In the Fig. 3-58, this is the typical configuration, a single supplicant, an authenticator and an 
authentication server. B and C are on the internal network, D is the Authentication server running 
RADIUS, the switch at the central location acts as the Authenticator connecting to PC A and A is 
a PC outside the controlled port, running Supplicant PAE. In this case, PC A wants to access the 
services on device B and C, first, it must exchange the authentication message with the 
authenticator on the port it is connected via EAPOL packet. The authenticator transfers the 
supplicant’s credentials to the Authentication server for verification. If successful, the 
authentication server will tell the authenticator to grant access. PC A  is then allowed to access B 
and C via the switch. If there are two switches directly connected together the link connecting the 
two switches, may have to act as two port roles at the end of the link: authenticator and 
supplicant, because the traffic is bi-directional. 
 
 
 
 
 
 
 
Only MultiHost 802.1X authentication is supported in the GSM Series switches. In this mode 
devices connected to an 802.1x enabled port, can access network resources once the supplicant 
has been authenticated.
