Cisco 360 Learning Program for CCIE R&S - Lesson Cisco Catalyst QoS

Mastering Catalyst 3550 and Catalyst 3560 Quality of Service is vital for delay sensitive applications such as voice, video and multicast. The material covered will help you build confidence and knowledge required for this topic in a CCIE® lab.

This self-paced Lesson Module provides a set of two complementary learning resources:

• One and one half hours of video on demand instruction on Catalyst QoS
• Supplementary "Spot-the-Issues" soft assessment quizzes

The centerpiece of this Lesson Module is the Catalyst QoS video on demand instruction. The following split screen format of each Video on Demand module provides the powerful learning experience of looking over a CCIE's shoulder while he both configures and explains the operation of Catalyst QoS:

In the context of the Cisco 360 Three Phase CCIE Lab Preparation Roadmap, this Catalyst QoS Lesson Module is recommended to be used during Phase Two of this Roadmap.

You will download all content for this Lesson Module on your own computer. Therefore, you will be able to view and access the content without being connected to the Internet. Also, it must be noted that you will need to also download the LockLizard DRM viewer in order to access the content of this Lesson Module.

Duration:

Approximately 1.5 hours of Video on Demand modules divided into five sessions. Each VoD session is approximately 15 minutes in length. For each block, a set of supporting "Spot the Issues" Soft Assessment Quizzes are provided.

Target Audience

This self-paced Lesson Module is for technical professionals who need to master CCIE level problems involving Catalyst QoS that involve:

• Catalyst 3560 QoS Trust and Marking Issues
• Catalyst 3560 Policing
• Shaped and Shared Round Robin Queuing with the Catalyst 3560

Lesson Module Objectives

Upon completion of this self-paced Lesson Module, you should be able to formulate well defined mental simulations to perform the following Catalyst QoS tasks with the customary minimally described parameters commonly found in CCIE Level tasks.

• Formulate an End-to-End Opening Moves Strategy for Catalyst QoS Topic
• Learning Catalyst 3560 Differentiated Services Edge Operations: Trust, Mark and Police
• Learning Catalyst 3560 Differentiated Services Internal Operations: Queue and WTD

Lesson Module Prerequisites

Following are the prerequisites for using this Lesson Module

• The ability to perform the configuration basics to implement Catalyst QoS
• The basics of the Differentiated Services QoS Model

To view the contents of this Lesson Module, download the LockLizard DRM viewer to be able to view the VoD modules.
