By default, Cisco routers have three authorization levels: null, user, and privileged. Access to level zero allows only five commands: log out, activate, deactivate, assist and stop. The user level level 1 provides very limited read access to the router and the privileged level level 15 provides complete control over the router.
Explanation: There are no login commands that allow users to telnet to a router without a password. Also, it is not possible to switch to privileged mode via Telnet this is the IOS EXEC mode that allows you to view or change the configuration of a router unless an activation password has been defined.

You cannot enable line vty 10 without enabling line vty 9. If you want to enable line vty 9, then you can enter the command line vty 9 in global mode or line mode , such as: config line vty 9 so that the system will automatically enable the previous lines.
Of course, you can directly enter line vty 0 9 to directly enable 10 lines. If you do not want to open so many lines for users to use, you only need to use the no line vty m [n] command in global mode to close the line after the mth line. At this time, the value of n is optional, because the system only allows Turn on the continuous line number, cancel the mth line will automatically cancel all subsequent lines. Console port is used to connect a computer directly to a router or switch and manage the router or switch since there is no display device for a router or switch.

Category: technology and computing computer networking. They are virtual, in the sense that they are a function of software - there is no hardware associated with them.
