Broadcast Storm Control

15.1 Broadcast Storm Control Overview

This chapter introduces and shows you how to configure the broadcast storm control feature.

Broadcast storm control limits the number of broadcast, multicast and destination lookup failure
(DLF) packets the Switch receives per second on the ports. When the maximum number of
allowable broadcast, multicast and/or DLF packets is reached per second, the subsequent packets
are discarded. Enable this feature to reduce broadcast, multicast and/or DLF packets in your
network. You can specify limits for each packet type on each port.

15.1.1 What You Can Do

Use the

Broadcast Storm Control

screen (

Section 15.2 on page 144

) to limit the number of

broadcast, multicast and destination lookup failure (DLF) packets the Switch receives per second on
the ports.

15.2 Broadcast Storm Control Setup

Click

Advanced Application

>

Broadcast Storm Control

in the navigation panel to display the

screen as shown next.
