Preparing the Adapter
Follow these steps to enable DCBX and specify the RoCE priority using the HII
management application. For information about the HII application, see Chapter 5
Adapter Preboot Configuration.
To prepare the adapter:
1. On the Main Configuration Page, select Data Center Bridging (DCB)
Settings, and then click Finish.
2. In the Data Center Bridging (DCB) Settings window, click the DCBX
Protocol option. The 41xxx Series Adapter supports both CEE and IEEE
protocols. This value should match the corresponding value on the DCB
switch. In this example, select CEE or Dynamic.
3. In the RoCE Priority box, type a priority value. This value should match the
corresponding value on the DCB switch. In this example, type 5. Typically, 0
is used for the default lossy traffic class, 3 is used for the FCoE traffic class,
and 4 is used for lossless iSCSI-TLV over DCB traffic class.
4. Click Back.
5. When prompted, click Yes to save the changes. Changes will take effect
after a system reset.
For Windows, you can configure DCBX using the HII or QoS method. The
configuration shown in this section is through HII. For QoS, refer to
“Configuring QoS for RoCE” on page 259.
