Implementing Cisco Quality of Service v2.2

Implementing Cisco Quality of Service (QOS) v2.2 provides learners with in-depth knowledge of quality of service (QoS) requirements, conceptual models such as Best Effort, Integrated Services (IntServ) and Differentiated Services (DiffServ), and the implementation of QoS on Cisco IOS platforms. The curriculum covers the theory of 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 learners to apply the concepts mastered in individual modules to real-life scenarios. The course also gives learners design and usage rules for various advanced QoS features and the integration of QoS with underlying Layer 2 QoS mechanisms. This gives learners the opportunity to design and implement efficient, optimal, and trouble-free multiservice networks.


Upon finishing this course, you will be able to:
Explain the need to implement Quality of Service (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 the models
  • Explain the use of Modular QoS Command Line Interface (CLI) [MQC] and AutoQoS to implement QoS on the network
  • Use Cisco QoS queuing mechanisms to manage network congestion
  • Use Cisco QoS congestion avoidance mechanisms to reduce the effects of congestion on the network
  • Use Cisco QoS traffic policing and traffic shaping mechanisms to effectively limit the rate of network traffic
  • Successfully use Cisco link efficiency mechanisms to improve the bandwidth efficiency of the link
  • Correctly select the most appropriate QoS mechanisms for providing QoS using Cisco best practices


The QoS course is of utmost importance for all engineers that need advanced knowledge of IP Quality of Service mechanisms for implementation in either large enterprise or Internet Service Provider networks.


The primary audience for this course is as follows:

  • Pre- and post-sales technical engineers responsible for designing, implementing, or troubleshooting networks
  • Network architects responsible for designing multiservice networks to carry voice, video, and data traffic in an enterprise or service provider environment
  • CCIP candidates
    The secondary audience for this course comprises the CCIE Routing and Switching candidates as well as CCIE Service Provider candidates.

Prerequisite Knowledge

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.
