(2) The user accesses any Website through the browser (Write down the domain name, not the IP address, in
the host part of the url column in the browser), which activates the DNS request of the user computer.
(3) The DNS server returns the user a request response. The switch captures the request response message
and changes the resolved address to the address of the built-in portal server in the switch.
(4) The DHCP confirmation process continues after the browser captures DNS resolution. The switch returns
the corresponding authentication page according to different authentication methods after the switch
receives the request.
(5) The user submits the authentication request; the switch authenticates the user through the AAA server
after the switch receives information submitted by the user; if the authentication succeeds, the AAA server
will be notified to start charging; the switch gives the user the network access right and returns the user a
page that the authentication is successful; meanwhile, the switch also returns a keep alive page, which
periodically sends the user online notification to the switch.
(6) The user sends the logout request to the switch through the browser. The switch then notifies the AAA
server to stop charging, and withdraws the network access right from the user.
(7) In the period between successful user authentication and logout, the switch periodically detects the user
online notification. If the notification is not received in the preset time, the switch considers that the user
abnormally logs off, notifies the AAA server to stop charging and withdraws the network access right from
the user.
The above steps may vary a little with configuration strategies and users operations. For example, if user
directly accesses the portal server of the switch before the authentication is approved, DNS-related
processes will not be enabled.
