Enabling and Disabling Privilege Levels
To enable and disable privilege levels, use the following commands.
• Set a user’s security level.
EXEC Privilege mode
enable or enable privilege-level
If you do not enter a privilege level, Dell Networking OS sets it to 15 by default.
• Move to a lower privilege level.
EXEC Privilege mode
disable level-number
– level-number: The level-number you wish to set.
If you enter disable without a level-number, your security level is 1.
RADIUS
Remote authentication dial-in user service (RADIUS) is a distributed client/server protocol.
This protocol transmits authentication, authorization, and configuration 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
specified as one of the login authentication methods in the aaa authentication login command.
