802.1x Configuration
802.1x port-based network access control provides a method to restrict users
to access network resources via authenticating user’s information. This rest-
ricts users from gaining access to the network resources through a 802.1x-
enabled port without authentication. If a user wishes to touch the network
through a port under 802.1x control, he (she) must firstly input his (her)
account name for authentication and waits for gaining authorization before
sending or receiving any packets from a 802.1x-enabled port.
Before the devices or end stations can access the network resources through
the ports under 802.1x control, the devices or end stations connected to a
controlled port send the authentication request to the authenticator, the
authenticator pass the request to the authentication server to authenticate
and verify, and the server tell the authenticator if the request get the grant of
authorization for the ports.
According to IEEE802.1x, there are three components implemented. They are
Authenticator, Supplicant and Authentication server.
