Web: Configuring IEEE 802.1x<br />

<strong>Access</strong> <strong>Point</strong> Configuration<br />

Configuring <strong>Wireless</strong> Security<br />

The access point supports IEEE 802.1x (802.1x) access control for wireless<br />

clients. This control feature prevents unauthorized access to the network by<br />

requiring an 802.1x client application to submit user credentials for authentication.<br />

Client authentication is then verified by a RADIUS server using Extensible<br />

Authentication Protocol (EAP) before the access point grants a client<br />

access to the network.<br />

Not e The 802.1x access control feature requires a RADIUS authentication server to<br />

be configured and available in the wired network. Be sure that the server’s<br />

details are configured in the RADIUS window.<br />

The access point also uses the 802.1x Extensible Authentication Protocol Over<br />

LANs (EAPOL) packets to pass dynamic unicast session keys and static<br />

broadcast keys to wireless clients. Session keys are unique to each client and<br />

are used to authenticate a client connection, and correlate traffic passing<br />

between a specific client and the access point. You can also enable broadcast<br />

key rotation, so the access point provides a dynamic broadcast key and<br />

changes it at a specified interval.<br />

The Authentication window on the Security tab enables 802.1x to be configured<br />

for the access point.<br />

The web interface enables you to modify these parameters:<br />

802.1x Setup. You can enable 802.1x as optionally supported or as required<br />

to enhance the security of the wireless network. When 802.1x is enabled, the<br />

broadcast and session key rotation intervals can also be configured.<br />

■ Disable: The access point does not support 802.1x authentication for any<br />

wireless client. After successful wireless association with the access<br />

point, each client is allowed to access the network.<br />

■ Supported: The access point supports 802.1x authentication only for<br />

clients initiating the 802.1x authentication process (the access point does<br />

not initiate 802.1x authentication). For clients initiating 802.1x, only those<br />

successfully authenticated are allowed to access the network. For those<br />

clients not initiating 802.1x, access to the network is allowed after<br />

successful wireless association with the access point.<br />

■ Required: The access point enforces 802.1x authentication for all associated<br />

wireless clients. If 802.1x authentication is not initiated by a client,<br />

the access point will initiate authentication. Only those clients successfully<br />

authenticated with 802.1x are allowed to access the network.<br />
