Traffic Suppression
As shown in Figure 9-1,
- Traffic suppression can be configured in a VLAN on a Layer 2 network device to limit the rates of broadcast packets, multicast packets, and unknown unicast packets in the VLAN.
- Switch A is connected to a Layer 2 network and a router. To limit the rates of broadcast, multicast, and unknown unicast packets forwarded by the Layer 2 network, configure traffic suppression on the Layer 2 Ethernet interface 10GE1/0/1 of Switch A.
- You can also configure Switch A to block the outgoing broadcast, multicast, and unknown unicast packets on 10GE1/0/1 to ensure Layer 2 network security.
