In this course, you’ll learn about the different methods and procedures for monitoring and maintaining Junos devices. When you’re finished with this course, you will have taken another step towards gaining Juniper Networks JNCIA-Junos certification.

This course is the fifth in a complete series covering the Juniper Networks JNCIA-Junos certification track. In this course, Juniper Networks JNCIA-Junos: 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. Finally, you will 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 are finished with this course, you will have taken another step towards gaining Juniper Networks JNCIA-Junos certification.
