802.1X ConfigurationSystem Administrator Guide4-14802.1X ConfigurationIntroduction to 802.1X and EAPThe 802.1X IEEE standard defines port-based, authenticated network access control forEthernet local area networks (LANs). With 802.1X, the user or device must pass networkaccess control by successfully authenticating with credentials, such as a name and password,or network access is denied. 802.1X uses the Extensible Authentication Protocol (EAP) torelay port access requests between LAN stations/the clients being authenticated (supplicants),Ethernet switches or wireless access points (authenticators) and RADIUS servers(authentication servers).EAP is the standard authentication mechanism carried over 802.1X. The EAP method is aninner authentication protocol that provides the secure mechanism for the authenticationexchange. Multiple EAP methods can be used. EAP methods are defined in InternationalEngineering Task Force (IETF) Requests for Comments (RFC) documents, RFC drafts, orthey can be proprietary. EAP methods have a significant influence on how your network isdesigned and implemented, because not all supplicants, not all access points, and not allRADIUS servers support all EAP methods. A careful evaluation of standards can help withselecting appropriate LAN components that will avoid vendor lock-in or dead-end technology.802.1X Configuration in CentreWare ISUse the 802.1X configuration pages in CentreWare IS to perform the following tasks.Required information varies depending on the EAP method(s) that you select.Note: Access to the 802.1x configuration pages in CentreWare IS can be restricted by thepasswords and feature authorization settings under Administrative Security.1.

Click the Advanced button for more experienced users or click the ConfigurationWizard button which will guide you through the setup.For more information, click the Help button in CentreWare IS to view the online help.6. Select EAP authentication method(s) – Select one or more authentication methods:■ MD5 Challenge■ TLS■ PEAP-MS-CHAPv2 (PEAP)If you selected a method that uses X.509 security certificates (TLS or PEAP), you can useuse a root certificate to validate the authenticating server's certificate.If you have selected TLS authentication, you must either install a signed devicecertificate that is trusted by the authenticating server, or add the device'sself-signed certificate to the authenticating server's trusted certificate store.
