settings as encrypted. A plain text password is a sequential character string of no 
more than 16 digits, for example, 3Com918. The length of an encrypted password 
must be 24 digits and in encrypted text, for example,

of whether the configuration is plain text or cipher text.

password has not been set, the following prompt is displayed:
