Configuring RADIUS
Remote Authorization Dial-In User Service (RADIUS) servers provide a centralized
802.1X or MAC-based network access control. The device is a RADIUS client that
can use a RADIUS server to provide centralized security.
An organization can establish a Remote Authorization Dial-In User Service
(RADIUS) server to provide centralized 802.1X or MAC-based 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:
• Authentication—Provides authentication of regular and 802.1X users
logging onto the device by using usernames and user-defined passwords.
• Authorization—Performed at login. After the authentication session is
completed, an authorization session starts using the authenticated
username. The TACACS+ server then checks user privileges.
Defaults
The following defaults are relevant to this feature:
• No default RADIUS server is defined by default.
