Data Center Bridging (DCB) | 79
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.
