Device Operation

802.1x is a server-based port authentication which restricts unauthorized (rogue) clients from connecting to a Local

Area Network. In its simplest form, 802.1x usually involves three parties: supplicant (client device), authenticator

(Ethernet switch or WAP), and an authentication server. Before the device is permitted on the network, port

communication is restricted to Extensible Authentication Protocol over LAN (EAPOL) trac. If the device passes the

authentication process, the authentication server noties the switch, allowing the client to access the LAN.

The illustration below shows the basic architecture.

Protocol Description

PEAP/MSCHAPv2

Protected EAP; uses basic credentials in addition to a CA (certicate authority) certicate.

EAP-TLS

EAP Transport Layer Security; uses a client certicate, private key, private key password,

and CA (certicate authority) certicate.

IMPORTANT: If an 802.1x-enabled AT-USB-EX350-KIT is connected to a network without

an active or operational authentication server, then the AT-USB-EX350-KIT will not function

correctly until the expected message is returned from a RADIUS server. If it is unclear as to

whether the network uses 802.1x authentication, consult the IT administrator for assistance.
