In order to get Junos network devices up and running you need to learn about the main configuration elements for Junos devices and how to configure the basic parameters of a Junos network. In this course, Juniper Networks JNCIA-Junos (JN0-102): Junos Configuration Basics, you will first learn about the default state and configuration that you will find on a Junos device when it has been powered on for the first time. Then, you'll look at how to get the device up and running with some initial configuration tasks. Next, you will explore user authentication and the types of user accounts and classes that can be set up on a Junos device and how to configure them. After that, you will learn about the different interface types, what their function is, and how to configure them, including using configuration groups. Finally, you will learn about the different types of log files that are generated on a Juniper device and how to access them. You will also look at how to enable trace options to help troubleshoot problems on a network. Throughout the course you will get hands-on and configure all of this in your lab environment. When you’re finished with this course, you will have taken another step towards gaining Juniper Networks JNCIA-Junos certification, one of the most sought after in the industry.

Course Overview
Hey everyone, my name is Rich Bibby and welcome to my course, Juniper Networks: Junos Configuration Basics. I'm a network engineer based in Manchester in the UK. This course is for network engineers and other IT professionals looking to understand how to take a Juniper device from out of the box, get the basics configured and then manage and monitor it as part of your production network. This course is one of a complete series covering the Juniper Network's JNCIA Juno Certification providing you with all the skills and knowledge required to pass the exam. Some of the major topics that we will cover include the factory default settings, how to get the device up and running with some initial configuration tasks, user authentication, the different types of interfaces and how to configure them, extra features like NTP, SNMP and configuration archival and how to work with system log files. By the end of this course, you will have all the skills and knowledge needed to get a Junos device up and running on your network in the shortest amount of time. You will have also taken another big step towards gaining the Juniper network's JNCAA 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. So I hope you'll join me on this journey to learn how to get a Juniper device up and running as quickly as possible with the Juniper Network's Junos Configuration Basics Course at Pluralsight.

Factory Default State and Initial Configuration
Hello and welcome to this first module of the Juniper Networks JNCIA Junos Configuration Basics Course. This course is one in a series of courses designed to take you through everything you need to know to gain the JNCIA Junos Certification from Juniper Networks. So let's run through what you'll learn in this module. Firstly, we'll talk about the factory default state and how this can vary, depending on the hardware platform. We'll look at how to load a factory default configuration and how to logon to it in this state with the root account. And we'll also look at how to perform a graceful shutdown of your Junos device. Then we'll talk about the basic system settings that need to be configured to get your device up and running. These will include the hostname, the system time, system services like SSH and Telnet, configuring a login message that users will see when they connect to your device, how to configure the management IP address and routing, how to set up a backup router, and finally, once this basic configuration has been set, how to make this your rescue configuration, so you can easily rollback to it should you need to.

User Authentication
Hello and welcome to this module of the Juniper Networks JNCIA Junos Configuration Basics Course. In this module, you will learn all about user authentication with Junos and how to configure everything you need to set up access for your users to your network devices. So let's run through what you'll learn in this module. Firstly, we'll look at the most basic method of user authentication, which is authenticating users against a local database of user accounts stored on the device itself. Then you'll learn about how you can control the level of access that users have to your system by assigning them to a login privilege class. The classes range from no access through to full access with all privileges. So we'll explain these and also look at how to create your own custom classes. Finally, we'll take a look at how centralized authentication works, where users are authenticated against a central server that could be running TACACS+ or RADIUS; and, as always, we'll get hands on and configure all of this in our lab.

Interface Types and Properties
Hello and welcome to this module of the Juniper Network's JNCIA-Junos Configuration basics course. This module is all about interface types and properties. So let's run through what you'll learn in this module. Firstly, we'll talk about what an interface is and the various types of interfaces that you will find on Juniper Networks devices. Then, we'll take a look at the naming conventions used for identifying interfaces and we'll step through some examples of these so you get familiar with them. After this, we'll look at the physical and logical properties of Juniper interfaces. And finally, how you go about configuring and also monitoring them. And, as always, we'll get hands on and configure some example interfaces in our lab.

Extra Initial Configuration Elements – NTP, SNMP, Configuration Archiving
Hello, and welcome to this module with the Juniper Networks JNCIA Junos configuration basics course. In this module you'll learn all about some of the extra settings you can configure on Juniper devices to help you manage your network. So, let's run through what you'll learn in this module. Firstly, we'll look at the Network Time Protocol NTP. We'll talk about the importance of having accurate time across your network devices, and how you configure Junos to use an NTP server. Then you'll learn about the Simple Network Management Protocol or SNMP. We'll talk about what we use this for, and then look at how to configure Juno's for SNMP. Finally, we'll take a look at configuration archival with Junos, and the different options we have, for copying our configuration files onto remote file service for safe storage. And as always we'll get hands on, and configure all of this in our lab.

System Logging and Trace Files
Hello, and welcome to this module of the Juniper Network's JNCIA Junos configuration basics course. In this module, we examine the different types of system logs that are generated on a Juniper device and how to access them. We'll also look at how we enable traceoptions to help troubleshoot problems on a network. Let's run through what you'll lean in this module. Firstly we'll talk about system logging or syslog. We'll look at how it works, what we can use it for, and how to configure Junos to help us get the most out of this feature. Then we'll learn about trace files. You can think of these as being similar to debugging on other vendors' network gear. We'll talk about how it works and how to configure it. Finally we'll take a look at how to work with the files that both syslog and traceoptions produce. We'll look at how to view the contents, monitor them in real time, and also how to manage them. And as always, we'll get hands on and configure all of this in our lab.
