Usage guidelines
When the authentication mode is
none
, any user can log in without authentication. To improve device
security, use the password or scheme authentication mode.
In VTY line view, this command is associated with the
protocol inbound
command. If you specify a
non-default value for only one of the two commands in VTY line view, the other command uses the
default setting, regardless of the setting in VTY line class view.
Examples
# Enable the
none
authentication mode for user line VTY 0.
<Sysname> system-view
[Sysname] line vty 0
[Sysname-line-vty0] authentication-mode none
# Enable password authentication for user line VTY 0 and set the password to
321
.
<Sysname> system-view
