Broadcast storms may occur when a device on your network is malfunctioning, or if application programs are not well designed or properly configured. If there is too much broadcast traffic on your network, performance can be severely degraded or everything can come to complete halt.

You can protect your network from broadcast storms by setting a threshold for broadcast traffic. Any broadcast packets exceeding the specified threshold will then be dropped.

Command Usage

•Broadcast Storm Control is enabled by default.

•Broadcast control does not effect IP multicast traffic.

Command Attributes

•Port - Port number.

•Type – Indicates the port type. (100BASE-TX, 1000BASE-T, or SFP)

•Protect Status – Shows whether or not broadcast storm control has been enabled. (Default: Enabled)

•Threshold – Threshold as percentage of port bandwidth. (Options: 500-262143

packets per second; Default: 500 pps).

•Trunk – Shows if a port is a trunk member.
