Therefore, the RADIUS server must have an entry for this username.
Obscuring Passwords and Keys
By default, the service password-encryption command stores encrypted passwords. For greater
security, you can also use the
service obscure-passwords command to prevent a user from reading the
passwords and keys, including RADIUS, TACACS+ keys, router authentication strings, VRRP authentication by
obscuring this information. Passwords and keys are stored encrypted in the configuration file and by default
are displayed in the encrypted form when the configuration is displayed. Enabling the service obscure-
passwords command displays asterisks instead of the encrypted passwords and keys. This command
prevents a user from reading these passwords and keys by obscuring this information with asterisks.
Password obscuring masks the password and keys for display only but does not change the contents of the
file. The string of asterisks is the same length as the encrypted string for that line of configuration. To verify
that you have successfully obscured passwords and keys, use the show running-config command or
show startup-config command.
If you are using role-based access control (RBAC), only the system administrator and security administrator
roles can enable the service obscure-password command.
To enable the obscuring of passwords and keys, use the following command.
• Turn on the obscuring of passwords and keys in the configuration.

AAA Authorization
Dell Networking OS enables AAA new-model by default.
You can set authorization to be either local or remote. Different combinations of authentication and
authorization yield different results. By default, Dell Networking OS sets both to local.
Privilege Levels Overview
Limiting access to the system is one method of protecting the system and your network. However, at times,
you might need to allow others access to the router and you can limit that access to a subset of commands.
In Dell Networking OS, you can configure a privilege level for users who need limited access to the system.
Every command in Dell Networking OS is assigned a privilege level of 0, 1, or 15. You can configure up to 16
privilege levels in Dell Networking OS. Dell Networking OS is preconfigured with three privilege levels and you
can configure 13 more. The three preconfigured levels are:
