2. Software/Driver Loading

Before proceeding, please ensure that Unified Wire Installer is installed with DCB support as
mentioned in CLI mode (individual drivers)
Network (cxgb4; t4_tom for full offload support) and FCoE Initiator (csiostor) drivers must be
loaded in order to enable DCB feature. Also, the drivers must be loaded by the root user. Any
attempt to load the drivers as a regular user will fail. Run the following commands:
[root@host]# modprobe cxgb4
[root@host]# modprobe t4_tom
[root@host]# modprobe csiostor
Once the storage and networking traffic are started simultaneously, they will honor DCB settings
defined on the switch.
Limited QA performed for IEEE version of DCBX.
