D-Link DGS-3224SR Layer 2 Gigabit Ethernet Switch

Port Access Entity

802.1X Port-based Network Access Control

The Switch is an implementation of the server side of IEEE 802.1X-Port Based Network Access Control.
Through this mechanism, users have to be authorized before being able to access the network. See the following
figure:

Figure 17-2. Typical 802.1X Configuration Prior to User Authentication

Once the user is authenticated, the switch unblocks the port that is connected to the user as shown in the next
figure.
