This
is considered to be
a relatively weak
algorithm, and can
be cracked easily.
Therefore it is
imperative to use
other methods to
secure your routers
than just password
encryption.
92 Setting Cisco Passwords and Password Security
Router(config)#no service password-encryption Turns off password
encryption
NOTE: If you use
the service passwordencryption
command to
encrypt your passwords,
and then turn password
encryption off with the
no service passwordencryption
command,
your passwords will
remain encrypted;
new passwords will be
unencrypted, except
for the enable secret
password, which is
always encrypted with
the MD5 algorithm.
Router(config)#security passwords min-length 10 Sets a requirement for all
user/enable passwords to
be a minimum of ten
characters in length
NOTE: This command
was introduced in Cisco
IOS Release 12.3(1).
Range is from 0 to 16
characters. Existing
router passwords are
not affected by this
command. It is highly
recommended to set a
minimum password
length of at least ten
characters.
Router(config)#username roland password
darktower
Creates a locally stored
password of darktower for
the username roland. The
password is unencrypted
but can be encrypted with
the service passwordencryption
command.
