802.1x Application 
 
 
IEEE 802.1x port-based authentication is desired to prevent unauthorized ports 
(clients) from gaining access to the network. It is an extended authentication protocol 
that allows support of RADIUS (Remote Authentication Dial in User Service, 
RFC2138, 2139) for centralized user profile management on a network RADIUS 
server.  
We want to deploy 802.1x environment in this application. The following figure 
shows the 802.1x example. PC1(supplicant) and PC2(supplicant) want to access to the 
application server. If PC1 is not unauthorized, the traffic from PC1 to application 
server will be blocked. If PC2 is an authorized client, then it can access to the 
application server. From the figure, IES1248 acts as an authenticator.
