This four-day course is designed to provide students with Junos platform automation knowledge through hands-on development. Students receive hands-on experience with tools and languages relevant to Junos platforms. The course includes an overview of Extensible Markup Language (XML), Stylesheet Language Alternative Syntax (SLAX), the Junos template and function library, commit scripts, operation (op) scripts, and event scripts. It also covers an introduction to the Python and Ruby languages as well as automation/DevOps tools such as PyEZ, RubyEZ, Puppet, and Ansible. 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 14.2R2.6.

After successfully completing this course, you should be able to:

• Describe the benefits of using Junos OS automation.
• Describe the differences between commit, op, and event scripts.

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

Students should have intermediate-level networking knowledge and an understanding of the Open Systems Interconnection (OSI) model and the TCP/IP protocol suite. Students should also have familiarity with a programming language such as C, C++, Perl, Python, Ruby, or Java. Students should also attend the Introduction to the Junos Operating System (IJOS) course prior to attending this class. Lastly, a high level understanding of object-oriented programming is a plus, but not a requirement.
