Storm Control
A broadcast storm means that your network is overwhelmed with constant broadcast or
multicast traffic. Broadcast storms can eventually lead to a complete loss of network
connectivity as the packets proliferate.
Storm Control protects the Switch bandwidth from flooding packets, including broadcast
packets, multicast packets, and destination lookup failure (DLF).
Broadcast storm control limits the number of broadcast, multicast and unknown unicast (also
referred to as Destination Lookup Failure or DLF) packets the Switch receives per second on
the ports. When the maximum number of allowable broadcast, multicast and unknown unicast
packets is reached per second, the subsequent packets are discarded. Enable this feature to
reduce broadcast, multicast and unknown unicast packets in your network.
The default rate is 300pps for Broadcast and DLF. You can set to maximum rate of 5000pps for
multicast, broadcast or DLF.
