Using OCCFG for Windows NIC Driver Options
The occfg.exe program supports configuring parameters for the network functions on
Emulex Ethernet adapters either through interactive mode with a set of menus, or
command line mode that is scriptable.
If you performed a standard driver installation, the occfg.exe is located in the following
directory:
Directory of C:\Program Files\Emulex\AutoPilot
Installer\NIC\Drivers\NDIS\<platform>\<OS>
The following section describes how to use the occfg.exe program to configure the
Windows device driver from the command line.

Running with no arguments will display a menu to select the adapter and
parameters to modify. Using the command line arguments allow scripting
this process.
CRC Errors The number of packets dropped as the result of CRC errors on the
layer 2 Ethernet packet. In products that expose multiple PCIe
functions per Ethernet port, this statistic is only incremented for
the lowest PCI function per port since the packet cannot be
further classified because of the error.
Receive IP Checksum Errors The number of receive packets with an incorrect IPv4 checksum.
These packets are provided to the TCP/IP stack for disposal in the
operating system.
Receive UDP Checksum Errors The number of receive packets with an incorrect UDP checksum.
These packets are provided to the TCP/IP stack for disposal in the
operating system.
Receive TCP Errors The number of receive packets with an incorrect TCP checksum.
These packets are provided to the TCP/IP stack for disposal in the
operating system.
Tunnels allocated Number of interfaces converted to tunnel interfaces. Used with
NVGRE offload enabled and on.
Tenants allocated Number of interfaces converted into tenant interfaces. Used with
NVGRE offload enabled and on and VMQ.
Virtual Functions allocated Number of PCIe virtual functions created by the SR-IOV supporting
adapter.
