Introduction to the Junos CLI-WBT

Introduction to the Junos CLI-WBT 
Introduction to the Junos CLI-WBT
You have probably heard of the Juniper Networks Junos operating system, and you have maybe even used it a bit. In this course, you find out what the excitement is all about.

Designed as an introductory course for anyone interested in learning about the Junos OS, this course covers all the basics of the Junos OS and the command-line interface (CLI). This course is intended as an introduction to the Junos OS and is not meant to be comprehensive.

This course also offers hands-on interactive labs to practice what you have learned. Not simply prescribed exercises, these labs offer you a “sandbox” that allows you to play with the CLI as if it were connected to a real device. You see what happens when you enter commands correctly—and incorrectly. The sandbox is the perfect practice environment.
