4.9.13 Storm Control Configuration
Storm control for the switch is configured on this page.
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

The configuration indicates the permitted packet rate for unicast, multicast or broadcast traffic across
the switch. The Storm Control Configuration screen in Figure 4-9-16 appears.
