2.11.4 Storm Control
There is a unicast storm rate control, multicast storm rate control, and a broadcast storm rate control. These
only affect flooded frames, i.e. frames with a (VLAN ID, DMAC) pair not present on the MAC Address table.
The rate is 2^n, where n is equal to or less than 15, or "No Limit". The unit of the rate can be either pps
(packets per second) or kpps (kilo-packets per second). The configuration indicates the permitted packet rate
for unicast, multicast, or broadcast traffic across the switch.
Note: Frames, which are sent to the CPU of the switch are always limited to approximately 4 kpps. For
example, broadcasts in the management VLAN are limited to this rate. The management VLAN is configured
on the IP setup page.
