802.1X Re-authentication
802.1X Re-authentication re-authenticates users that already pass authentication using
timer or message trigger. With 802.1x Re-authentication enabled, the switch periodically
checks users' connection status. If a user is detected not responding to re-authentication
messages for a certain time length, then it will be disconnected. If it wishes to reconnect to
the device, it must initiate an 802.1x authentication again via client software.

802.1X Access Control Method
This device supports port based access control method. When port based access control
is adopted, as long as the first user connected to this port is authenticated successfully,
other users accessed can use network resources without being authenticated. However, if
the first user is disconnected, and when the re-authentication time is up, other users will
be unable to access the Internet.
802.1X includes the following three parts: 802.1X Global Setup, 802.1X Port Setup,
802.1X Port Statistics.
