7-5 Storm Control
The section allows user to configure the Storm control for the switch. There is a destination
lookup failure 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 configuration indicates the permitted packet rate for unicast,
multicast or broadcast traffic across the switch.

2. Click the port to be enabled, and configure the Rate limit condition.
4. Click the Apply button to save the setting.
5. To cancel the setting, click the Reset button to revert to previously saved values.
