About this course

Course Overview

This five-day course provides students with Junos platform automation knowledge through hands-on development. Students receive hands-on experience with tools and languages relevant to the Junos OS platform. The course includes an introduction to the Junos XML API, YANG and NETCONF. The course focuses on using Python and the PyEZ library to create commit scripts, operation (op) scripts, and event scripts. It also covers an introduction to automation/DevOps tools using Ansible. Finally the course discuses the use of Autoinstallation and JSNAPy automation tools. Through demonstrations and hands-on labs, students will gain experience in automating the Junos operating system and device operations.

 

This course is based on the Junos OS Release 16.2R1.

 

 

 

Target Audience

This course benefits individuals responsible for configuring and monitoring devices running the Junos OS.
