  features are no longer supported
- The prefix for Intel(R) PROSet for Windows* Device Manager ANS teams has
  changed from "TEAM : " to "TEAM: ". Please update your scripts accordingly.


Configuring SR-IOV for improved network security
================================================

In a virtualized environment, on Intel(R) Server Adapters that support SR-IOV,
the virtual function (VF) may be subject to malicious behavior. Software-
generated frames are not expected and can throttle traffic between the host
and the virtual switch, reducing performance. To resolve this issue, configure
all SR-IOV enabled ports for VLAN tagging. This configuration allows
unexpected, and potentially malicious, frames to be dropped.


Teams and VLANs are not supported on Microsoft* Windows* 10
===========================================================

Intel(R) Advanced Network Services (Intel(R) ANS) Teams and VLANs are not
supported on Microsoft* Windows* 10. Any Teams or VLANs created with
Release 20.1, 20.2 or 20.3 on a Windows 10 system will be corrupted and cannot
be upgraded to version 20.4. The version 20.4 installer will remove existing
Teams and VLANs. Team members that are not Intel devices will not be renamed
back to their original names. This is cosmetic only and does not change their
functionality. Reinstall their drivers to get the original names back.


Operating System Support
========================

The most recent software and drivers for unsupported operating systems
can be found on the Intel Customer Support website at
http://www.intel.com/support/go/network/adapter/home.htm

Some older Intel(R) Ethernet Adapters do not have full software support for
the most recent versions of Microsoft Windows*. Many older Intel Ethernet
Adapters have base drivers supplied by Microsoft Windows. Lists of supported
devices per OS are available at:
http://www.intel.com/support/go/network/adapter/nicoscomp.htm

Intel 10GbE Ethernet Adapters do not support Microsoft* Windows* 32-bit
operating systems. They support 32-bit versions of Linux* and FreeBSD*.


Installing Drivers and Intel(R) PROSet for Windows* Device Manager
==================================================================

You must have administrator rights to install or use Intel PROSet for
Windows Device Manager. Intel recommends the following procedure for installing
drivers:
1) Cancel any Found New Hardware Wizard screens that open.
2) Start the autorun located on the CD or in your download directory.
3) Click "Install Drivers and Software" and follow the instructions in the
    install wizard.

Intel(R) PROSet functionality is integrated with the Windows Device
Manager. To configure Intel(R) Ethernet Adapters and Controllers,
open the Windows Device Manager. Do not open adapter, team, or VLAN
properties from the network control panel as you may be prompted to
reboot your system.

You must upgrade PROSet when upgrading drivers. Failure to do so will
result in instability and missing tabs in Windows Device Manager.
For software and driver versions prior to Release 16.2, if you have Fibre
Channel over Ethernet (FCoE) boot enabled on any devices in the system, you
will not be able to upgrade your drivers. You must disable FCoE boot before
upgrading your ethernet drivers. This issue is resolved in Release 16.2 and
beyond.

NOTE: Support for the Intel PROSet command line utilities (prosetcl.exe and
  crashdmp.exe) has been removed. This functionality has been replaced by
  the Intel Netcmdlets for Microsoft* Windows PowerShell*. Please
   transition all of your scripts and processes to use the Intel Netcmdlets
  for Microsoft Windows PowerShell. Microsoft* Windows* 8.1 and Windows
  Server* 2012 R2 are the last operating systems to support the Intel PROSet
  command line utilities.

Intel PROSet for Windows* Device Manager is not supported on the
following devices
----------------------------------------------------------------
* Intel(R) 82552 10/100 Network Connection
* Intel(R) 82567V-3 Gigabit Network Connection
* Intel(R) X552 10G Ethernet devices
* Intel(R) X552 Virtual Function devices
* Intel(R) I218 1G Ethernet devices on systems with Intel X552 10G Ethernet
  devices

Intel PROSet fails to install
-----------------------------
A possible cause could be the Windows Modules Installer service is disabled.
The installer for Intel PROSet requires this service. You can enable this
service from the Administrative Tools -> Component Services control panel.


User Guides
===========

Several user guides for Intel Network Connections are available for
this product. You may access them in the following ways:
- On Windows-based systems, start the autorun program on the Intel CD,
  then click "View User Guides".
- Double-click "index.htm" located in the root of the Intel CD.
- Go to http://support.intel.com.

User Guide Known Issues
-----------------------
"A script on this page is causing Microsoft Internet Explorer
to run slowly" error
-------------------------------------------------------------
Upgrading to Microsoft Internet Explorer version 6 or later will resolve
this issue.


Intel Fiber Optic Adapters
==========================

Caution: The fiber optic ports may utilize Class 1 or Class 1M laser
devices. Do not stare into the end of a fiber optic connector
connected to a "live" system. Do not use optical instruments to
view the laser output. Using optical instruments increases eye hazard.
Laser radiation is hazardous and may cause eye injury. To inspect a
connector, receptacle or adapter end, be sure that the fiber optic
device or system is turned off, or the fiber cable is disconnected
from the "live" system.

The Intel Gigabit and 10GbE network adapters with fiber optic connections
operate only at their native speed and only at full-duplex. Therefore
you do not need to make any adjustments. Use of controls or
adjustments or performance of procedures other than those specified
herein may result in hazardous radiation exposure. The laser module
contains no serviceable parts.


Saving and Restoring Adapter Settings in Microsoft Windows
operating systems
==========================================================

You can save and then restore adapter settings using the Microsoft*
Windows PowerShell* script, SaveRestore.ps1. You must have Administration
privileges to run scripts. If you do not have Administration privileges,
you will not receive an error; the script just will not run. Only adapter
settings are saved (including ANS teaming and VLANs). The adapter's
driver is not saved. Restore using the script only once. Restoring multiple
times may result in unstable configuration. The Restore operation requires the
same OS as when the configuration was saved.

NOTE: Intel(R) PROSet for Windows* Device Manager must be installed for
  SaveRestore.ps1 to run. Also, for systems running a 64-bit OS, be sure
  to run the 64-bit version of Windows PowerShell, not the 32-bit (x86)
  version, when running the SaveRestore.ps1 script.

