79.40 Storm Control
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.
