Cisco Terminal Server Configuration Example

Hi,
That very well explained, but I just have one question. This brief representation below is to give you an idea on I’m about to explain.
R1->R2->X1, X2, X3
We have one terminal server, Which R1 represent, set up in my workplace and I would like to use one octal cable to plug in another router, R2, which will have couple of switches(X1,X2,X3) connected to it for my CCNP switch practice. The issue I have is when I’m consoled into one of the switches and want to move to another switch, I usually type CTR+SHIFT+6 and then X, but this command send me back to the R1 instead of R2 And if I clear the line and try to console back to R2, it automatically send me to the switch I was consoled into last, it skip R2. To be able to console to R2 and get to a different switch, I’ll have to reboot it every time. I just want to know if there a more efficient way to move around the switches or connect to them simultaneously.
