Hi,

I use Windows 8 PRO 64bit and installed the HYPER-V and created an external LAN allowing the host to share NIC . As soon as created the external LAN, i lost the internet connection on HOST, but the virtual Machine is able to connect to internet. If i disable he virtual network and then re-enable it, from network properties, the connection works both on host and on virtual.
But if i reboot the host, i'm in the same situation as before, and have to disable and then enable again the virtual network.

Any clue ? It seems i'm not the only one having the issue, but can't find a permanent solution.

Many thanks in advance

Hello,

Short story - cannot receive ipv6 packets in a KVM guest using SR-IOV interfaces (VF), but, ipv4 works fine.

Long Story:

Have 2 KVM VMs set up on 2 separate hosts. OS in the host and the guest is RHEL6.4. The hosts use the 82599 NICs.  Have assigned a VFs to each guest (eh4/eth5) using unique mac addresses in the XML guest definition (the other interfaces in the VM are bridged interfaces).  Assigned a unique VLAN to each VF per VM (eth4 is 610, eth5 is 611) using 'ip link set' commands.  Using Intel provided driver ixgbe (3.15.1) on the host and ixgbevf (2.8.7) in the guest. Plumbed ipv4 and ipv6 IP in the guests for eth4 on each VM.  Ping (ipv4) works fine.  We can see the packet enter the NIC  on the receive side host (tcpdump) and can see it in the guest too.  When we repeat the process for ipv6, it fails.  It leaves the guest fine, we see it hit the NIC on the received host), but it is NOT received by the guest across the VF.  If we pull out the VFs and replace with bridges, ipvv6 works fine so it's not a routing/network issue. 

Is there something we need to set up/configure to get ipv6 to show up in the guest??  Note we can also ping out successfully to the upstream L3 switch (subnet gateway), but not to the other VM.

Thanks,

Shawn

Hi! I would like to know what are the difference between

E10G42BTDA and E10G42BFSR

the first one has a cable type:

SFP+ direct attached

twin axial cabling up to 10 m

and the second one:

MMF 62.5/50 μm

up to 300 m

I need to use the E10GSFPSR. Wich one of the previously mentioned network adapter is compatible with this sfp+ module?

And what about your E10G41BFSR?

Thank you.

Kaiyu

I recently reloaded an older PC (Intel DQ965GFEKR - 82566DM), and decided to use the 16.5 package upon reinstall.  I noticed that network transfers to and from this PC were slower than usual, and I found that it was negotiating at 100Mb/Full Duplex.  I tested another PC (Intel DQ67SW - 82579LM) with the same cable/switch etc. and it auto-negotiates at 1Gb/Full-Duplex.

After trying a few things this is what I've found:

- LAN driver packages 16.4 and 16.5 both auto-negotiate at 100mb/Full Duplex since they both use the same driver (e1exxxx.sys 9.14.180.0)

- LAN driver package 16.3 auto-negotiates at 1Gb/Full Duplex (e1exxxx.sys 9.13.41.0)

- The results are the same whether I install the PROSet software or just bare drivers.

- If I force 1Gb / Full Duplex, the network connection disconnects.

- I've tried Windows XP x86 (SP3), Windows XP x64 (SP2),  Windows Vista Business x86 (SP1), and Windows 7 Pro x86/x64 (SP1), all with the same

result (16.3 - 1Gb, 16.4/16.5 - 100Mb)

- BIOS version on the DQ965GFEKR is 6100, and I also tried 6077.

- I've tried another PC with the same motherboard (DQ965GFEKR - 82566DM) and it produced the same result as well.

Here are a few screenshots of Win7 Pro x86 with 16.3 and 16.5:  http://imgur.com/a/8SzTV

I'm not sure whether other ethernet controllers that use this particular driver are affected.  In any case, I'm running with the 16.3  package right now and all is well

Has anybody else noticed this issue with either this or another supported ethernet component supported by this driver?

Just purchased an ASRock Z87 Extreme6 board which has dual Intel NICS (I211 & I217-V).  I'm running Win7 64-bit.  I installed the 18.3 driver package with the ProSet and ANS boxes checked.  Installation completes without any issues.  Both NICS work fine, but in the device manager, I have no extra ANS tabs (VLAN, Teaming, etc).  I've tried uninstalling and reinstalling the drivers several times along with trying the 18.2 package that's on the ASRock driver disc.  If I uninstall ProSet for device manager and ANS, I get the "Advanced" tab.  As soon as I reinstall both, the "Advanced" tab disappears and I get what you see below.  I've made sure the WMI service is running, and Windows Modules Installer is running during the driver install.  I'm not sure what else to try.

Below is what I see in the device manager for both NICS:

Any help is greatly appreciated!

