Junos Enterprise Switching (JEX) Course Overview

Junos Enterprise Switching (JEX) Course Overview

The Junos Enterprise Switching (JEX) course is a comprehensive training program designed for network professionals looking to deepen their understanding of network infrastructure based on Juniper Networks' high-performance switching solutions. It covers a range of topics essential for the design and management of modern enterprise networks.

Chapter 1 introduces participants to the course structure and sets expectations. Chapter 2 delves into Layer 2 switching, including Ethernet bridging, terminology, and key design considerations. It also provides practical guidance on enabling and monitoring Layer 2 operations.

Chapter 3 focuses on virtual networks, detailing VLANs, voice VLANs, native VLANs, and the setup of routed VLAN interfaces. Chapter 4 addresses Spanning Tree Protocol (STP) and its variants, offering insights into their configuration and crucial protection mechanisms.

In Chapter 5, the course explores port security features such as MAC limiting and DHCP Snooping, while Chapter 6 looks at device security, storm control, and firewall filters. Chapter 7 introduces Virtual Chassis technology, explaining its configuration and monitoring.

Chapter 8 is dedicated to high availability features, discussing link aggregation and redundant trunk groups. Finally, the appendices (Chapters 9 and 10) offer additional resources on Ethernet Ring Protection Switching and Multiple Spanning Tree Protocol.

Overall, the JEX course equips learners with the knowledge to implement and troubleshoot Junos-based switches, enhancing network reliability, security, and performance.

Course Prerequisites

To successfully undertake the Junos Enterprise Switching (JEX) course, students should meet the following minimum prerequisites:


  • Basic understanding of networking concepts and protocols
  • Familiarity with the OSI model and the function of Layer 2 (Data Link Layer)
  • Knowledge of the basic concepts of routing and switching
  • Experience with the TCP/IP protocol suite
  • Familiarity with Ethernet and TCP/IP networking
  • Basic operating skills for the Juniper Networks Junos OS, which can be obtained through the "Introduction to the Junos Operating System (IJOS)" course or equivalent working experience
