Setting Broadcast Storm Thresholds
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.
• The specified threshold applies to all ports on the switch.
Command Attributes
• Threshold – Threshold as percentage of port bandwidth.
(Range: 64-95232000; Default: 32000 octets per second)
• Protect Status – Shows whether or not broadcast storm control has been enabled.
(Default: Enabled)
Web – Click Port, Port/Trunk Broadcast Control. Set the threshold, mark the
Enabled field for the desired interface and click Apply.
