OFED and RDMA applications that depend on libibverbs also require the
QLogic RDMA user space library, libqedr. Install libqedr using the libqedr
RPM or source packages.
RoCE supports only little endian.
RoCE does not work over a VF in an SR-IOV environment.
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
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 41
xxx
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 245
