5 Traffic Suppression Configuration

5.1 Introduction to Traffic Suppression

This section describes the principle of traffic suppression.
Broadcast packets entering the S9300 are forwarded on all the interfaces in a VLAN, and
multicast packets are also forwarded on interfaces of the multicast group. After unknown unicast
packets enter the S9300, the S9300 broadcast the packets to all the interfaces. These three types
of packets consume great bandwidth, reduces available bandwidth of the system, and affects
normal forwarding and processing capabilities.
The traffic suppression function can be used to limit the traffic entering the interface, and to
protect the S9300 against the three types of traffic. It also guarantees available bandwidth and
processing capabilities of the S9300 when the traffic is abnormal.

5.2 Traffic Suppression Features Supported by the S9300

This section describes the traffic suppression features supported by the S9300.
The traffic suppression function can be configured on Ethernet interfaces of the S9300 .

5.3 Configuring Traffic Suppression

This section describes how to configure traffic suppression on a specified interface.

5.3.3 Checking the Configuration
5.3.1 Establishing the Configuration Task
Applicable Environment
To limit the rate of incoming broadcast, multicast, and unknown unicast packets on an interface
and protect the device against traffic attacks, you can configure traffic suppression on the
interface.
Pre-configuration Tasks
None
Data Preparation
