Material Presentation for Catalyst Switching Platforms
Figure 3-1 shows the general QoS packet-flow architecture for Cisco Catalyst switches. The
architecture presents only the standard model for QoS features on each Catalyst platform.

For each Catalyst platform, this book discusses QoS features using the following flowchart:
• QoS Architecture Overview
• Input Scheduling
• Classification and Marking
• Policing
• Congestion Management and Avoidance
• Sample Configurations ...