NOTE: Support for the SaveResDX.vbs script is being removed. Please transition
  all of your scripts and processes to Microsoft Windows PowerShell.

Major Operating system upgrades and saving your configuration
-------------------------------------------------------------
Your network device settings, including teams and VLANs, are not saved
when you upgrade your operating system. You must reinstall your network
drivers and software and reconfigure your network devices. This applies
for upgrading from one version of Microsoft Windows to another
(i.e., upgrading from Windows 7 to Windows 8), not applying a service
pack.


Teaming Notes
=============
Intel devices that are not supported by Intel(R) PROSet can still be added to
teams. These devices are supported by the Multi-Vendor Teaming functionality
of ANS teams.

Microsoft Server 2012 NIC Teaming (LBFO)
----------------------------------------
Intel(R) Advanced Network Services (ANS) teaming and VLANs are incompatible
with Microsoft Server 2012 NIC Teaming (LBFO). Do not create an LBFO team
using ports that are part of an ANS team or ANS VLAN.

DCB is not compatible with Microsoft Server 2012 NIC Teaming (LBFO)
-------------------------------------------------------------------
Data Center Bridging (DCB) is incompatible with Microsoft Server 2012 NIC
Teaming (LBFO). Do not create an LBFO team using Intel 10G ports when DCB is
installed. Do not install DCB if Intel 10G ports are part of an LBFO team.
Install failures and persistent link loss may occur if DCB and LBFO are used
on the same port. Installing Microsoft's Hot fix KB 2818790 will resolve the
 issue. This issue only affects Microsoft Windows Server 2012.

RLB is not supported when a team is added to a virtual NIC
----------------------------------------------------------
Virtual NICs cannot be created on a team with Receive Load Balancing enabled.
Receive Load Balancing is automatically disabled if you create a virtual NIC
on a team.

Team setup requirement
----------------------
Before creating a team, make sure each adapter is configured similarly. Check
each adapter's settings in Intel PROSet. Settings to check include QoS Packet
Tagging, Jumbo Frames, and the various offloads. If team members implement
Advanced features differently, the team will align the settings with the least
capable adapter.

Changing Offload Settings for an Adapter in an ANS Team
-------------------------------------------------------
When you disable an offload setting for an adapter in an ANS team, the team
reloads and the team capabilities are recalculated. As a result, the offload
setting is disabled for the remaining adapters in the ANS team.
Intel PROSet does not reflect the fact that the offload setting is disabled
for the remaining adapters in the team.
If you re-enable the offload setting for the original adapter in the team,
the settings will not be applied until the system is rebooted or the team
is reloaded.

IEEE 802.3ad teaming on Cisco trunks
------------------------------------
When implementing 802.3ad teams on Cisco switch ports in trunking mode,
set the native/untagged VLAN for these ports to ID 1. Otherwise, you may
experience traffic loss or lack of failover between aggregators. See your
Cisco documentation for information about setting the native VLAN ID.


Teaming Known Issues
--------------------

Unexpected performance drop or disabled ANS team member
-------------------------------------------------------
Using non-Intel cmdlets, such as the Set-NetAdapterAdvancedProperty cmdlet
provided in Microsoft PowerShell*, to change settings for an ANS-teamed
adapter may cause the team to stop using that adapter to pass traffic.
You may see this as reduced performance or the adapter being disabled
in the PROSet Teaming GUI. You can repair the issue by changing the
setting back to its previous state, or by removing the adapter from
the ANS team and then adding it back.

Network Connections window shows the team as disabled or network
cable unplugged
----------------------------------------------------------------
After adding a VLAN to the team, this is normal. The connection
protocols are now bound to the VLAN on the team. You can configure the
connection protocols in the Properties for the VLAN.

Team name doesn't change in Device Manager
------------------------------------------
If you modify a team name from the team property sheet, it may take
several minutes for the name to change in Device Manager. Closing and
opening Device Manager will load the new name.

Removing a teamed adapter from a hot-plug system
------------------------------------------------
When you physically remove an adapter that is part of a team or a VLAN,
you must reboot or reload the team/VLAN before using that adapter in the
same network. This will prevent Ethernet address conflicts.

VLANs remain after team removal
-------------------------------
When you remove a team, some of the VLANs bound to that team may remain.
You can manually remove the VLANs to correct the issue.

Changing speed and duplex of adapters in a team
-----------------------------------------------
When you add an adapter to a Link Aggregation team using Intel PROSet,
make sure that the adapter is running at the same speed and duplex of
the other adapters in the team.

Compatibility notes for Multi Vendor Teaming
--------------------------------------------
Attempting to hot-add a non-Intel adapter to a team may cause system
instability. If you do hot-add a non-Intel adapter to a team, make sure
you restart the computer or reload the team.

IEEE 802.3ad teaming with Foundry switches
------------------------------------------
Foundry switches require an even number of ports in an aggregated link. If
you remove an adapter from an 802.3ad team connected to a Foundry switch,
make sure you maintain an even number of adapters in the team.


Jumbo Frames and Jumbo Packets
==============================

Jumbo Frames and MACSec are not compatible on the Intel(R) 82579LM and
Intel(R) 82579V Network Connections. If MACSec is enabled on a platform
containing either part, you will not be able to enable Jumbo Frames on
the connection.

