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 are required to undergo login password authentication
(which can be set by using the
authentication-mode password
command). If

Some constraints are put on the

(AUX and CON shares the same port), the AUX will not support this command
as well. These constraints do not apply to other types of user interfaces.
