In real applications, however, deploying EAD clients proves to be timeconsuming and inconvenient.To address the issue, the Switch 4200G provides the forcible deployment of EAD clients with 802.1xauthentication, easing the work of EAD client deployment.Operation of Quick EAD DeploymentQuick EAD deployment is achieved with the two functions: restricted access and HTTP redirection.Restricted accessBefore passing 802.1x authentication, a user is restricted (through ACLs) to a specific range of IPaddresses or a specific server. Services like EAD client upgrading/download and dynamic addressassignment are available on the specific server.HTTP redirectionIn the HTTP redirection approach, when the terminal users that have not passed 802.1x authenticationaccess the Internet through Internet Explorer, they are redirected to a predefined URL for EAD clientdownload.The two functions ensure that all the users without an EAD client have downloaded and installed onefrom the specified server themselves before they can access the Internet, thus decreasing thecomplexity and effort that EAD client deployment may involve.The quick EAD deployment feature takes effect only when the authorization mode of an 802.1x-enabledport is set to auto.
