hi,
cant we just use line console command instead of using line console 0 command?
i mean is there any point of using line console 0? can we use more than one console? if yes how?

Hi Vishal,
The use of "line console 0" command is to connect a switch/router through medium console. If there is only one console port, you can only choose "line console 0". However if you have more than the number goes as 1,2,3,4 ... You can set different or same password to all your console ports.

Naidu.

means you are saying switch or router can have more than one console port?
my understanding is line console 0 means i can connect one laptop to switch/router. 1,2,3,4 console means i can connect 1,2,3,4 laptops. is it rite?

Dear Vishal
on switch we are having only one console ports ,so we are starting it with 0(zero) that is console 0 .If we have more than one then we can have console 1 option.

I believe that it would help if we think about the various parameters in the command one at a time:
1) line. This parameter specifies that we will be configuring some type of access port. Note that there can be multiple types of access ports including console, aux, and vty. The line command requires 2 additional parameters.
2) console. This parameter specifies that we will be configuring access via the console port.
3) 0. This parameter specifies which (if there are alternatives) port we will be configuring. Since there is physically only a single console port we always use 0 for the console and the parameter is almost superfluous. But the line command requires 2 additional parameters be input and we must use something here. This parameter is essential if we are configuring the vty and trivial if we are configuring the console.

To connect through console medium, you use the "line console 0" command. The first two word represents the actual code whereas the last part represents the console port.
However, since there is only one console port, we use line console 0.

You would use line console 1 or line console 2 if you had a terminal server connected to you switches

In IOS there is only "" line consol 0 "" option so how come we use line consol 1,2,3 if we have a terminal server option.