Limited Jumbo Frame Size
------------------------
Some Intel gigabit adapters and connections that support Jumbo Frames have a
frame size limit of 4K bytes. The following devices have this limitation:
  Intel(R) 82577LM Gigabit Network Connection
  Intel(R) 82578DM Gigabit Network Connection

The following devices do not support jumbo frames:
  Intel(R) PRO/1000 Gigabit Server Adapter
  Intel(R) PRO/1000 PM Network Connection
  Intel(R) 82562V 10/100 Network Connection
  Intel(R) 82562GT 10/100 Network Connection
  Intel(R) 82566DM Gigabit Network Connection
  Intel(R) 82566DC Gigabit Network Connection
  Intel(R) 82566DC-2 Gigabit Network Connection
  Intel(R) 82562V-2 10/100 Network Connection
  Intel(R) 82562G-2 10/100 Network Connection
  Intel(R) 82562GT-2 10/100 Network Connection
  Intel(R) 82567LF Gigabit Network Connection
  Intel(R) 82567V Gigabit Network Connection
  Intel(R) 82567LF-2 Gigabit Network Connection
  Intel(R) 82567V-2 Gigabit Network Connection
  Intel(R) 82567LF-3 Gigabit Network Connection
  Intel(R) 82552 10/100 Network Connection
  Intel(R) 82577LC Gigabit Network Connection
  Intel(R) 82578DC Gigabit Network Connection
  Intel(R) 82567V-3 Gigabit Network Connection
  Intel(R) 82567V-4 Gigabit Network Connection

The Intel PRO/1000 PL Network Connection supports jumbo frames in Microsoft*
Windows* operating systems only when Intel(R) PROSet for Windows Device
Manager is installed.


Power Management and System Wake
================================

Not all systems support every wake setting. There may be BIOS or Operating
System settings that need to be enabled for your system to wake up. In
particular, this is true for Wake from S5 (also referred to as Wake from power
 off). Microsoft Windows 7 and Windows Server 2008 R2 do not support Wake on
directed packet. Systems with these operating systems will not wake on a
ping or other directed packet.

System does not wake when expected
----------------------------------
Under Microsoft Windows 7 or Windows Server 2008 R2, the system may not wake
when sent an ARP packet. Forcing your system into Home Networking mode
(instead of work or public mode) will resolve the issue. You can set the
network mode during install or from the Networking Control Panel.
However, if the network is disconnected and reconnected, and a DHCP server
is not available or if there is no default gateway defined, it appears to
the operating system that the network is undefined and the OS will reset
it to public.

Under Microsoft Windows 8 or Windows Server 2012, the system may not wake even
though Wake on LAN settings are enabled. Disabling Fast Startup in the
operating system should resolve the issue.

System does not wake on link
----------------------------
On a driver-only installation, if you change 'Wake on Link Settings' to
Forced and change 'Wake on Magic Packet' and 'Wake on Pattern Match' to Disabled,
the system may not wake up when expected. In order to "Wake on Link"
successfully, check the Power Management tab and make sure that "Allow
this device to wake the computer" is checked. You may also need to change
'Wake on Magic Packet' or 'Wake on Pattern Match' to Enabled.
On Microsoft* Windows* 7, or later, you must enable Wake on Magic Packet or
Wake on Pattern Match for Wake on Link to function properly.

Directed Packets may not wake the system
----------------------------------------
On some systems, quad port server adapters may not wake when
configured to wake on directed packet. If you experience problems
waking on directed packets, you must configure the adapter to
use Magic Packets*.

Power Management options are unavailable or missing
---------------------------------------------------
If you install only the base drivers, later install Intel(R) PROSet for
Windows Device Manager, then remove Intel PROSet, the settings on the Power
Management tab on the Adapter Property Sheet may be unavailable or missing
altogether. You must reinstall Intel PROSet to resolve the issue.

Low power link speed slower than expected
-----------------------------------------
If you disable the "Reduce Power During Standby" setting and remove power
from the system, your system may link at 10Mbps when power is restored,
instead of 100Mbps or faster. The system will continue to link at 10Mbps
until the operating system is loaded. This setting will be restored when
the OS loads.

System Wakes Unexpectedly
-------------------------
On a driver only install, if you uncheck the "Allow this device to bring
the computer out of standby" option on the Power Management tab, the
adapter will still wake the system from Standby or Hibernate. The "Wake
on Settings" option on the Advanced tab must also be set to Disabled.

Auto Connect Battery Saver (ACBS) enabled NICs do not power up when
connected back to back
-------------------------------------------------------------------
If you have two systems, both running on batteries and both with
ACBS-enabled NICs that are in an ACBS state, and you connect them back
to back, the NICs will not power up. Since both NICs are powered down,
neither one can generate a link signal to wake the other. Either connect
AC power to one system or disable ACBS to resolve this issue.

Auto Connect Battery Saver (ACBS) does not function
---------------------------------------------------
ACBS will not function on an adapter if the adapter has forced speed
or duplex settings. ACBS will only function if the adapter is set to
auto-detect or auto-negotiate.

Wake on LAN is unavailable
--------------------------
Wake on LAN is supported on port A only on the following devices:
- Intel(R) PRO/1000 GT Quad Port Server Adapter
- Intel(R) PRO/1000 PT Quad Port Server Adapter
- Intel(R) PRO/1000 PT Dual Port Network Connection
- Intel(R) PRO/1000 PT Dual Port Server Connection
- Intel(R) PRO/1000 PT Dual Port Server Adapter
- Intel(R) PRO/1000 PF Dual Port Server Adapter
- Intel(R) PRO/1000 PT Quad Port LP Server Adapter
- Intel(R) PRO/1000 PF Quad Port Server Adapter
- Intel(R) Gigabit ET2 Quad Port Server Adapter
- Intel(R) Ethernet Server Adapter I340-T4
- Intel(R) Ethernet Server Adapter I340-T2
- Intel(R) Gigabit ET Quad Port Server Adapter
- Intel(R) Gigabit EF Dual Port Server Adapter
- Intel(R) Gigabit ET Dual Port Server Adapters
- Intel(R) Gigabit VT Quad Port Server Adapter
- Intel(R) Ethernet Server Adapter I340-F4
Wake on LAN is not supported on any port of the following devices:
- Intel(R) Ethernet Converged Network Adapter X710
- Intel(R) Ethernet Converged Network Adapter X710-2
- Intel(R) Ethernet Converged Network Adapter X710-4
- Intel(R) Ethernet Converged Network Adapter X710-T
- Intel(R) Ethernet Converged Network Adapter X710-T4
- Intel(R) Ethernet Converged Network Adapter XL710-Q1
- Intel(R) Ethernet Converged Network Adapter XL710-Q2

Most Intel 10GbE Network Adapters do not support Wake on LAN on any port.
The Intel(R) Ethernet Converged Network Adapter X550-T1 and Intel(R) Ethernet
Converged Network Adapter X550-T2 have a manageability/AUX power connector.
These devices only support WoL if AUX power is supplied via this connector.
Note that this is system and adapter specific. Some with this connector do not
support WoL. Some systems do not provide the correct power connection. See your
system documentation for details.

