7.5 Storm Control
This section shows you the storm control feature.
Storm control limits the number of broadcast, multicast and unicast packets the Switch receives per
second on the ports. When the maximum number of allowable broadcast, multicast and/or unicast
packets is reached per second, the subsequent packets are discarded. Enabling this feature reduces
broadcast, multicast and/or unicast packets in your network. You can specify limits for each packet
type on each port.