Hello,

What is the most reliable way to identify that a given Virtual Function ( given a bus:address:function) belongs to a PF and to a particular por

I saw that vfs with even/odd numbered function belongs to the first/second port/pf respectively.  But I have not seen this convention officially stated in the 82599 datasheet.  Is there a more reasonable and reliable way?

Environment:

OS:  ubuntu 13.4

NIC:  82599 eb

tIn our network environment all workstations are equipped with onboard Intel NICs, e.g. 82567LM-3. All these workstations are configured to power on by Wake-on-LAN. I've noticed workstations that are powered off have a network link established with 10MBit, which should be enough to receive the magic packet.

Now to our problem, some of these workstations are connected by Fiber-to-Copper-Converters to the network core only supporting 1000Base-T, there is no way to establish a link with lower speed than 1GBit. As result the link is lost when the affected workstations are powered off with no more possibility to wake them by WoL.

Is there a way to configure the onboard NIC to stay with a link speed of 1GBit when the workstation is powered off?

Hello,

I'm using Windows 7 embeded and SFT teaming on 2 adapters.

On this teaming, 3 VLANs are created.

I want to garantie my path so I configure the connection monitoring to probe one of my network equipement.

I ran Wireshark to analyze this traffic and here are some interresting points I saw :

- If I enter the management IP of one of the Cisco switch, no answer.

- If I probe a Ubunter server, no answer

- If I probe a Windows server (or desktop) it's OK

Furthermore with Wireshark (1.8.4) the frames sent by the driver are seen as "Ethernet Frame check sequence incorrect" and look like that :

Sender MAC address: Bull_38:67:b0 (08:00:38:38:67:b0)

Sender IP address: 0.0.0.0 (0.0.0.0)

Target MAC address: 00:00:00_00:00:00 (00:00:00:00:00:00)

Target IP address: 10.24.5.254 (10.24.5.254)

I saw that some equipments doesn't answer because the frame has no IP source so I want to know if there is any trick to specify the IP source (regedit, config file etc.) ?

Thanks

The advanced network services virtual adapter is not working for windows 8.1. Worked great for Win 8....any help would be greatly appreciated!

Please Intel, new drivers...thanks!

Need some advice on selecting a network adapter for maximizing internet browsing performance with my Cox Communications cable internet service and ethernet connection.

The computer is a HP Z220 with i5-3470 cpu, Samsung 840 Pro SSD, and Windows 7 Pro 64 bit. The current controller is the standard embedded Intel 82579LM .

Would I get better internet performance such as faster page loads, less delays, faster downloads, if I installed a Intel EXPI9301CT or PWLA8391GT adapter? Or something else? My current performance is not slow but I am online quite a bit and would like to save any time that can be saved through better performance.

Suggestions appreciated!

Hi everyone,

We purchased a few DELL Optiplex 9020s that came with an Intel Ethernet Connection I217-LM ethernet controller, and I've been unable to find the correct WinPE x64 drivers for this adapter.

From the Download Center I found what I thought were the correct drivers. In the EXE, I found some WinPE drivers, but apparently these aren't it as I'm not able to connect to my network when I boot up using WinPE.

Can anyone point me in the right direction to get the correct drivers please?

Thanks!

Hello,

I ordered 15 X540-T2 cards from Dell only to find out that they don't include the full-height bracket:

2-port Intel Ethernet Converged Network Adapter X540-T2 - network adapter - 2 ports : Computer Components | Dell

The description says low profile, but I assumed that refers to the card itself. All other places where the card is sold state that it comes with both brackets, so I never imagined that Dell is selling something different. I've already contacted their support to see if we can get the brackets separately, but if not, is there another source from which we could get them? I couldn't find anything. I'd really like to avoid having to return these cards, but we can't install them in our servers as it stands.

Thanks!

First a bit about my environment:

• Dell PowerEdge 2970
• Intel Quad-port I340-T4 10/100/1000 Ethernet HBA
• Intel driver version: 12.7.28.0 (installed drivers and PROSet using PROWinx64.exe, v. 18.3)
• Microsoft Windows Server 2008 R2 Datacenter w/SP1 (Core, with Hyper-V role)
• Cisco (Linksys) SRW2016 16-port full GbE (10/100/1000) switch

I used PROSetCL.exe and the SRW2016 web management interface to configure a 3-port LAG (in LACP mode). The NIC team comes up fine and I'm able to use it for "normal" network stuff. The teamed interface is used by the virtual servers / guests for network connectivity. I'm not doing anything with VMDq yet, although I'm interested in exploring it after I get VLANs working with teaming. Here is the output for PROSetcl.exe Team_GetTeamInfo 1:

1) TEAM : VMNetwork

   Team Information:

       Team GUID       - '{305A7788-9AFC-4DD4-9B47-2CF0CF70412B}'

       Team MAC        - '001B21AEB9A5'

       Team Mode       - 'IEEE 802.3ad Dynamic Link Aggregation'

