Configuration Guide - Security
Networking Requirements
As shown in
limit the number of broadcast, multicast, or unknown unicast packets forwarded on the Layer 2
network, you can configure traffic suppression on GE 1/0/2.

Procedure
Step 1 Enter the interface view.
<Quidway> system-view
[Quidway] interface gigabitethernet 1/0/2
Step 2 Configure traffic suppression for broadcast packets.
[Quidway-GigabitEthernet1/0/2] broadcast-suppression cir 100
Step 3 Configure traffic suppression for multicast packets.
[Quidway-GigabitEthernet1/0/2] multicast-suppression 80
Step 4 Configure traffic suppression for unknown unicast packets.
[Quidway-GigabitEthernet1/0/2] unicast-suppression cir 100
Step 5 Verify the configuration.
Run the display flow-suppression interface command, and you can view the configuration of
traffic suppression on GE 1/0/2.
