Description

This course is the fifth in a complete series covering the Juniper Networks JNCIA-Junos certification track, providing you with the skills and knowledge required to pass the JN0-102 exam. In this course, Juniper Networks JNCIA-Junos (JN0-102): Operational Monitoring and Maintenance, you will first learn how to monitor the Juniper system and chassis status with the CLI regardless of the hardware platform. Then, you will move on to monitoring interfaces using the ‘monitor interface’ command. This is a really powerful command that allows you to monitor interface statistics and traffic in real-time. After that, you will look at the network troubleshooting tools - ping and traceroute. You are probably familiar with these already, but you’ll take a look at some options you have from within Junos to extend their functionality and you’ll learn about a couple of the network utilities that are also built into Junos - namely telnet and SSH clients. Finally, you’ll look at steps involved in the process of recovering the root password. As with all the courses in this series, there will be plenty of time spent on the command line demonstrating all the commands covered to cement your knowledge. When you’re finished with this course, you will have taken another step towards gaining Juniper Networks JNCIA-Junos certification.

Course Overview
Hi everyone. My name is Rich Bibby and welcome to my course, Juniper Networks JNCIA-Junos: Operational Monitoring and Maintenance. I'm a network engineer based in Manchester in the UK. This is the fifth course in a complete series, covering the Juniper Network's JNCIA-Junos certification track, providing the viewer with the skills and knowledge required to pass the JN0-102 exam. In this course, you'll learn about the different methods and procedures for monitoring and maintaining Junos devices. Some of the major topics that we will cover include how to monitor the system and the chasis from the CLI, commands to view interface statistics and errors, how to access and use the built-in network tools and utilities like ping, trace-root, telnet and SSH, monitoring traffic in real time and capturing raw data packets as they pass through network interfaces, how to operate the Junos OS, and how to recover the root user password. When you're finished with the course, you'll have taken another step towards gaining Juniper Networks JNCIA-Junos certification, one of the most sought-after in the industry. I hope you'll join me on this journey to learn how to monitor and maintain your Juniper Network devices with the Juniper Networks JNCIA-Junos Operational Monitoring and Maintenance course at Pluralsight.

Monitoring the System and Chassis
Hello and welcome to the first module of the Juniper Networks JNCIA- Junos: Operational Monitoring and Maintenance course. Hopefully if you're viewing this course, you'll probably already have taken the previous courses in this series. And if so, then you're probably aware of the different options we have available when it comes to monitoring Junos devices. The primary option for monitoring Junos devices is the Command Line Interface or CLI and this will be the focus of this module. Another option for monitoring is the J-Web interface, and as you've already seen, this is a rich, graphical user interface for managing Junos. As we've also covered in a previous course, we can make use of the SNMP protocol, along with system logging and trace options in order to view information about the status of our system and how it's performing. And lastly, depending on the hardware platform, Junos devices have LEDs and LCD displays that can also provide us with useful information. As I said, Juniper considers the primary operational monitoring tool for Junos to be the CLI, and this will be our focus. So, let's run through what you'll learn in this module. Firstly, we'll talk about monitoring the system status with the CLI and look at the different types of information you can monitor from here. Then we'll move on to monitoring the status of the chassis using the CLI, and again we'll look at the kinds of information that you can extract from here that's useful to you as a network engineer.

Monitoring Network Interfaces
Hello and welcome to this module of the Juniper Network's JNCIA, Junos Operational Monitoring and Maintenance Course. Hopefully, if you're viewing this course you'll have already taken the previous courses in the series and if so, then you're probably aware of some of the different options we have available when it comes to monitoring Junos devices. The primary option for monitoring Junos devices is the command line interface or CLI. This will be the focus of this module. Specifically in relation to monitoring the status and performance of network interfaces. Let's run through what you'll learn in this module. Firstly, we'll look at how to monitor the status of interfaces from the CLI using the "show interfaces" command. This is a powerful command that allows you to verify various aspects of the status of your interfaces. Then we'll move on to monitoring interfaces using their monitor interface command. Again, this is a really powerful command that allows you to monitor interface statistics and traffic in real-time.

Network Tools – Ping, Traceroute, Telnet, and SSH
Hello and welcome to this module of the Juniper Networks JNCIA-Junos Operational Monitoring and Maintenance course. In this module, you'll learn all about some of the network tools and utilities that are built into Junos. Let's run through what you'll learn in this module. Firstly, we'll look at the network troubleshooting tools, ping and trace route. You're probably familiar with these already, but we'll take a look at some of the options you have from within Junos to extend the functionality of these ubiquitous troubleshooting tools. Then you'll learn about a couple of the network utilities that are also built into Junos, namely telnet and SSH clients. These are used to connect to remote hosts, which could be other network devices or any other devices acting as servers for these two standard network protocols, and as always, we'll get hands on and try out all of this in our lab.

Real-time Traffic Monitoring
Hello and welcome to this module of the Juniper Network's JNCIA, Junos Operational Monitoring and Maintenance Course. Sometimes it's necessary to monitor the performance of your Juniper device in real-time. For example, capturing the actual data packets passing through an interface in order to help fix a network issue. This module looks at how to do this in Junos. So, lets run through what you'll learn in this module. Firstly, we will talk about how and why you would monitor traffic in real time. We'll talk about the types of traffic that you can monitor and what you can do with the output that the monitored traffic command produces. Then we'll get our hands dirty once again and explore how to use this powerful feature of Junos from the CLI of our lab switch.

Junos OS Installation and Software Upgrades
Hello, and welcome to this module of the Juniper Network's JNCIA Junos Operational Monitoring and Maintenance course. It's important to ensure that any network device is running current and supported versions of the operating system. This module looks at how to determine the version of Junos that your device is currently using, and how to upgrade it if required. So, let's run through what you'll learn in this module. Firstly, we'll look at how to identify the current Junos software release that is running on your Juniper device. And we'll also look at how to identify some of the packages and processes that are included as part of the Junos software release. Then you'll learn how to understand the naming convention used for the software releases, and how to download the release that you need for your hardware platform. And then we'll look at the process and the commands required to upgrade Junos on a device, and finally, in our lab, we'll step through the actual process of upgrading the Junos version on our SRX220.

Root Password Recovery
Hello and welcome to this module of the Juniper Networks JNCIA-Junos Operational Monitoring and Maintenance course. In this module, you'll learn how to recover the root password on a Junos device. You may need to do this if you are unable to log into a device, for example, if you have forgotten your password or if you need to configure a device that you've never had access to previously. So, let's run through what you'll learn in this module. Firstly, we'll look at the steps involved in the process of recovering the root password. It's a very simple process and certainly one that may come in handy to know at some point when managing Juniper network gear. Then we'll get our hands on the lab gear once more and use the process to recover the root password on our lab EX-2200 series Switch so you can see the whole process in action.
