Junos Security

Chapter 3. Hands-On Junos

This chapter is designed as a jumpstart for users who are getting into Junos for the first time. It is by no means meant to be a complete primer on Junos and all of its various features; rather, it is intended to provide administrators who are new to Junos with enough tools to get started on the SRX Series—and hopefully provide long-time Junos users with a few new tips that are specific to the SRX.

If you’re coming from another network operating system such as IOS or ScreenOS, this chapter will get you started in Junos.

Lately, Juniper Networks has created an abundance of great tools designed to enable customers to manage the platform via other management tools, including Junos Space, the Network and Security Manager (NMS), and Junos automation techniques. We will discuss these and other management tools in other chapters of this book. This chapter provides a tour of the Junos CLI, and how to jump right in.

Why promote the CLI? First, no matter which tool you use to manage Junos, the tool will always be represented in the CLI. So, it’s important to have an understanding of the CLI, configuration output, and how the CLI works. This will give you a better understanding of what is going on inside the Junos device, no matter which management method you decide to use.
