Configuring Network Security Network Security
With the ARP Defend feature the switch can terminate receiving the ARP packets for 300 seconds
when the transmission speed of the legal ARP packet on the port exceeds the defined value so as
to avoid ARP flooding attack.
DoS Defend
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 the legal packets if the over legal packets may incur a breakdown of the
network.
802.1X
802.1X protocol is a protocol for port-based Network Access Control. It is used to authenticate
and control access from devices connected to the ports. If the device connected to the port is
authenticated by the authentication server successfully, its request to access the LAN will be
accepted; if not, its request will be denied.
802.1X authentication uses the typical client-server model which contains three device roles:
client/supplicant, authenticator and authentication server. This is described in the figure below:

Client
A client is a host, usually a computer, connected to a switch via a physical port. We recommend
that you install TP-LINK 802.1X authentication client software on the client hosts, enabling them
to request 802.1X authentication to access the LAN.
