11.3 DoS Defend

DoS (Denial of Service) Attack is to occupy the network bandwidth maliciously by the network
attackers or the evil programs sending a lot of service requests to the Host, which incurs an
abnormal service or even breakdown of the network.
With DoS Defend function enabled, the switch can analyze the specific fields of the IP packets and
distinguish the malicious DoS attack packets. Upon detecting the packets, the switch will discard
the illegal packets directly and limit the transmission rate of the legal packets if the over legal
packets may incur a breakdown of the network. The switch can defend a few types of DoS attack
listed in the following table.
