Presentation
Developed by Juniper Networks, Junos OS stands out for the quality and speed of its networking services. This course provides the knowledge and skills to deploy and configure EX-Series switches in an enterprise environment.
Objectives
This course develops your expertise in switching and configuration with Junos Enhanced Layer 2 Software in an enterprise environment. You will explore switching, virtual LANs (VLANs), Spanning Tree Protocol (STP), security and high availability. The course combines theory and hands-on labs to develop your ability to configure and monitor Junos OS and the associated equipment.
By the end of the course, you will be able to:
- Understand the benefits of implementing switched LANs.
- Describe transparent bridging concepts and operations.
