By default, the Telnet server function is
disabled.
Use either command.
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 view takes effect
immediately and affects the online user. A
setting in user line class view does not
affect online users and takes effect only for
users who log in after the configuration is
completed.
By default, password authentication is
enabled for VTY lines.
In VTY line view, this command is
associated with the protocol inbound
command:
•
If the setting of either command is not
the default in VTY line view, the setting
of the other command in VTY line view
takes effect.
•
If the settings of both commands are the
defaults in VTY line view, the settings of
the commands in VTY line class view
take effect.
By default, a VTY line user of the default
MDC is assigned the user role
network-operator, and a VTY line user of a
non-default MDC is assigned the user role
mdc-operator.
