Implementing Cisco Quality of Service v2.2 (QoS)

5-day Hands - on Course

Course Description

This Authorized Cisco 5-day course gives you the knowledge and skills required to design, implement, and troubleshoot Quality of Service (QoS) on a network. The course addresses the essential QoS technologies and applications for both Service Provider and Enterprise networks. Successful implementation of the techniques taught in this course will have a dramatic impact on critical network application performance

Course Objective

After completing this course the student will learn about:

• Building blocks of IP QOS
• Configure AutoQoS on WAN routers and on Catalyst access switches and monitor the results
• Configure FIFO and WFQ queuing on WAN routers and measure and analyze network performance
• Configure WRED on WAN routers to control which traffic is dropped during congestion
• Configure CBWFQ and LLQ on WAN routers to provide bandwidth and latency guarantees
• Configure COS-to-queue mapping and WRR queuing on the Catalyst 2950 switch

Intended Audience

Network professionals interested in deploying state-of-the-art QoS techniques to support multimedia traffic would benefit from this course

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.
