5.14 802.1X
802.1X is an IEEE Standard for Port-based Network Access Control. It provides an authentication
mechanism to devices that wish to attach to a LAN or WLAN. This port-based network access
control protocol contains 3 parts, supplicant, authenticator, and authentication server. With 802.1X
authentication, we can link a username with an IP address, MAC address, and port. This provides
greater visibility into the network. 802.1X also provides more security because it only allows traffic
transmitting on authenticated ports or MAC addresses. Although the IEEE standard defined it as a
“Port-based” control, to provide more robust service, Antaira implements all managed switches with
802.1X to a “MAC-based” access control.
RADIUS
RADIUS is used in the authentication process. Database of authorized users is maintained on a
RADIUS server. There is an authenticator, our switch enabling 802.1X, to forward the
authentication requests between authentication (RADIUS) server and client. Allowing or denying the
requests decides if the client can connect to a LAN/WAN or not.
