CLI Prompts

It’s really important that you understand the different prompts you can find when configuring a

router. Knowing these well will help you navigate and recognize where you are at any time within

configuration mode. In this section, I’m going to demonstrate the prompts that are used on a Cisco

router and discuss the various terms used. (Always check your prompts before making any changes

to a router’s configuration!)

I’m not going into every different command prompt offered, because doing that would be

reaching beyond the scope of this book. Instead, I’m going to describe all the different prompts

you’ll see throughout this chapter and the rest of the book. These command prompts really are the

ones you’ll use most in real life anyway; plus, they’re the ones you’ll need to know for the exam.

Don’t freak! It’s not important that you understand what each of these com-

mand prompts accomplishes yet because I’m going to completely fill you in

on all of them really soon. So right now, just relax and focus on becoming

familiar with the different prompts available and all will be well!
