Traffic Prioritization
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 (kilopackets 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.
