system in
turn determines the state (authorized or unauthorized) of the controlled port
according to the instructions (accept or reject) received from the RADIUS server.
 802.1X Authentication Procedure
An 802.1X authentication can be initiated by supplicant system or authenticator system. When the
authenticator system detects an unauthenticated supplicant in LAN, it will initiate the 802.1X
authentication by sending EAP-Request/Identity packets to the supplicant. The supplicant system
can also launch an 802.1X client program to initiate an 802.1X authentication through the sending
of an EAPOL-Start packet to the switch,
This TP-LINK switch can authenticate supplicant systems in EAP relay mode or EAP terminating
mode. The following illustration of these two modes will take the 802.1X authentication procedure
initiated by the supplicant system for example.
（1） EAP Relay Mode
This mode is defined in 802.1X. In this mode, EAP-packets are encapsulated in higher level
protocol (such as EAPOR) packets to allow them successfully reach the authentication server.
This mode normally requires the RADIUS server to support the two fields of EAP: the
EAP-message field and the Message-authenticator field. This switch supports EAP-MD5
authentication way for the EAP relay mode. The following figure describes the basic EAP-MD5
authentication procedure.
Figure 11-19 EAP-MD5 Authentication Procedure
1. A supplicant system launches an 802.1X client program via its registered user name and
password to initiate an access request through the sending of an EAPOL-Start packet to the
switch. The 802.1X client program then forwards the packet to the switch to start the
authentication process.
2. Upon receiving the authentication request packet, the switch sends an EAP-Request/Identity
packet to ask the 802.1X client program for the user name.
