line, tty, vty, differences

binarysoul

Here is the output:

Router(config)#line ?

<0-70> First Line number
aux Auxiliary line
console Primary terminal line
tty Terminal controller
vty Virtual terminal
x/y Slot/Port for Modems

Is 0-70 is for number of telnet sessions that can be opened to the router? Is telnet enabled by default? Also, what's the differency between tty and vty. Thanks

No. Those are physical connections. The number of telnet sessions is controlled by the number of virtual connections.

No. You have to set up login and password.

TTY lines are physical connections. VTY lines are virtual connections.
