Overview

The storm control feature allows you to control unknown-unicast and broadcast traffic on Layer 2, Layer 3,

and multicast physical interfaces.

Configuring Storm Control

Storm control is supported in INTERFACE mode and CONFIGURATION mode

Configuring storm control from INTERFACE mode

Configure storm control from INTERFACE mode using the command storm control. From INTERFACE

mode:

• You can only on configure storm control for ingress traffic.

• If you configure storm control from both INTERFACE and CONFIGURATION mode, the

INTERFACE mode configurations override the CONFIGURATION mode configurations.

• The percentage of storm control is calculated based on the advertised rate of the port, not by the speed

setting.

Configuring storm control from CONFIGURATION mode

Configure storm control from CONFIGURATION mode using the command storm control. From

CONFIGURATION mode you can configure storm control for ingress and egress traffic.

FTOS Behavior: The FTOS operating software supports broadcast control (storm-control broadcast

command) for Layer 2 and Layer 3 traffic.

FTOS Behavior: The minimum number of packets per second (PPS) that storm control can limit is

two.
