You can configure limits on broadcast, multicast and unknown unicast traffic to
control traffic storms which may occur when a network device is malfunctioning,
the network is not properly configured, or application programs are not well
designed or properly configured. Traffic storms caused by any of these problems
can severely degrade performance or bring your network to a complete halt.
You can protect your network from traffic storms by setting a threshold for
broadcast, multicast, or unknown unicast traffic. Any packets exceeding the
specified threshold will then be dropped. Note that the limit specified on this page
applies to each port
