Prerequisites

Delegates are required to meet the following prerequisites:

• Completion of Interconnecting Cisco Networking Devices (ICND) or Cisco Certified Networking Associate (CCNA). The Configuring BGP on Cisco Routers course (BGP) or equivalent is recommended because some BGP background is assumed for the QoS course.

Who should attend?

This course is aimed at network designers and engineers responsible for implementation and management of IP QOS and students seeking Cisco CCIP and CCVP Certification.

What you will learn

The curriculum covers the theory of IP QoS, design issues, and configuration of various QoS mechanisms to facilitate the creation of effective administrative policies providing QoS. Case studies and lab exercises included in the course help students to apply the concepts mastered in individual modules to real-life scenarios.
The course also gives students design and usage rules for various advanced IP QoS features and the integration of IP QoS with underlying Layer 2 QoS mechanisms, allowing them to design and implement efficient, optimized, and trouble-free multi-service networks.

After completing this course, the student should be able to:

• Explain the need to implement QOS and explain methods for implementing and managing QOS
• Identify and describe different models used for ensuring QOS in a network and explain key IP QOS mechanisms used to implement these models
• Explain the use of MQC and AutoQOS to implement QOS
• Classify and Mark traffic to implement QOS a Policy
• Use Cisco queuing mechanisms to manage network congestion
• Use Cisco QoS traffic policing and traffic shaping mechanisms to effectively limit the rate of network traffic, addressing, service, and user information.
• Configure hardware maintenance chores on MARS appliance.