System Wakes-Up from a Removed VLAN
-----------------------------------
If a system goes into standby mode, and a directed packet is sent to the
IP address of the removed VLAN, the system will wake-up. This occurs
because a directed packet bypasses VLAN filtering.

Intel Network Adapters ignore consecutive Wake Up signals while
transitioning into standby mode
-----------------------------------------------------------
While sending a system into standby, occasionally a wake up packet
arrives before the system completes the transition into standby mode.
When this happens, the system ignores consecutive wake up signals
and remains in standby mode until manually powered up using the
mouse, keyboard, or power button.

Link flap when Energy Efficient Ethernet is enabled
---------------------------------------------------
Some switches do not support Energy Efficient Ethernet (EEE) correctly. Make
sure your switch is loaded with the latest firmware. Disabling EEE on your
adapter may resolve this issue.


Microsoft Windows* 8.1 and Windows Server* 2012 R2 Notes
========================================================

Some older Intel(R) Ethernet Adapters do not have full software support for
the most recent versions of Microsoft Windows*. Many older Intel Ethernet
Adapters have base drivers supplied by Microsoft Windows. Lists of supported
devices per OS are available at:
http://www.intel.com/support/go/network/adapter/nicoscomp.htm

Encapsulated traffic may fail when traffic is tagged and 'Packet
Priority & VLAN' option is disabled
----------------------------------------------------------------
If the 'Packet Priority & VLAN' advanced parameter is set to "Disabled,"
VLAN tagged packets will have incomplete destination information and may be
dropped by the physical switch. To ensure encapsulated traffic is not dropped,
verify that the 'Packet Priority & VLAN' advanced parameter is set to
"Enabled."

Virtual Machine Queues are not allocated until reboot
-----------------------------------------------------
On a Microsoft Windows Server 2012 R2 system with Intel(R) Ethernet Gigabit
Server adapters installed, if you install Hyper-V and create a VM switch,
Virtual Machine Queues (VMQ) are not allocated until you reboot the system.
Virtual machines can send and receive traffic on the default queue, but no
VMQs will be used until after a system reboot.

Link loss after changing the Jumbo Frames setting
-------------------------------------------------
Inside a guest partition on a Microsoft Windows Server 2012 R2 Hyper-V
virtual machine, if you change the jumbo frame Advanced setting on an
Intel(R) X540 based Ethernet Device or associated Hyper-V NetAdapter, you may
lose link. Changing any other Advanced Setting will resolve the issue.

DCB QoS and Priority Flow Control do not act as expected
--------------------------------------------------------
If you use Microsoft's Datacenter Bridging (DCB) implementation configure
Quality of Service (QoS) and Priority Flow Control (PFC), the actual traffic
flow segregation per traffic class may not match your configuration and PFC
may not pause traffic as expected. If you mapped more than one priority to a
Traffic Class, enabling only one of the priorities and disabling the others
will work around the issue. Installing Intel's DCB implementation will also
resolve this issue.
This issue affects Microsoft Windows Server 2012 and Server 2012 R2.


Microsoft Windows* 8 and Windows Server* 2012 Notes
===================================================

Some older Intel(R) Ethernet Adapters do not have full software support for
the most recent versions of Microsoft Windows*. Many older Intel Ethernet
Adapters have base drivers supplied by Microsoft Windows. Lists of supported
devices per OS are available at:
http://www.intel.com/support/go/network/adapter/nicoscomp.htm

Hot plug operations do not work as expected in the following reference designs:
Foxcove - Hot plug operations do not work.
Emerald Ridge - Hot plug operations work only if you have the latest BIOS.

In Intel(R) PROSet for Windows Device Manager, the help text may not initially
be displayed. The text should appear after switching between tabs a few times in
Intel(R) PROSet.

DCB QoS and Priority Flow Control do not act as expected
--------------------------------------------------------
If you use Microsoft's Datacenter Bridging (DCB) implementation configure
Quality of Service (QoS) and Priority Flow Control (PFC), the actual traffic
flow segregation per traffic class may not match your configuration and PFC
may not pause traffic as expected. If you mapped more than one priority to a
Traffic Class, enabling only one of the priorities and disabling the others
will work around the issue. Installing Intel's DCB implementation will also
resolve this issue.
This issue affects Microsoft Windows Server 2012 and Server 2012 R2.


Microsoft Windows* 7 and Windows Server* 2008 R2 Notes
======================================================

Microsoft Windows 7 and Windows Server 2008 R2 do not support Wake on
directed packet. Systems with these operating systems will not wake on a
ping or other directed packet.

Some older Intel(R) Ethernet Adapters do not have full software support for
the most recent versions of Microsoft Windows*. Many older Intel Ethernet
Adapters have base drivers supplied by Microsoft Windows. Lists of supported
devices per OS are available at:
http://www.intel.com/support/go/network/adapter/nicoscomp.htm

Flow Control is off by default
------------------------------
The inbox drivers for Intel network devices in Windows 7 and Windows
Server 2008 R2 have flow control turned off by default.


Intel(R) X710 and XL710 Network Adapter Notes
=============================================

In order for an Intel(R) 40GbE Network Adapter to reach its full potential,
you must install it in a PCIe Gen3 x8 slot. Installing it in a shorter slot,
or a Gen2 or Gen1 slot, will impact the throughput the adapter can attain.

Some Intel(R) X710 and XL710 based devices report a subvendor ID of 0x0000 and
may display a generic branding string. Port 0 reports the correct subvendor ID
and displays the correct branding string.

