Example: PFC and ETS Operation
This section contains examples of DCB input and output policies applied on an interface.
In the example shown in Figure 6-16 for an Aggregator:
• Incoming SAN traffic is configured for priority-based flow control.
• Outbound LAN, IPC, and SAN traffic is mapped into three ETS priority groups and configured for
enhanced traffic selection (bandwidth allocation and scheduling).
• One lossless queue is used.
