AH0054602-00 J
CEE
enables the legacy Converged Enhanced Ethernet (CEE)
protocol DCBX mode on this port.
IEEE
enables the IEEE DCBX protocol on this port.
Dynamic
enables dynamic application of either the CEE or IEEE
protocol to match the attached link partner.

On the Data Center Bridging (DCB) Settings page, enter the
RoCE v1
Priority
as a value from
0–7
. This setting indicates the DCB traffic class
priority number used for RoCE traffic and should match the number used by
the DCB-enabled switching network for RoCE traffic.
0
specifies the usual priority number used by the lossy default or
common traffic class.
3
specifies the priority number used by lossless FCoE traffic.
4
specifies the priority number used by lossless iSCSI-TLV over DCB
traffic.

,
2
,
5
,
6
, and
7
specify DCB traffic class priority numbers available for
RoCE use. Follow the respective OS RoCE setup instructions for using
this RoCE control.

NOTE
When DCBX is enabled, the adapter periodically sends link layer discovery
protocol (LLDP) packets with a dedicated unicast address that serves as the
source MAC address. This LLDP MAC address is different from the
factory-assigned adapter Ethernet MAC address. If you examine the MAC
address table for the switch port that is connected to the adapter, you will
see two MAC addresses: one for LLDP packets and one for the adapter
Ethernet interface.
