• 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.
