Parameters
cipher: Specifies to display the local password in encrypted text when you display the
current configuration.
simple: Specifies to display the local password in plain text when you display the
current configuration.
password: Password. The password must be in plain text if you specify the simple
keyword in the set authentication password command. If you specify the cipher
keyword, the password can be in either encrypted text or plain text. Whether the
password is in encrypted text or plain text depends on the password string entered.
Strings containing up to 16 characters (such as 123) are regarded as plain text
passwords and are converted to the corresponding 24-character encrypted password
(such as !TP<\*EMUHL,408`W7TH!Q!!). A encrypted password must contain 24
characters and must be in ciphered text (such as !TP<\*EMUHL,408`W7TH!Q!!).
Description
Use the set authentication password command to set the local password.
Use the undo set authentication password command to remove the local password.
Note that only plain text passwords are expected when users are authenticated.
Note:
By default, modem users and Telnet users need to provide their passwords to log in. If
no password is set, the “Login password has not been set !” message appears on the
terminal when users log in.
Examples
# Set the local password of VTY 0 to “123”.
<Sysname> system-view
System View: return to User View with Ctrl+Z.
[Sysname] user-interface vty 0
[Sysname-ui-vty0] set authentication password simple 123
