Cisco Switching: Quality of Service (QoS) Fundamentals and Implementation

Learn about Quality of Service (QoS) in Cisco switching through this comprehensive 38-minute video lecture. Explore key concepts including base rates, bandwidth calculation, Power over Ethernet, and design practices for network optimization. Delve into crucial QoS topics such as delay, jitter, packet loss, IntServ, and DiffServ methodologies. Examine various queuing methods, congestion avoidance techniques like RED and WRED, and the implementation of Modular QoS. Gain practical insights into configuring Class Maps, Policy Maps, and applying QoS policies. Understand advanced concepts such as Priority Queuing, Custom Queuing, WRRQ, and Remote SPAN. Access the associated network simulator for hands-on practice and reinforce your understanding of Cisco switching and QoS principles.
