Data Center Switching (DCX)
This course benefits individuals responsible for configuring and monitoring switching features that exist on the Junos OS running on the QFX5100 and EX4300 Series platforms, including individuals in professional services, sales and support organizations, and the end users.
The following are the prerequisites for this course:
- Understanding of the OSI model;
- Junos OS configuration experience—the Introduction to the Junos Operating System (IJOS) course or equivalent;
- Intermediate routing knowledge—the Junos Routing Essentials (JRE) course or equivalent; and
- Intermediate switching knowledge - the Junos Enterprise Switching using Enhanced Layer 2 Software (JEX-ELS) course or equivalent.
After successfully completing this course, you should be able to:
- Identify current challenges in today’s data center environments and explain how the QFX5100 system solves some of those challenges.
- List the various components of the QFX5100 system and explain their roles and responsibilities.
- Gain knowledge and understanding of the control plane and data plane of the QFX5100.
- Explain the purpose and value of ZTP.
- Describe the components and operations of ZTP.
- Deploy a QFX5100 Series switch using ZTP.
- Explain the purpose and value of ISSU.
- Describe the components and operations of ISSU.
- Upgrade a QFX5100 Series switch using ISSU.
- Describe the various topologies that can be created using MC-LAG.
- Describe the MC-LAG states.
- Configure and monitor MC-LAG.
- Describe key concepts and components of a mixed Virtual Chassis.
- Explain the operational details of a mixed Virtual Chassis.
- Implement a mixed Virtual Chassis and verify its operations.
- Describe key concepts and components of a Virtual Chassis Fabric.
- Describe the control and forwarding plane of a Virtual Chassis Fabric.
- Describe the software requirements and upgrade procedure of Virtual Chassis Fabric.
- Describe how to use the CLI to configure and monitor a Virtual Chassis Fabric.
- Describe how to provision a Virtual Chassis Fabric using nonprovisioning, preprovisioning, and autoprovisioning.
- Describe how to manage a Virtual Chassis Fabric with Junos Space.
This two-day course is designed to introduce the features introduced by the QFX5100 and EX4300 Series Ethernet Switches including, but not limited to, Zero Touch Provisioning (ZTP), unified in-service software upgrade (ISSU), multichassis link aggregation (MC-LAG), Mixed Virtual Fabric, and Virtual Chassis Fabric (VCF). Students will learn to configure and monitor these features that exist on the Junos operating system running on the QFX5100 and EX4300 Series platform. Through demonstrations and hands-on labs, students will gain experience configuring, monitoring, and analyzing the above features of the Junos OS. This course is based on Junos OS Release 12.3.
