Concept Guide
Congure 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 congured 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 EMC 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 conguration information between a central RADIUS server and a RADIUS client
(the Dell EMC 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 EMC Networking OS supports RADIUS for user authentication (text password) at login and can be specied as one of the login
authentication methods in the aaa authentication login command.
When conguring AAA authorization, you can congure to limit the attributes of services available to a user. When you enable
authorization, the network access server uses conguration information from the user prole to issue the user's session. The user’s access
is limited based on the conguration attributes. RADIUS exec-authorization stores a user-shell prole and that is applied during user login.
You may name the relevant named-lists with either a unique name or the default name. When you enable authorization by the RADIUS
server, the server returns the following information to the client:
