1. Framework for 802.1x devices
A 802.1x system consists of three parts: Supplicant System, Authenticator System, and
Authentication Server System. Please refer to following Figure
The supplicant carries to point of is the equipments that claim visit network, and generally is a
supplicant terminal system, such as the supplicant's PC machine, must install on the supplicant
terminal system a 802.1 x supplicants carry the software, that software to realize 802.1 x the
supplicant in the agreement carry the part. Supplicant System is a kind of device to ask to visit
internet, commonly as user end system, e.g. user's PC. 802.1x supplicant system must be
installed in user end system that complete the part of supplicant system in 802.1x protocol. If
802.1x authentication requested from supplicant system, authentication server system will check
user's name and password, authenticated by which user can visit internet. Authenticator system
refers to the device to carry out authentication such as iSpirit 3026 switch. Authenticator system
controls user for if he/she can visit internet through user's logic port (MAC Add.), user cannot
visit internet if whose logic port is not authenticated, instead he/she can make visit. Authenticator
system is a relay between supplicant system and authentication server system. Authenticator
system requests user's ID info. and forward that to authentication server system, and transmit
results authenticated by authentication server system to supplicant system. Authenticator
system should realize service system of 802.1x protocol near user system and realize supplicant
system of RADIUS protocol near authentication server system, RADIUS protocol supplicant
