• Move to a lower privilege level.

RADIUS
Remote authentication dial-in user service (RADIUS) is a distributed client/server protocol.
This protocol transmits authentication, authorization, and conguration information between a central RADIUS server and a RADIUS
client (the Dell Networking system). The system sends user information to the RADIUS server and requests authentication of the
user and password. The RADIUS server returns one of the following responses:
• Access-Accept — the RADIUS server authenticates the user.
• Access-Reject — the RADIUS server does not authenticate the user.
If an error occurs in the transmission or reception of RADIUS packets, you can view the error by enabling the debug radius
command.
Transactions between the RADIUS server and the client are encrypted (the users’ passwords are not sent in plain text). RADIUS
uses UDP as the transport protocol between the RADIUS server host and the client.
For more information about RADIUS, refer to RFC 2865, Remote Authentication Dial-in User Service.
RADIUS Authentication
Dell Networking OS supports RADIUS for user authentication (text password) at login and can be specied as one of the login
authentication methods in the aaa authentication login command.
