Protecting Access to Privileged EXEC Commands
To disable username authentication for a specific user, use the no username name global configuration
command.
To disable password checking and allow connections without a password, use the no login line
configuration command.
Note
Configuring Multiple Privilege Levels
By default, the IOS software has two modes of password security: user EXEC and privileged EXEC. You
can configure up to 16 hierarchical levels of commands for each mode. By configuring multiple
passwords, you can allow different sets of users to have access to specified commands.
For example, if you want many users to have access to the clear line command, you can assign it
level 2 security and distribute the level 2 password fairly widely. But if you want more restricted access
to the configure command, you can assign it level 3 security and distribute that password to a more
restricted group of users.
