4.4.4 Storm Control
Storm control for the switch is configured on this page. There are a broadcast storm rate control, multicast storm rate control,
and unicast 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 configuration indicates the permitted packet rate for unicast, multicast or broadcast traffic across the switch as the Storm
Control configuration screen in Figure 4-60 appears.
