Parameter
simple: Plain text password.
cipher: Encrypted password.
password: If password form is set to simple, the parameter password must be in
plain text. If the password form is set to cipher, the password can be either in
encrypted text or in plain text depending on what has been input. A plain-text
password can be a string of no more than 16 consecutive characters, 1234567 for
example. An encrypted password, however, must be of 24 characters in length
and must be in ciphertext, _(TT8F]Y\5SQ=^Q`MAF4<1!! for example.
Description
Using the set authentication password command, you can set a local
authentication password. Using the undo set authentication password command,
you can remove the local authentication password.
Regardless of whether the password format is set to plain text or ciphertext, a user
must input plain text password during the authentication.
When configuring a password, you must specify its format to simple or cipher. If
the former has been specified, the password saved in the configuration file will be
in plain text. If the latter is specified, however, the password will be displayed in
ciphertext regardless of whether the password you enter is a simple password of 1
to 16 bytes or an encrypted password of 24 bytes.
By default, Telnet users is required to undergo login password authentication
(which can be set by using the authentication-mode password command). If no
password has been configured, the following information will be displayed:
password required, but none set
For related command, see authentication-mode.
Example
