Understanding Enable and Enable Secret Passwords
Some privileged EXEC commands are used for actions that impact the system, and it is recommended
that you set a password for these commands to prevent unauthorized use. Two types of passwords, enable
(not encrypted) and enable secret (encrypted), can be set. The following commands set these passwords
and are issued in global configuration mode:
•
enable password
•
enable secret password
Using an enable secret password is recommended because it is encrypted and more secure than the
enable password. When you use an enable secret password, text is encrypted (unreadable) before it is
written to the config.text file. When you use an enable password, the text is written as entered (readable)
to the config.text file.
Each type of password is case sensitive, can contain from 1 to 25 uppercase and lowercase alphanumeric
characters, and can start with a number. Spaces are also valid password characters; for example,
“two words” is a valid password. Leading spaces are ignored, but trailing spaces are recognized.
LINE (all capital letters)
Indicates that you must enter
more than one word.
Angle brackets (< >) are not always
used to indicate that a LINE is an
argument.
<cr> (carriage return)
Indicates the end of the list of
available keywords and argu-
ments, and also indicates
when
keywords and arguments are
optional. When <cr> is the only
option, you have reached the
end of the branch or the end of
the command if the command
has only one branch.
