Question about line vty

In that case, you have 16 vty lines. You can configure them one at a time (line vty 0) or all sixteen (line vty 0 15) at once.

Thank you for your answer.

but we can use this command and IOS consider it as a correct command:

line vty 0 1

or        1  3

or        4 15

or.............

Question about line vty

Think of it like an interface range command. You have 16 virtual telephony (VTY) lines available:

line vty 0

line vty 1

...

line vty 14

line vty 15

The first digit represents the first line in the range and the second is the last line in the range. Unless you have a specific need to, just configure them all at once with the 'line vty 0 15' command.
