Introduction to JUNOS Software (IJS)

Course Overview

This one-day course provides students with the foundational knowledge required to work with JUNOS Software and to configure devices running JUNOS Software. Key topics include user interface options with a heavy focus on the command-line interface (CLI), configuration tasks typically associated with the initial setup of devices, interface configuration basics with configuration examples, secondary system configuration, and the basics of operational monitoring and maintenance of devices running JUNOS Software. This course is based on JUNOS Software version 9.6R1.13.

Through demonstrations and hands-on labs, students will gain experience in configuring and monitoring the JUNOS Software and monitoring basic device operations.

Objectives

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

• Describe the basic design architecture of JUNOS Software;
• Identify and provide a brief overview of devices running JUNOS Software;
• Navigate within the JUNOS Software CLI;
• Perform tasks within the CLI operational and configuration modes;
• Restore a device running JUNOS Software to its factory-default state;
• Perform initial configuration tasks;
• Configure and monitor network interfaces;
• Describe user configuration and authentication options;
• Perform secondary configuration tasks for features and services such as syslog and tracing, Network Time Protocol (NTP), configuration archival, and SNMP;
• Monitor basic operation for JUNOS Software and devices;
• Identify and use network utilities;
• Upgrade the JUNOS Software; and
• Perform file system maintenance and password recovery on a device running JUNOS Software.
