This course gives the knowledge and skills required to design, implement, and troubleshoot Quality of Service (QoS) on a network. It combines the key elements of the previous DQoS v1.0 and QoS v1.0 Cisco courses, to address the essential QoS technologies and applications for both Service Provider and Enterprise networks.

You will learn:

• The building blocks of IP QOS
• To configure AutoQoS on WAN routers and on Catalyst access switches and monitor the results
• To configure FIFO and WFQ queuing on WAN routers and measure and analyze network performance
• To configure CBWFQ and LLQ on WAN routers to provide bandwidth and latency guarantees
• To configure COS-to-que ue mapping and WRR queuing on the Catalyst 2950 switch
