    Course Details


    This two-day course is designed to provide students with detailed coverage of the QFabric system components, design, and architecture. Students will learn about the tools available for troubleshooting the system and will be provided examples of how those tools are used. Through demonstrations and hands-on labs, students will gain knowledge of detailed system operations and experience troubleshooting the QFabric system.


    This course is intended to prepare individuals for typical troubleshooting issues they would meet in the field. It assumes that the deepest level of system troubleshooting will continue to be provided by the Juniper Networks Technical Assistance Center (JTAC).


    This course uses the Juniper Networks QFX3000-M system for the hands-on component. This course is based on the Junos operating system Release 13.2X52-D10.5.
