Can anyone help me with this question? Thank you!

My OS is win7 64bit. The computer is joined the company domain. The PC is HP Elitebook 820.

We have another PC HP 840 with same card can see these frames. It is win10 pro.  This computer is not joined any domain.

I have tried to add a "Monitor Mode“ key in the registry but seems not work. What settings should I change?

I am using the Wireshark 2.2.3 and P-cap 4.1.3

Win7 64 Enterprise

I want to change I350 PCIe  link speed to Gen1 from EEPROM but I don't know address, who can help~

Hello.

I started a new thread, because the old thread (SNMP issue with ANS ) don't have any answer from Intel's team since 2013 year.

I have installed the last version of PROWinx32.exe (21.1) with activation of the SNMP option on Windows 7 (32-bit).

I have configured an AFT teaming  from two network interfaces. By using PROSetCL.exe, I have checked that this teaming works correctly.

My problem is when I make a SNMP dump of the intel-Ian-adapters MIB, I have the following results:

• baseDriverLoadedAnsNotLoaded(1) for the status when I am expecting baseDriverLoadedAnsLoaded(3)
• standAlone(0) for the type of the adapters involved in the teaming when I am expecting teamMember(1)
• no data under ansAttrTables MIB subtree.

Previously, we used data from ansAttrTable MIB subtree on Windows XP with PROWin32.exe (v16.3) without any problems.

Under Windows 7 with the same (v16.3) driver and latest (v21.1) driver no data under ansAttrTable MIB subtree.

Is there something specific to do to have ANS loaded at SNMP level ?

Hi,

We are using 82576 Gigabit Ethernet Controller, as per the document (8.10.1 Receive Control Register - RCTL (0x00100; R/W)

, page No. 515) attached and also the ethtool output,

- Even if the UPE (Unicast Promiscuous Enable) bit is reset (disabled) we still seem to receive any Unknown Unicast Packets.

- If we disable the MPE (Multicast Promiscuous Enable) bit then we stop receiving any Unknown Unicast Packets.

While I do not see any reason why any one would disable UPE and enable MPE, just wanted to know if it is expected behavior.

Our assumption was that if the UPE bit is disabled then we should NOT receive any Unknown Unicast (assume we do not have any

RAL entries for MAC filtering)

Hi,

I have recently purchased X710-DA4 Network cards. My goal is to use the 10Gb link to receive data almost at full line rate.

The data is going to be received by the server which has the X710 installed. So the traffic is one way only.

I need to utilize the full line rate and store the data to SSD RAID.

The question is which operating system, libraries, would give the best performance?  I heard of the DPDK library but not sure whether it will be the best solution. Does Intel have its own libraries to achieve optimal performance?

Best Regards

Good day!

Our server configuration:

Microsoft Hyper-V Server 2012 R2 (core)

Supermicro X9SCM-F

- two Intel onboard network adapters: 82574. 82579 (do not work with WinSrv 2012)

I recently bought an I350-T2 dual port network adapter for this server and after driver installation I see "No active network adapters found" again

Drivers were downloaded from Intel web site (v.21.1)

msinfo32 says:

network adapters are present

driver: e1r64x64.sys

Please help me resolve this issue with drivers!

Is there any possibility to get an 540-T2 running on Windows 10 1607?

After Driverinstallation i got an Code 10, Driver could not be startet Error.

Thanks for any Help.

Hi,

Is there a document/brief that shows all the supported functions on the 8950 QAT plug in card?

Thanks,
Jackson

Are any of the pins on the I350T2V2BLK for an LED connection? I want to connect a LAN indicator LED on the front of the server case to this NIC.

Hi!

There is a dual E5-2690v3 box based on  Supermicro SYS-2028GR-TR/X10DRG-H, BIOS 1.0c, running Ubuntu 16.04.1, w. all current updates.

It has a XL710-QDA2 card, fw 5.0.40043 api 1.5 nvm 5.04 0x80002537, driver 1.5.25 (the stock Ubuntu i40e driver 1.4.25 resulted in a crash), that is planned to be used as an iSCSI initiator endpoint. But there seems to be a problem: the log file fills up with "RX driver issue detected" messages and occasionally the iSCSI link resets as ping times out. This is critical error, as the mounted device becomes unusable!

So, Question 1: Is there something that can be done to fix the iSCSI behaviour of the XL710 card? When testing the card with iperf (2 concurrent sessions, the other end had a 10G NIC), there were no problems. The problems started when the iSCSI connection was established.

Question 2: Is there a way to force the card to work in PCI Express 2.0 mode? The server downgraded the card once after several previous failures and then it became surprisingly stable. I cannot find a way to make it persist though.

Hello

I have 10 host Dell R730xd with Ethernet Converged Network Adapter X710-DA4 and we have installed VMware 6.0u2 hosts and vSAN. The cards at first seem to work well and preform well however we now have an issue where the links on all of our hots flap and performance is very poor.The logs show

TX driver issue detected, PF reset issued. and drop packages.

