IEEE 802.1X Authentication
If a device tries to connect and start communicating on an 802.1X network, the device must go through user
authentication in order to prove that the connection is made by an authorized user. Authentication information
is sent to and checked by a RADIUS server, which permits or rejects communication to the network depending
on the authentication result. If authentication fails, a LAN switch (or an access point) blocks access from the
outside of the network. The machine can connect to an 802.1X network as a client device. Configuring the
