Sample DCB Conguration

The following shows examples of using PFC and ETS to manage your data center trac.

In the following example:

• Incoming SAN trac is congured for priority-based ow control.

• Outbound LAN, IPC, and SAN trac is mapped into three ETS priority groups and congured for enhanced trac selection (bandwidth

allocation and scheduling).

• One lossless queue is used.
