will go via 0/34. And the 0/33 get the higher priority. The video traffic will go first when the 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, IES1248 acts as an authenticator.
