12.1.2 Broadcast Storm Control Setup
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.
Click Rate > Storm Control in the navigation panel to display the screen as shown next.

Burst Size The burst size specifies the maximum amount of traffic that can be allowed out the port
at any one instance. In the “Token Bucket” algorithm this is referred to as the size of
the bucket as this value limits the number of tokens that can accumulate in the bucket.
