Broadcast Storm Control

14.1 Overview

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

14.2 Broadcast Storm Control Setup

Broadcast storm control limits the number of broadcast, multicast and destination lookup failure (DLF) frames the MES-2110 receives per second on the ports. When the maximum number of allowable broadcast, multicast and/or DLF frames is reached per second, the subsequent frames are discarded. Enable this feature to reduce broadcast, multicast and/or DLF frames in your network. You can specify limits for each frame type on each port.

Click Configuration > Storm Control in the navigation panel to display the screen as shown next.
