4.4.3 Port Broadcast 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.
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 is enabled by default.
• The default threshold is 1000K packets per second.
• Broadcast control does not effect IP multicast traffic.
• The specified threshold applies to each individual port on the Managed Switch.
