User Authentication

Remote Authentication Dial In User Service (RADIUS, RFC 2138) is a mechanism for authenticating and
centrally administrating access to network nodes. The ExtremeWare XOS RADIUS client
implementation allows authentication for Telnet or console access to the switch.
Extreme switches are also capable of sending RADIUS accounting information. You can configure
RADIUS accounting servers to be the same as the authentication servers, but this is not required.
Terminal Access Controller Access Control System Plus (TACACS+) is a mechanism for providing
authentication, authorization, and accounting on a centralized server, similar in function to the RADIUS
client. The ExtremeWare XOS version of TACACS+ is used to authenticate prospective users who are
attempting to administer the switch. TACACS+ is used to communicate between the switch and an
authentication database.
NOTE
You cannot use RADIUS and TACACS+ at the same time.
