of port-based unknown unicast

control is 1KBps.
