RADIUS Roaming Out / 802.1x Authentication:
When RADIUS Roaming Out is enabled, this system
becomes a RADIUS server for other external RADIUS clients. The Local user with RADIUS roaming out
permission need to be configured in the Radius Client List first. The Local user in the list may then log on the
system via the other domain, such as a branch office, as long as the RADIUS clients are configured
accordingly. Selecting either of the options will bring up the hyperlink called
RADIUS Client List

802.1x Authentication:
802.1x is a security standard for wired and wireless LANs. It encapsulates EAP
(Extensible Authentication Protocol) processes into Ethernet packets instead of using the protocol's native
PPP (Point-to-Point Protocol) environment, thus reducing some network overhead. It also puts the bulk of the
processing burden upon the client (called a supplicant in 802.1x parlance) and the authentication server
(such as a RADIUS), letting the "authenticator" middleman simply pass the packets back and forth.
