Kursbeschreibung Kurstermine


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.


This is an advanced level course. Students should have attended:

  • the Introduction to the Junos Operating System (IJOS) course
  • the Junos Routing Essentials (JRE) course
  • and the Junos Intermediate Routing (JIR) course, or Have equivalent experience prior to attending this class.
  • General knowledge of CoS concepts is also helpful.


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.


This two-day course provides students with advanced class-of-service (CoS) knowledge and configuration examples. The course begins with an overview of CoS before going into classification, policing, scheduling, and rewriting. The course then covers class-based forwarding and finishes with a case study. This course is based on the Junos operating system Release 10.3R1.9.

Through demonstrations and hands-on labs, students will gain experience in configuring and verifying Junos CoS features.
