Sample DCB Configuration
The following shows examples of using PFC and ETS to manage your data center traffic.
In the following example:
• 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.
