Client
The Client is simply the endstation that wishes to gain access to the LAN or switch services. All end stations must be running
software that is compliant with the 802.1X protocol. For users running Windows XP and Windows Vista, that software is included
within the operating system. All other users are required to attain 802.1X client software from an outside source. The Client will
request access to the LAN and or Switch through EAPOL packets and, in turn will respond to requests from the Switch.

Authentication Process
Utilizing the three roles stated above, the 802.1X protocol provides a stable and secure way of authorizing and authenticating
users attempting to access the network. Only EAPOL traffic is allowed to pass through the specified port before a successful
authentication is made. This port is “locked” until the point when a Client with the correct username and password (and MAC
address if 802.1X is enabled by MAC address) is granted access and therefore successfully “unlocks” the port. Once unlocked,
normal traffic is allowed to pass through the port. The following figure displays a more detailed explanation of how the
authentication process is completed between the three roles stated above.
Figure 5 - 22. 802.1X Authentication Process
The D-Link implementation of 802.1X allows network administrators to choose between two types of Access Control used on the
Switch, which are:
1. Port-based Access Control – This method requires only one user to be authenticated per port by a remote RADIUS server
to allow the remaining users on the same port access to the network.
2. Host-based Access Control – Using this method, the Switch will automatically learn up to sixteen MAC addresses by port
and set t hem i n a list. Each MAC ad dress must b e au thenticated by th e Switch using a remote RADIUS serv er before
being allowed access to the Network.
