Implementing Cisco Quality Of Service

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.

  • 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

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

Initial router and switch configuration; familiarization with the lab environment.

Lab 2: Baseline QoS Measurement
Network performance testing with and without application traffic loads.

Lab 3: Classification and Marking Using MQC
Configure MQC classification using ACLs. Configure and monitor Class-Based Marking.

Lab 4: Classification Using NBAR
Configure NBAR protocol discovery. Configure MQC Classification via NBAR.

Lab 5: LAN-Based Packet Classification and Marking
Configure Catalyst trust boundaries and COS-to-DSCP mapping. Configure MQC classification and marking on Catalyst switch.

Lab 6: Configuring QoS Pre-Classify
Configure QoS pre-classify on a router using a GRE tunnel. Monitor the operation of QoS pre-classification.

Lab 7: Configuring Basic Queuing
Configure FIFO queuing on WAN routers. Configure WFQ queuing on WAN routers. Measure and analyze network performance.
