IEEE 802.1X
802.1X is an IEEE Standard for Port-based Network Access Control that provides an
authentication mechanism to devices that wish to attach to a LAN or WLAN.
Port-based network access control protocol contains 3 parts, supplicant, authenticator, and
authentication server.
With 802.1X authentication, a username can be linked with an IP address, MAC address, and port.
802.1X also provides more security because it only allows traffic transmitting on authenticated
ports or MAC addresses.
Radius
RADIUS is used in the authentication process.
Database of authorized users is maintained on a RADIUS server.
Allowing or denying the requests decides if the client can connect to a LAN/WAN or not.
802.1X Setting
IEEE 802.1X is the protocol that provides authentication to obtain access to IEEE 802 LANs.
It is port-base network access control. The switch can control which connection is available or
not.
