18.6 Storm Control
Broadcast storm control limits the number of broadcast, multicast and destination lookup failure
(DLF) packets the Switch receives per second on the ports. When the maximum number of
allowable broadcast, multicast and/or DLF packets is reached per second, the subsequent packets
are discarded. Enable this feature to reduce broadcast, multicast and/or DLF packets in your
network. You can specify limits for each packet type on each port.