Intel X710/XL710 based devices may maintain link on any and all ports as long
as power is provided to the device, regardless of the device's or system's power
state.

Intel X710/XL710 based devices do not support Microsoft Windows Server 2008R2 or
Windows Server 2012 as SR-IOV Guest operating systems. These devices do not
support Windows Server 2012 as the SR-IOV Host operating system.

Supported SFP+ pluggable optical modules:
NOTES:
* If your Intel(R) Network Adapter came with Intel SFP+ optics, or
  is an Intel(R) Ethernet Converged Network Adapter X710 type of adapter,
  then it only supports Intel optics and/or the direct attach cables listed
  below, as well as the 3rd party modules listed in the table immediately
  following.
* Intel branded network adapters based on the X710/XL710 controller 
  (for example, Intel(R) Ethernet Converged Network Adapter XL710-Q1) support
  the E40GQSFPLR module. For other connections based on the X710/XL710
  controller, support is dependent on your system board. Please see your vendor
  for details.

X710/XL710 Based SFP+ adapters support all passive and active limiting direct attach
cables that comply with SFF-8431 v4.1 and SFF-8472 v10.4 specifications.

Intel ANS VLANs adversely affect performance
--------------------------------------------
Intel ANS VLANs adversely affect the performance of X710/XL710 based devices. Use
the networking features built into Microsoft Windows Server 2012, or other server
management software, to assign VLANs.

Diagnostic button disabled
--------------------------
When part of an Intel(R) ANS team, devices based on the Intel X710/XL710 controller
do not support diagnostics. Support will be added in a future release.

Traffic is not passed between Virtual NICs
------------------------------------------
SR-IOV Virtual Functions are unable to send or receive traffic between Virtual
NICs on the same physical port or between emulated connections on a Linux
Software bridge and connections that use SR-IOV VFs. Use an external switch
that is 802.1Qbg (VEPA) capable to workaround this issue.


Intel 10GbE Network Adapter Notes
=================================

Release 18.7 is the last release in which Intel 10GbE Network Adapters support
32-bit Microsoft Windows. Starting with Release 18.8, Intel 10GbE Network
Adapters only support 64-bit operating systems

Devices based on the Intel(R) Ethernet Connection X552 
do not support the following features:

Attaching the cable to the Intel(R) 10 Gigabit AF DA Dual Port Server Adapter
may require significant force. The cable must be latched in for proper
operation.

When 82599-based SFP+ devices are connected back to back, they should be set to
the same Speed/Duplex setting. Results may vary if you mix speed settings.

Some Intel(R) 10 Gigabit Network Adapters and Connections support SFP+
pluggable optical modules.

Intel 10GbE Network Adapter Known Issues
-----------------------------------------

Supported SFP, SFP+, or QSFP+ module not recognized by the system
-----------------------------------------------------------------
If you try to install an unsupported module, the port may no longer install
any subsequent modules, regardless of whether the module is supported or not.
The port will show a yellow bang under Windows Device manager and an event
id 49 (unsupported module) will be added to the system log when this issue
occurs. To resolve this issue, the system must be completely powered off.

Lower than expected performance on quad port 10GbE devices
----------------------------------------------------------
All SFP and QSFP quad port NICs based on the 82599 controller will link at
5 GT/s (PCIe gen2) when used in a system from Intel's Enterprise Platforms and
Services Division (EPSD). The PLX PCIe switch used on these NICs is not on
the EPSD white list of supported PCIe gen3 devices.
Devices not on the white list are blocked from linking at PCIe gen3 by the
production BIOS.

Lower than expected performance on dual port 10GbE devices
----------------------------------------------------------
Some PCIe x8 slots are actually configured as x4 slots. These slots have
insufficient bandwidth for full 10Gbe line rate with dual port 10GbE devices.
The driver can detect this situation and will write the following message in
the system log: "PCI-Express bandwidth available for this card is not
sufficient for optimal performance. For optimal performance a x8 PCI-Express
slot is required." If this error occurs, moving your adapter to a true x8
slot will resolve the issue.

Lower than expected performance on quad port 10GbE devices
----------------------------------------------------------
Quad port 10Gbe devices require x8 PCIe gen 3 slots. Full throughput is
not possible in a PCIe gen 2 slot.

Link Loss on 10GbE Devices with Jumbo Frames enabled
----------------------------------------------------
You must not lower Receive_Buffers or Transmit_Buffers below 256 if jumbo
frames are enabled on an Intel(R) 10GbE Device. Doing so will cause loss
of link.

Failed connection and possible system instability
-------------------------------------------------
If you have non-Intel networking devices capable of Receive-Side Scaling
installed in your system, the Microsoft Windows registry keyword "RSSBaseCPU"
may have been changed from the default value of 0x0 to point to a logical
processor. If this keyword has been changed then devices based on Intel(R)
82598 or 82599 10 Gigabit Ethernet Controllers might not pass traffic.
Attempting to make driver changes in this state may cause system instability.
Set the value of RSSBaseCpu to 0x0, or to a value corresponding to a physical
processor, and reboot the system to resolve the issue.


1GbE Quad Port Server Adapter Notes
===================================

Hot Plug operations are not supported by the following Intel Quad Port
Server Adapters:
Intel(R) Gigabit ET2 Quad Port Server Adapter

Intel(R) PRO/1000 PT Quad Port Server Adapter
Intel(R) PRO/1000 GT Quad Port Server Adapter
Intel(R) PRO/1000 MT Quad Port Server Adapter

System does not boot
--------------------
Your system may run out of I/O resources and fail to boot if you install
more than four quad port server adapters. Moving the adapters to different
slots or rebalancing resources in the system BIOS may resolve the issue.
This issue affects the following Adapters:
* Intel(R) Ethernet Server Adapter I350-T4
* Intel(R) Gigabit ET2 Quad Port Server Adapter
* Intel(R) Gigabit ET Quad Port Server Adapter
* Intel(R) Gigabit VT Quad Port Server Adapter
* Intel(R) PRO/1000 PF Quad Port Server Adapter
* Intel(R) PRO/1000 PT Quad Port LP server Adapter

Intel PRO/1000 GT Quad Port Server Adapter Not recommended
for use on some systems
----------------------------------------------------------
The Intel PRO/1000 GT Quad Port Server Adapter does not function
correctly in the following systems:

* SuperMicro* P4DP6 running SCO Unixware or OpenServer 6
* Intel(R) Server Board SE7505VB2 based systems (PCI slot 5 only. Other
slots work as designed)

Code 10 on Intel(R) PRO/1000 PT Quad Port LP Server Adapter
-----------------------------------------------------------
You may encounter a Windows Code 10 error with an Intel(R) PRO/1000 PT Quad
Port LP Server Adapter installed in slot #4 of a SuperMicro 7046T-H6R system.
Moving the adapter to another slot will resolve the issue.

