Juniper Networks JNCIA-Junos (JN0-102): User Interfaces

Course Overview
Hi everyone. My name is Rich Bibby, and welcome to my course, Juniper Networks JNCIA-Junos: User Interfaces. I'm a network engineer based in Manchester in the UK. This course is for network engineers and other IT professionals looking to gain a solid understanding of the user interface options for administering the Junos OS from Juniper Networks. This course is one of a complete series covering the Juniper Networks JNCIA-Junos certification, providing you with the skills and knowledge required to the pass the exam. Some of the major topics that we will cover include CLI functionality, including modes, navigation, and how to get help; understanding the concepts in active and candidate configuration files, and how to make changes to the configuration; how to revert previous versions of the configuration; and how to work with files in Junos. We'll also look at the J-Web interface functionality. By the end of this course, you'll have taken another big step towards gaining the JNCIA-Junos certification, one of the most sought after in the networking industry. All you need to have is a basic understanding of the fundamentals of networking before taking this course. From you here you can continue your learning with the rest of the courses in this series. I hope you'll join me on this journey to learn how to manage and configure Juniper network devices on the Juniper Networks Junos: User Interfaces course, at Pluralsight.

CLI Functionality - Modes, Navigation, and Help
Hello, and welcome to the first module of the Juniper Networks JNCIA-Junos: User Interfaces course. This course is part of a series designed to take you through everything you need to know to gain the JNCIA-Junos certification from Juniper Networks. These days there are many ways that network engineers can manage and make configuration changes to network devices. In fact, the last few years have seemed to move away from the traditional model of the network engineer typing away at the command line, to more automated methods of network administration, using things like scripting in languages such as Python, for example. However, for the purposes of the JNCIA-Junos exam, you need to have a firm grasp of the traditional method of entering commands via the trusty command line interface. I'd say as well that if you're new to Juniper or indeed to networking in general, then learning how to work the CLI to get the job done is still absolutely essential. As a network engineer, I still spend the vast majority of my time administering networks using the CLI. So in this module, we get hands on with the Junos CLI and learn how to use it to get the job in the most efficient way possible. In this module, and indeed the whole course, the goal is to spend as much time as possible configuring live network kit, so let's run through what you'll learn in this module. Firstly, we'll take a look at what the CLI is and how we go about logging in to a Juniper device to access it. Next, we'll dive into the first of the two CLI modes that you can work in, which is operational mode. Then we'll take an in-depth look at the other mode, which is known as configuration mode. Lastly, we'll take a look at some ways that you can save time when working by using some shortcuts, and also how to get help from within Junos when you can't remember how to complete a command or achieve a particular configuration task.

Active vs. Candidate Configuration
Hello, and welcome to this module of the Juniper Networks JNCIA-Junos: User Interfaces course. This course is part of a series of courses designed to take you through everything you need to know to gain the JNCIA-Junos certification from Juniper Networks. In the previous module, we looked at the two different command line modes. Operational mode is where we do things like monitor the hardware and software, troubleshoot problems, and perform maintenance and system upgrades. And configuration mode is where we actually make changes to the way the device operates. In this module, we'll take a much deeper look at configuration mode and the concepts of the active and candidate configurations. So, let's just run through what you'll learn in this module. Firstly, we'll discuss the differences between the active and the candidate configurations, and how to enter configuration mode. Then we'll look at the basic commands used to make changes to the configuration. And lastly, we'll talk about how to work smarter and save time when making configuration changes.

Committing Configuration Changes
Hello, and welcome to this module of the Juniper Networks JNCIA-Junos: User Interfaces course. This course is part of a series designed to take you through everything you need to know to gain the JNCIA-Junos certification from Juniper Networks. Moving on from the previous module, in this module we're going to take a look the process of making your candidate configuration changes live. In other words, making your changes become the active configuration. So, let's run through what you'll learn in this module. Firstly, we'll take a quick look at how you can verify the changes that you have made to the candidate configuration file. And then once we're happy that the candidate configuration is good and we're ready to commit our changes, we'll examine how to do this, so our change becomes active. Lastly, we'll look at a really great Junos feature, which is configuration rollback, and we'll look at how this can help you out when your change hasn't gone according to plan and you need to roll it back. Because let's be realistic, we all make mistakes.

Working with Configuration Files
Hello, and welcome to this module of the Juniper Networks JNCIA-Junos: User Interfaces course. This course is part of a series designed to take you through everything you need to know to gain the JNCIA-Junos certification from Juniper Networks. In this module, we're going to look at how you can work with configuration files in Junos, specifically in relation to making configuration changes. So let's run through what you'll learn in this module. Firstly, we'll take a look at the file and folder structure on a Juniper device, and explore where files are saved when you work with them and the ways in which you can view their contents. Secondly, we'll look at the options you have when it comes to saving files, either locally onto the router or switch itself or remotely on a file server. And lastly, we'll look at the options you have when it comes to loading files, again, either from the local storage on the Juniper device itself or from a remote file server.

J-Web - Core and Common Functionality
Hello again, and welcome to this module of the Juniper Networks JNCIA-Junos: User Interfaces course. This course is part of a series of courses designed to take you through everything you need to know to gain the JNCIA-Junos certification from Juniper Networks. So far this course has focused on the command line interface, or CLI, as the user interface for monitoring and configuring Juniper devices, but there is another interface that is available to perform the same tasks, and that is the J-Web graphical user interface. It isn't an area that is focused on heavily for the exam, but it's certainly worth learning a little about, and in this module we'll introduce you to it so you're at least familiar with it and what it can do. So, let's run through what you'll learn in this module. Firstly, we'll talk about what the J-Web GUI is and how it to enable it on a device running Junos, and how to access it once it's enabled. Then in our demo we'll configure our device to enable the J-Web interface, and we'll log on to it and explore each of the tabs that you have access to. Then we'll look at how to perform some basic tasks like we've done already via the CLI, so you can see how the two user interfaces compare, such as creating a user and configuring an interface. And then we'll wrap up by taking a look at some of the troubleshooting options that you can also access from within J-Web.
