RTS/CTS handshake. Enter a value between 256 and 2346 to specify the value of the RTS

/CTS Threshold.

4. 802.1X: The 802.1X standard is designed to enhance the security of wireless local area

networks that follow the IEEE 802.11 standard. 802.1X uses an existing protocol, the

Extensible Authentication Protocol (EAP) for message exchange during the authentication

process.

In a wireless LAN with 802.1X, a user requests access to an access point (known as the

authenticator). The access point forces the user into an unauthorized state that allows the

client to send only an EAP-start message. The AP replies with an EAP-request identify

message to obtain the clients identity. The clients EAP-response packet containing the

clients identity is forwarded to the authentication server. The authentication server is

configured to authenticate clients with a specific authentication algorithm. The result is an

accept or reject packet from authentication server to AP. Once authenticated, the AP opens

the client’s port and traffic will be forwarded.