Intel PRO/1000 MT Quad Port Server Adapter Known Issues
-------------------------------------------------------
The Intel PRO/1000 MT Quad Port Server Adapter operates in 3.3 volt
PCI-X slots only. For best performance, this adapter should be installed
in a 64-bit PCI-X slot. Refer to the detailed installation instructions
in the User's Guide for additional requirements.

Wake on LAN is not supported on the Intel PRO/1000 MT Quad Port Server
Adapter. Trying to enable this feature with IBAUTIL.EXE will not have any
effect.

The Intel PRO/1000 MT Quad Port Server Adapter supports Intel(R) Boot Agent
functionality on ports A and B, however it is disabled by default. To
enable and use the Intel Boot Agent, refer to the User's Guide and
other information in the \APPS\BOOTAGNT\ directory.

Multiple Intel PRO/1000 MT Quad Port Server Adapters in one system
------------------------------------------------------------------
Installing more than two Intel PRO/1000 MT Quad Port Server Adapters in
the same system is not recommended. Many systems are unable to support
the power requirements for more than two of these adapters.

Use only in a PCI-X Slot
------------------------
Reduced performance has been observed when the Intel PRO/1000 MT Quad
Port Server Adapter is installed in a slot other than a PCI-X slot.

Shared Interrupt Limitation
---------------------------
In some systems, the BIOS and OS assign the same interrupt number to
two or more different ports on the Intel PRO/1000 MT Quad Port Server
Adapter. If this occurs, these ports do not function properly. To
address this issue, reassign the system resources so that each port
of the adapter has its own unique interrupt number or disable one of
the ports sharing the same interrupt number.

Downshifting
------------
When connecting to any Gigabit switch via a faulty CAT 5 cable where
one pair is broken, the adapter does not downshift from 1 Gig to
100Mbps. For the adapter to downshift, it must identify two broken
pairs in the cable.

Intel PRO/1000 MT Quad Port Server Adapter Not recommended
for use on some systems
----------------------------------------------------------
The Intel PRO/1000 MT Quad Port Server Adapter does not function
correctly in the following systems:

Dell* PowerEdge* 2500
Dell PowerEdge 6400
Dell PowerEdge 6450
Dell PowerEdge 6650SC
Intel Saber, Saber-R, and Saber-Rx Systems
SuperMicro 370DE6
SuperMicro P4DP6
IBM* eServer* xSeries* 365

Using the Intel PRO/1000 MT Quad Port Server Adapter in these
configurations is not recommended.

Heavy traffic may cause system reboot in some systems
-----------------------------------------------------
Using an Intel PRO/1000 MT Quad Port Server Adapter may cause a reboot
in systems with the Intel Profusion chipset including: Intel OCPRF100
and SRPM8 server systems; Compaq* ProLiant* 8000, 8500, ML750, DL760;
Dell PowerEdge 8450, 6300, 6350; IBM* x370. Using the Intel PRO/1000
MT Quad Port Server Adapter in these configurations is not recommended.


Intel(R) Ethernet Desktop Adapter and Network Connection Notes
==============================================================

The Intel(R) 82562V 10/100 Network Connection and Intel(R) 82562V 10/100
Network Connection are supported by the gigabit drivers.

Release 20.6 is the last release in which Intel(R) Ethernet iSCSI Boot supports
Intel(R) Ethernet Desktop Adapters and Network Connections. Starting with Release
20.7, Intel Ethernet iSCSI Boot no longer supports Intel Ethernet Desktop
Adapters and Network Connections.


Known Issues
============

Driver Installation Issues on Microsoft* Windows* 10
----------------------------------------------------
Release 20.7 (or later) driver installs on Microsoft Windows 10 may time out
or fail due to extended wait time (up to 4 minutes per Ethernet port). In
most cases, despite the timeout, the driver installs correctly and is usable.
If the driver does not install correctly, retry the installation process.
Note that Intel(R) PROSet for Windows Device Manager relies on correctly
installed drivers.

Lower than expected throughput on X710/XL710 based devices
----------------------------------------------------------
If you have an X710 or XL710 based device installed in a four CPU socket
system. Receive and transmit traffic may be significantly lower than
expected. Setting your interrupt rate to High may mitigate the issue.

Link loss after identifying the adapter
---------------------------------------
All ports on the device may lose link when you run the diagnostic tests to
identify the adapter on a single port. Link will return to normal after several
seconds. This only affects 10G-BaseT devices based on the Intel(R) Ethernet
Controller X710.

System does not get link when connected to a 10GbE switch
---------------------------------------------------------
Systems that contain an Intel(R) i210 or i211 device may not link to a
10GbE switch. This may happen when the system's Ethernet cable is not
connected to the switch during power up or if the cable is disconnected
for more than a couple of minutes. Disabling and enabling the device in
the operating system will restore link.

iSCSI traffic stops after disabling RSC
---------------------------------------
To prevent a lost connection, Receive Segment Coalescing (RSC) must
be disabled prior to configuring a VLAN bound to a port that will
be used for connecting to an iSCSI target. Workaround this issue
by disabling Receive Segment Coalescing before setting up the VLAN.
This will avoid this traffic stop.

