Duration: 5 Days
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.
What You Will Learn
- 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
