9.5.2 Example for Configuring the Storm Control Function

Networking Requirements
As shown in
broadcast packets, the Switch forwards the packets to all the interfaces except the receiving
interface because the Switch cannot determine the outbound interface according to the
destination MAC address of packets. In this case, broadcast storms may occur on the network.
The forwarding performance of the Switch is thus reduced. The Switch is connected to the Layer
2 network and Layer 3 router. To perform storm control for broadcast packets, multicast packets,
or unknown unicast packets in a VLAN, you can configure storm control on GE 0/0/1.
