90 Setting Cisco Passwords and Password Security
Setting Cisco Passwords and Password Security
Router(config)#enable password cisco Sets the enable password
to cisco
Router(config)#enable secret class Sets the enable secret
password to class
CAUTION: The enable
secret password is
encrypted by default.
The enable password
is not. For this reason,
recommended practice
is that you never use
the enable password.
Use the enable secret
password only in a
router con?¬?guration.
CAUTION: You should
not set both the enable
password and the
enable secret password
to the same password.
Although Cisco IOS
will warn you to change
your enable secret
password, it will accept
the same password.
Doing do defeats the
use of the encryption
feature of the enable
secret password.
