Storm control commands can be used to configure broadcast, multicast,
and unknown unicast storm control thresholds. Traffic 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
traffic on your network, performance can be severely degraded or
everything can come to 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.
storm-sample-type
The command toggles the threshold units for switchport packet-rate to be
either kilobits per second or packets per second.
