Specifying LINE Mode Password and Privilege
You can specify a password authentication of all users on different terminal lines.
The user’s privilege level is the same as the privilege level assigned to the terminal line, unless a more specific privilege level is assigned to
the user.
To specify a password for the terminal line, use the following commands.
• Configure a custom privilege level for the terminal lines.
LINE mode
privilege level level
○ level level: The range is from 0 to 15. Levels 0, 1, and 15 are pre-configured. Levels 2 to 14 are available for custom
configuration.
• Specify either a plain text or encrypted password.
LINE mode
password [encryption-type] password
Configure the following optional and required parameters:
○ encryption-type: Enter 0 for plain text or 7 for encrypted text.
○ password: Enter a text string up to 32 characters long.
To view the password configured for a terminal, use the show config command in LINE mode.
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.
