8.1 Introduction to Traffic Suppression

This section describes the principle of traffic suppression.
Broadcast packets, multicast packets and unknown unicast packets entering the S2700 are
forwarded on all the interfaces in a VLAN. 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 S2700 against the three types of traffic. It also guarantees available bandwidth and
processing capabilities of the S2700 when the traffic is abnormal.

8.2 Traffic Suppression Features Supported by the S2700

This section describes the traffic suppression features supported by the S2700.
The traffic suppression function can be configured on VLAN and Ethernet interfaces of the
S2700.
The S2700 can suppress the broadcast, multicast, and unicast traffic.

8.3 Configuring Traffic Suppression

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

8.3.1 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
To configure traffic suppression, you need the following data.
No.
