HTTP redirection
In the HTTP redirection approach, when the terminal users that have not passed 802.1x
authentication access the Internet through Internet Explorer, they are redirected to a
predefined URL for EAD client download.
The two functions ensure that all the users without an EAD client have downloaded and
installed one from the specified server themselves before they can access the Internet,
thus decreasing the complexity and effort that EAD client deployment may involve.
The quick EAD deployment feature takes effect only when the access control mode of an
802.1x-enabled port is set to auto.
