two traffics arrive at the same time.

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, IES-5000 acts as an authenticator.
