3.3.3 Broadcast Storm Control (Global Setting)
Broadcast storms can 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 a complete halt.
You can protect your network from broadcast storms by setting a threshold for
broadcast traffic that applies to every port and then enabling broadcast storm control
on the required ports.
Any broadcast packets exceeding the specified threshold are dropped.
Note the following points about broadcast storm control:
■ Broadcast storm control is enabled by default.
■ Broadcast control does not affect IP multicast traffic.
When configuring broadcast storm control through the web interface or CLI, the
following parameter can be configured:
■ Broadcast Storm Threshold Level
11
– The threshold in packets per second. Specify
16, 64, 128, or 256 packets per second. The default is 256.
