Configuring DoS Defend Overview
1
Overview
The DoS (Denial of Service) defend feature provides protection against DoS attacks. DoS
attacks occupy the network bandwidth maliciously by sending numerous service requests
to the hosts. It results in an abnormal service or breakdown of the network.
With DoS Defend feature, the switch can analyze the specific fields of the IP packets,
distinguish the malicious DoS attack packets and discard them directly. Also, DoS Defend
feature can limit the transmission rate of legal packets. When the number of legal packets
exceeds the threshold value and may incur a breakdown of the network, the switch will
discard the packets.