Multicast routing table is not automatically set up
---------------------------------------------------
The multicast routing table for the Intel(R) XL710/X710 Virtual Function
driver is not automatically set up and the virtual machine will not receive
multicast traffic. Manually adding the multicast routing will resolve the
issue.

Enable PME setting not set to expected value
--------------------------------------------
After running Sysprep, the Enable PME setting may not be set to the
expected value. You should manually verify and configure the setting.

Receive Side Scaling value is blank
-----------------------------------
Changing the Receive Side Scaling setting of an adapter in a team may
cause the value for that setting to appear blank when you next check it.
It may also appear blank for the other adapters in the team. The adapter
may be unbound from the team in this situation. Disabling and enabling the
team will resolve the issue.

CPU utilization higher than expected
------------------------------------
Setting RSS Queues to a value greater than 4 is only advisable for large
web servers with several processors. Values greater than 4 may increase
CPU utilization to unacceptable levels and have other negative impacts
on system performance.

RSS Load Balancing Profile Advanced Setting
-------------------------------------------
Setting the "RSS load balancing profile" Advanced Setting to
"ClosestProcessor" may significantly reduce CPU utilization. However, in
some system configurations (such as a system with more Ethernet ports than
processor cores), the "ClosestProcessor" setting may cause transmit and receive
failures. Changing the setting to "NUMAScalingStatic" will resolve the issue.

Unexpected link loss when connected to Netgear XSM7224S switch
--------------------------------------------------------------
The Netgear XSM7224s switch is sensitive to Energy Efficient Ethernet (EEE)
mode. Link flap errors will occur with several Intel devices when EEE mode
is enabled. Disable EEE mode to resolve the issue. This issue affects
devices based on the following:
* Intel(R) I350 controller
* Intel(R) 82579 series of controllers
* Intel(R) I217 series of controllers
* Intel(R) I218 series of controllers

Reboot Prompt Appears when modifying the Performance Profile
---------------------------------------------------------------------
In Microsoft* Windows Server*, after modifying the performance profile,
a reboot prompt may appear. The Intel(R) Ethernet FCoE boot was configured
and there is no need to reboot. The base driver reloads are blocked
if FCoE boot is configured and the system is connected to an FCoE target,
even if the system was booted locally.

Opening Windows Device Manager property sheet takes longer than expected
------------------------------------------------------------------------
The Windows Device Manager property sheet may take 60 seconds or longer to open.
The driver must discover all Intel Ethernet devices and initialize them before
it can open the property sheet. This data is cached, so subsequent openings of
the property sheet are generally quicker.

Audio or video distortion when LAN cable is connected or disconnected
---------------------------------------------------------------------
Momentary audio distortion or video playback issues may occur when you
connect or disconnect a LAN cable to the onboard Ethernet port.
Intel(R) 82577 and 82578 based network connections are affected by this
issue.

Reduced or erratic receive performance
--------------------------------------
Intel(R) 7500 chipset-based systems may experience degraded receive
performance. Increasing receive descriptors to 1024 will resolve the
issue. Disabling C-states in the system BIOS will also resolve the issue.

Activity LED blinks unexpectedly
--------------------------------
If a system based on the 82577, 82578, or 82579 controller is connected
to a hub, the Activity LED will blink for all network traffic present on
the hub. Connecting the system to a switch or router will filter out most
traffic not addressed to the local port.

Unexpected NMI with 82599-based NICs
------------------------------------
If you set the PCIe Maximum Payload Size to 256 bytes in your system BIOS
and install an 82599-based NIC, you may receive an NMI when the NIC attains
link. This happens when the physical slot does not support a payload size
of 256 Bytes even if the BIOS does. Moving the adapter to a slot that
supports 256 bytes will resolve the issue. Consult your system documentation
for information on supported payload values.

VLANs are not supported on VMQ enabled adapters and teams
---------------------------------------------------------
If you create a VLAN on a VMQ enabled adapter, the VMQ setting will
automatically be set to disabled. The same will happen if you create a
VLAN on a team whose member adapters have VMQ enabled.

Unexpected Connectivity Loss
----------------------------
If you uncheck the "Allow the computer to turn off this device to save
power" box on the Power Management tab and then put you system to sleep,
you may lose connectivity when you exit sleep. You must disable and enable
the NIC to resolve the issue. Installing Intel(R)PROSet for Windows Device
Manager will also resolve the issue.

Device Manager freezes on VLAN removal
--------------------------------------
Removing multiple VLANs from the Intel(R) 82576 Virtual Function device may
cause Device Manager to freeze. You must reboot the virtual partition to
resolve the issue.

SNMP errors in the System Event Log
-----------------------------------
Under Microsoft Windows 7 or Windows Server 2008 R2, you may see the
following error in the System Event Log: "The SNMP Service encountered
an error while accessing the registry key
"SYSTEM\CurrentControlSet\Servcies\SNMP\Parameters\TrapConfiguration"
The Windows 7 SNMP service start up isn't properly configuring the service
with a TrapConfiguration key. Perform the following to correct the issue:
1. Open Services applet (run services.msc).
2. Right click on SNMP Service, then select Properties.
3. Click on the Traps tab. Enter "public" for the Community name and
click Add to list.
4. Click on the Security tab. Click the Add button. Enter "public" and
click on the Add button.

System hang at login or shut down
---------------------------------
On the systems listed below, installing Intel(R) Gigabit Quad Port Server
Adapters may hang the system at the login screen or when shutting down.
This has been reported on:
* Intel(R) PRO/1000 PT Quad Port LP Server Adapter
* Intel(R) Gigabit ET Quad Port Server Adapter
And systems with the following motherboards:
* Intel(R) Server Board S5400SF
* Intel(R) Server Board S5000VSA
* Intel(R) Server Board S5000PAL
* Intel(R) Server Board S5000XAL
* Intel(R) Workstation Board S5000XVN
Installing system BIOS 97 or later will resolve this issue.

