Command Usage
◆ You cannot set a null password. You will have to enter a password to change the
command mode from Normal Exec to Privileged Exec with the enable
command.
◆ The encrypted password is required for compatibility with legacy password
settings (i.e., plain text or encrypted) when reading the configuration file
during system bootup or when downloading the configuration file from an FTP
server. There is no need for you to manually configure encrypted passwords.
