Junos Class of Service (JCOS)

 

Course Content

This two-day course provides you with advanced class-of-service (CoS) knowledge and configuration examples. You will begin with an overview of CoS, then learn about classification, policing, scheduling and rewriting. The course then covers class-based forwarding and finishes with a case study. Through demonstrations and hands-on labs, you will gain experience in configuring and monitoring the JUNOS Software and monitoring basic device operations.

Certification: JNCIP-SP - JN0-661

Who should attend

This course benefits individuals responsible for configuring and monitoring devices running the Junos OS, especially those in a service provider environment. It also benefits individuals responsible for designing networks containing devices running the Junos OS.

Certifications

Prerequisites

You should attend the Introduction to the Operating System (IJOS), !JP-JRE, and JUNOS Intermediate Routing (JIR) courses, or have equivalent experience prior to attending this class. General knowledge of Protocol Independent Multicast-Sparse Mode (PIM-SM) protocol would be helpful.

Course Objectives

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

  • Understand the history and evolution of CoS.
  • Identify the CoS fields in various packet headers.
  • List the CoS processing stages on devices running the Junos OS.
  • Identify the default CoS settings on devices running the Junos OS.
  • Configure and verify behavior aggregate (BA) and multifield (MF) classification.
  • Configure and verify two-color and tricolor marking policers.
  • Configure and verify schedulers and their components.
  • Configure and verify the multiple levels of hierarchical schedulers.
  • Configure and verify packet header rewriting.
  • Configure and verify class-based forwarding.
  • Create a CoS configuration based on a set of design requirements.
