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
