RADIUS
Remote Authorization Dial-In User Service (RADIUS) servers provide a centralized 802.1X
network access control. The device is a RADIUS client that can use a RADIUS server to provide
centralized security.
An organization can establish a RADIUS server to provide centralized 802.1X network access
control for all of its devices. In this way, authentication and authorization can be handled on a
single server for all devices in the organization.
The device can act as a RADIUS client that uses the RADIUS server for the following services:
AuthenticationProvides authentication of regular and 802.1X users logging onto the
device by using usernames and user-defined passwords.
AuthorizationPerformed at login. After the authentication session is completed, an
authorization session starts using the authenticated username. The RADIUS server then
checks user privileges.
Accounting—Enable accounting of login sessions using the RADIUS server. This enables a
system administrator to generate accounting reports from the RADIUS server.
Accounting Using a RADIUS Server
The user can enable accounting of login sessions using a RADIUS server.
The user-configurable, TCP port used for RADIUS server accounting is the same TCP port that is
used for RADIUS server authentication and authorization.