VLANs unsupported on some Intel devices
---------------------------------------
The following devices do not support VLANs:
- Intel(R) 82567V-2 Gigabit Network Connection
- Intel(R) 82567V Gigabit Network Connection

Direct Assignment in a Virtual Environment
------------------------------------------
The following Intel devices do not support Direct Assignment:
- All PCI devices
- All PCI-X devices
- Older PCIe devices

Reduced Large Send Offload performance
--------------------------------------
Large Send Offload (LSO) and IPSec Offload are not compatible. LSO is
automatically disabled when IPSec Offload is enabled. This may reduce
the performance of non-IPSec traffic. Confining all of your IPSec
traffic to one port and enabling IPSec Offload only on that port
may mitigate this issue.
On Microsoft Windows 8/Server 2012 and later, devices based on the
82576, 82599, and X540 controllers are not affected by this issue.

Hot Plug does not function in Microsoft Windows
-----------------------------------------------
On an Intel(R) Server System SR9000MK4U, the following dual port server
adapters cannot be removed using the system's Hot Plug functionality.
Use the Windows Safely Remove Hardware utility to remove the adapters.
Intel(R) PRO/1000 PT Dual Port Server Adapter
Intel(R) 10 Gigabit XF SR Dual Port Server Adapter
Hot Add operations may fail on Intel(R) Gigabit ET Dual Port Server
Adapters. Doing so may cause a code 12 error. Hot Replace operations
function normally.

Dropped Receive Packets on Half-duplex 10/100 Networks
------------------------------------------------------
If you have an Intel PCI Express adapter installed, running at 10 or
100 Mbps, half-duplex, with TCP Segment Offload (TSO) enabled, you may
observe occasional dropped receive packets. To work around this
problem, disable TSO, or update the network to operate in full-duplex
and/or 1 Gbps.

Lost SOL and IDER sessions
--------------------------
SOL and IDER sessions may be lost if spanning tree is enabled. Turn off
spanning tree protocol on switch ports connected to devices configured
for SOL and IDER access.

Procedure for installing and upgrading drivers and utilities
------------------------------------------------------------
Intel does not recommend installing or upgrading drivers and Intel(R)
PROSet software over a network connection. Instead, install or upgrade
drivers and utilities from each system. To install or upgrade drivers
and utilities, follow the instructions in the User Guide.

Installing Intel PROSet and Intel PROSet for Windows Device Manager on
the same system
----------------------------------------------------------------------
The Intel PROSet install process prevents installing both Intel PROSet
and Intel PROSet for Windows Device Manager on the same system. When you
install Intel PROSet for Windows Device Manager, prior versions of PROSet
are uninstalled automatically.

"Malicious script detected" warning from Norton AntiVirus* during
PROSet Uninstall
-----------------------------------------------------------------
The Intel PROSet uninstall process uses a Visual Basic script as part of
the process. Norton AntiVirus and other virus scanning software may
mistakenly flag this as a malicious or dangerous script. Letting the script
run allows the uninstall process to complete normally.

"Out Of Disk Space" Message during Installation
-----------------------------------------------
The boot partition requires a minimum of 15 MB free space in order to install
Intel PROSet, regardless of which drive you specify for installation. If
there is insufficient space on the partition you will see this error
message, and the product will not install.

Windows Code 10 Error Message on Driver Install or Upgrade
----------------------------------------------------------
If you encounter a Windows Code 10 error message when installing or
upgrading drivers, reboot to resolve the issue.

Throughput reduction after Hot-Replace
--------------------------------------
If an Intel gigabit adapter is under extreme stress and is hot-swapped,
throughput may significantly drop. This may be due to the PCI property
configuration by the Hot-Plug software. If this occurs, throughput can
be restored by restarting the system.

No settings available on the Intel(R) Boot Options tab in Windows Device
Manager after flashing an EFI image
----------------------------------------------------------------------
The settings have been hidden because the EFI environment does not make
use of them.

Red Screen with 5400 general exception error after
lanutil64 -blink -all command
--------------------------------------------------
Using the EFI lanutil64 utility to blink the identification LEDs on all
network connections on systems that contain Intel PRO/100 devices may
cause the system to crash with a 5400 general exception error. Using the
utility to blink the identification LED on an individual network connection
will not cause the system to crash.

Link Difficulties With 82541 or 82547 Based Connections
-------------------------------------------------------
The PROSet Advanced tab now contains a setting allowing the
master/slave mode to be forced. This improves time-to-link with
some unmanaged switches. For older adapters and controllers, you
may encounter difficulty with 82541 or 82547 based connections.

Using Intel PRO/1000 XT or T Adapters and e1000ODI.COM Driver
-------------------------------------------------------------
In some cases, an Intel PRO/1000 T or PRO/1000 XT adapter or network
connection using the e1000ODI.COM driver will not receive traffic.
You can fix this problem by disabling Wake On LAN (WOL) in the
adapter hardware before connecting to the network.
Use IBAUtil to disable WOL. For more information, see the IBAUTIL.TXT
file for more information (\APPS\BOOTAGNT directory).

Intel Gigabit Network Adapters (copper only) do not detect active
link during load time
-----------------------------------------------------------------
Some Intel Gigabit Network adapters, especially copper adapters, cannot
detect an active link during load time. To resolve this issue, try
the following workarounds.
- Re-attach to the server without reloading the driver.
- For DOS-based installations, add a delay of 4 to 5 seconds in the
batch file after the load driver command.
- Load the configuration by manually entering commands.
- Set adapter to link at 1000 Mbps only.

Network stack will not enable RSC
-------------------------------------------------------
If Intel Data Center Bridging (DCB) is installed (FCoE, iSCSi, or both),
the network stack will not enable Receive Segment Coalescing (RSC).

PXE option ROM does not follow the PXE specification with respect to the
final "discover" cycle
------------------------------------------------------------------------
In order to avoid long wait periods, the option ROM no longer includes
the final 32-second discover cycle. (If there was no response in the prior
16-second cycle, it is almost certain that there will be none in the final,
32-second cycle.

  • Find the device and model you want to update in the device list.

  • Double-click on it to open the Properties dialog box.
