Description
Implementing Cisco QoS 2.2 provides students with in-depth knowledge of IP QoS requirements, conceptual models such as Best Effort (over provisioning), Integrated Services (IntServ) and Differentiated Services (DiffServ), and the implementation of IP QoS on Cisco IOS platforms. This course 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 multiservice networks.

Skills Taught
After completing this course, the student should 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 MQC and AutoQoS to implement QoS on the network
  • Classify and mark network traffic to implement a policy defining QoS requirements
  • 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
  • Use Cisco link efficiency mechanisms to improve the bandwidth efficiency of a low speed WAN link
  • Correctly select the most appropriate QoS mechanisms for providing QoS using Cisco “best practices” in service provider and enterprise networks

Audience
Implementing Cisco QoS is recommended training for individuals seeking certification as a Cisco Certified Internet Professional (CCIP), IP Telephony Cisco Qualified Specialist (CQS), and IP Telephony Channels Specialization for organizations. This course is also recommended for any individual needing to design and/or implement QoS mechanisms in today’s mission critical Cisco networks. Additionally, CCIE candidates (R/S, Security, or Voice) can use this course to prepare themselves for any QoS objectives in their lab exam.

Prerequisites
Students should complete the Interconnecting Cisco Networking Devices (ICND) course and the acquisition if the Cisco Certified Network Associate (CCNA) certification is recommended. If students have not completed this course and certification, they should possess the equivalent knowledge.
