Beskrivelse

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 12.3R3.4.
Through demonstrations and hands-on labs, students will gain experience in configuring and verifying Junos CoS features.


Junos Class of Service is an advanced level course.

 

Forudsætninger

Students should attend 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.
