Broadcast Storm Control | Accton Technology 24/48-Port, ES4548D

Chapter 18: Broadcast Storm Control

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.

Setting Broadcast Storm Thresholds

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

Command Usage

•Broadcast control does not effect IP multicast traffic.

•The resolution is 1 packet per second (pps); i.e., any setting between 500-262143 is acceptable.

Command Attributes

•Port1 – Port number.

•Trunk2 – Trunk number

•Type – Indicates the port type. (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)

•Trunk1 – Shows if port is a trunk member.

Web – Click Port, Port Broadcast Control or Trunk Broadcast Control. Check the Enabled box for any interface, set the threshold, and click Apply.
