A setting in user line view is applied only to
the user line. A setting in user line class
view is applied to all user lines of the class.
A non-default setting in either view takes
precedence over a default setting in the
other view. A non-default setting in user line
view takes precedence over a non-default
setting in user line class view.
A setting in user line class view takes effect
only for users who log in after the
configuration is completed. It does not
affect online users.
By default, password authentication is
enabled for VTY lines.
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.