I search information and show issues with drivers Intel X710 and Vmware 6.0u2 and with Beta 1.6.6?

Thanks 

Setup:

• I have a Gigabyte GA-B150M-D3H motherboard with an Intel i5-6500 CPU and 8Gb DDR4 GSkill RAM.
• I have wired ethernet with a CAT5e cable plugged from the Ethernet port into a TP-Link Gigabit 5 port switch and then eventually onto a TP-Link ADSL2 Router.
• I am using a static IP setup (Static IP, Gateway, Subnet mask).
• I am running Windows 10 Home 64bit
• I am running Kaspersky 2017 Internet Security (I have uninstalled Kaspersky Secure Connection)
• I am running the supplied Gigabyte drivers for the Intel Ethernet Adapter on the board (Version 20.7 - listed as 12.15.22.3 in the driver properties)

Problem:

• Waking from S1 sleep causes the adapter to intialise at 10Mb/s and have no connectivity. The only solution is 1) reboot or 2) remove and re-insert the CAT5e cable. This cable has worked at Gigabit speeds for years on the previous Motherboard I had which had a Realtek based ethernet adapter on a GA-X38-DQ6.

Event Logs:

• When the problem occurs: "Intel(R) Ethernet Connection (2) I219-V Network link has been established at 10Mbps full duplex."
• When the system works fine: "Intel(R) Ethernet Connection (2) I219-V Network link has been established at 1Gbps full duplex."

Things I have tried:

I have tried the following Intel drivers:

• 20.4.1 (from the Intel site)
• 20.7 (from the Gigabyte site)
• 21.1 (from the Intel site)

I have tried disabling all of the power management properties in the Intel driver properties

Hi,

I have a NUC6i3SYK and want to enable WOL. I use a fritz Box to send the magic packet but the NUC doesnt power on.

In the Bios settings I have enabled Wake on Lan and also in Windows Device Manager. Bios is the latest version.

What could be wrong?

Cheers

Hello,

after the update to Windows 10 (x64, Build 10240) the creation of a teaming group (static or IEEE802.3ad) with a I211+I217-V NIC fails.

Drivers have been upgraded to the latest version available and multiple reinstallations with reboots din't help either. Whenever the group creation wizzard is used and a groupname (several tried), the adapters and LACP have been selected, a Windows pop-up appears to tell me group creation has failed.

However the Windows Device Manager shows a newly created "Intel Advanced Network Services Virtual Adapter", so some kind of configuration seems to get done.

Using Windows 7 SP1 x64 the exact same setup worked flawlessly for months, so Win10/the driver are the likely culprit.

Is anyone experiencing similar problems and/or is this a known bug? Feedback on this issue is greatly appreciated.

Thanks in advance!

Kind regards,

Famaku

Hi,
 
  we are experiencing packet reordering and thus bandwidth drops due to retransmissions on our servers. We are using RedHat 7.2 on HP Servers connected to a HP Aruba 1920 10GB switch. I can easily reproduce the issues by running iperf3 between the two servers. I have found a description of problems caused by Flow Director and migrating processes from Fermilab (https://arxiv.org/pdf/1106.0443.pdf) together with a support case at RedHat (https://access.redhat.com/solutions/2403071). What is offical position concerning this issue? Is it considered as bug?

An iperf test shows the retransmissions every couple of seconds:

  iperf3: interrupt - the client has terminated

In this test, I get some retransmissions every couple of seconds. We analyzed the retransmissions by capturing a sample with Wireshark and we can confirm that the retransmissions are fast retransmissions caused by reordering of the traffic at the receiving server only.
 
The RedHat case recommends to either switch to Perfect Filtering or fix CPU assignment of processes. I have tried both solutions, but the first one still produces retransmissions even when pinning both iperf processes to a fixed CPU:

taskset 0x1 iperf3 -s -p 12345

  iperf3: interrupt - the client has terminated

Switching to Perfect Forwarding mode fixed the problems and iperf runs without retransmissions. Are there other factors that can cause retransmissions, e.g. irq balancing at the receiver?

Got Supoermicro server from supplier  with X710-DA2 Card

I'm install FreeBSD 11, update to stable and have next messages:

ixl0: The driver for the device detected an older version of the NVM image than expected.

So I try update NVM under FreeBSD:

Hi

Using Intel PRO/1000 PT on Dell 3020 & Dell 390 connected to same device type one at the time. 

The device works fine for hours or days and suddenly the link start toggling
off and on every few seconds. 

The windows events log show ID 27 followed by the description:

The description for Event ID 27 from source e1express cannot be found. Either the component that
raises this event is not installed on your local computer or the installation is corrupted.

You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

    The following information was included with the event:
\Device\NDMP7  
Intel(R) PRO/1000 PT Dual Port Server Adapter #7

Any idea?

  Thanks.

- other party says link up no matter what - any clue ?

Thanks
