Fast Ethernet Switch User’s Guide
802.1x
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 6-28. 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.

The user’s information, including account number, password, and configuration details such
as IP address and billing information, is stored in a centralized RADIUS server.
