QOS v2.3

QOS - Implementing Cisco Quality of Service

This course gives you the knowledge and skills required to design, implement, and troubleshoot Quality of Service (QoS) on a network. You will address 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.

This alternative to traditional instructor-led training provides you with live virtual instructor-led training with the option of self-paced e-Learning. Instead of meeting in one physical locale, you will participate in live lectures over the Internet.

These e-Learning classes are taught in two three-hour lectures each week. Lectures are team taught, providing pace, diversity, and spontaneity not possible with a lone instructor. Recorded versions of lectures are available 24x7 for review if you miss any of the scheduled live lectures or if you simply prefer self-paced e-Learning to work through on your own time.

As part of Cisco's recent announcement for the CCNP Voice certification program, QOS is no longer a requirement. However, it is still part of the CCIP certification as well as several Specializations.

What You'll 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

Who Needs to Attend
