Installation Check
To verify the correct installation of the driver and to ensure that the host port is
seen by the switch, follow the procedure below.
To verify the correct installation of the driver
1.
Verify the host port shows up in the switch FLOGI database using the
show
flogi database
command for the case of a Cisco
®
FCF and f
coe
-loginshow
command for the case of a Brocade
®
FCF.
2.
If the Host WWPN does not appear in the FLOGI database, then provide
driver log messages for review.
Limitations
NPIV is not currently supported with this release on ESXi, due to lack of
supporting inbox components.
Non-offload FCoE is not supported with offload-capable QLogic devices.
Only the full hardware offload path is supported.

Driver
Description
bnx2x
This driver manages all PCI device resources (registers, host inter-
face queues) and also acts as the Layer 2 VMware low-level net-
work driver for QLogic's 8400/3400 Series 10G device. This driver
directly controls the hardware and is responsible for sending and
receiving Ethernet packets on behalf of the VMware host networking
stack. The bnx2x driver also receives and processes device inter-
rupts, both on behalf of itself (for L2 networking) and on behalf of the
bnx2fc (FCoE protocol) and CNIC drivers.
bnx2fc
The QLogic VMware FCoE driver is a kernel mode driver used to
provide a translation layer between the VMware SCSI stack and the
QLogic FCoE firmware/hardware. In addition, the driver interfaces
with the networking layer to transmit and receive encapsulated
FCoE frames on behalf of open-fcoe's
libfc/libfcoe
for
FIP/device discovery.