       Team Name       - 'VMNetwork'

And the output for PROSetcl.exe Team_EnumerateAdaptersInTeam 1:

1) TEAM : VMNetwork

   Number of adapters currently present: 3

       4) TEAM : VMNetwork - Intel(R) Ethernet Server Adapter I340-T4

       3) TEAM : VMNetwork - Intel(R) Ethernet Server Adapter I340-T4 #4

       2) TEAM : VMNetwork - Intel(R) Ethernet Server Adapter I340-T4 #3

On the SRW2016, the LAG corresponding to these 3 network interfaces is configured for VLAN trunking, untagged in VLAN 1 and tagged in all other VLANs. Somewhere in my explorations, I stumbled on a suggestion to also configure individual ports for VLANs, but when I tried this on the SRW2016, it wouldn't let me add the ports to a LAG. So, I can configure VLANs on a LAG, but the individual ports (apparently in trunk mode) are excluded from all VLANs.

I haven't set any VLAN configuration (using PROSetCL.exe) on the team (or individual NICs) in Hyper-V, and the related documentation I've read suggests that not only is it unnecessary, doing so is undesirable. My understanding is that if I set any VLAN configuration at the Hyper-V host level, then I must configure all VLANs I wish to be used by Hyper-V guests.

See:

http://www.intel.com/support/network/sb/cs-030993.htm

http://social.technet.microsoft.com/wiki/contents/articles/151.hyper-v-virtual-networking-survival-guide.aspx#Understanding_Hyper-V_VLANs

http://www.aidanfinn.com/?p=10164

For Hyper-V host management, I'm using a separate / dedicated NIC (not the teamed NIC interface) not involving VLANs. So, in Hyper-V's virtual switch connected to the teamed network interface, the option Allow management operating system to share this network adapter is unchecked, and there are no VLAN settings at that level.

One Hyper-V guest (running Windows Server 2008 R2 Standard) is multi-homed (two hybrid virtual network adapters). One of the adapters is configured for VLAN identification (in Hyper-V's settings, not inside the guest OS). Inside the guest OS, an appropriate IP address is assigned to the adapter, but the guest cannot communicate with other hosts on the VLAN it is configured for.

I'm just now beginning to think I should be using VMLB instead of LACP...? Am I correct in thinking that with VMLB, teaming is one-sided, meaning the physical switch knows nothing of the team configuration, and physical switch ports are configured individually? Or do I need a physical switch that understands / supports VMLB?

I would appreciate any suggestions on troubleshooting or getting this to work.

Thank you!

Hello,

When attempting to do remote boot with one port from an on-board (Dell PE720) i350-T4 as primary and one port on an add-on i350-T2 as secondary, I am unable to get Windows (2008 R2 w/SP1 & 2012) to recognize the "drive" during setup. I tried switching the primary/secondary roles of the T2 and T4 cards with the same behavior. The volume connects successfully to our iSCSI SAN and everything looks perfectly normal during POST as well.

We have 30 or so servers in our datacenter booting from our iSCSI SANs using similar configurations and I haven't run into any issues with those. All of the other servers are using older Intel or Broadcom adapters and work great booting from the SAN.

Is there something else I need to do to get this working? Is there a missing driver somewhere that needs to be loaded at OS installation time?

Thanks!

Hello everybody,

We are trying to set up FPP with SR-IOV using different amounts of virtual functions on 82599EB 10G-Cards.

Unfortunately we get extensive packet loss (50-99%) receiving at rates over 1.19Mpps.

This does not happen if no virtual functions are used at all (rates up to 14.4Mpps with negligible packet loss).

We are using the following drivers:

Does someone have further information about this issue and about how to reach higher receiving speeds without packet loss?

Thank you and best regards,

Ive got the Intel DQ67EP board with the Intel 82579LM onboard NIC.  Ive got the machine running Windows7 64bit.  Ive got this problem where randomly it drops from Gigabit to 10Mbps and will never negoiate back to gigabit.  I can disconnect the cable, reconnect it, dont work.  I can plug that same cable into another machine like my Lenovo T420 laptop, and it has no issues connecting gigabit, so I know its not the cable, or port, or Hub.  However still plugged into a different port of the hub, still dont work.  Plugged it into a different hub, still dont work, still keeps sitting at 10Mbps.

Ive rebooted it, still negoiates at 10Mbps.  Shut the PC down, wait 1min, turn it on, still sitting at 10Mbps.  So at this point dont believe its driver.  I have the latest 16.5 running on the Windows.

ONLY way I can get this working is one of two ways.  I have to unplug power, not just shut it down.  I need to kill power from the board entirely.  Wait 10secs, then plug it back in.  Then upon starting up, its set to gigabit with no issues.  Other way is to change a setting in Bios which when you exit/save it causes it to kill power to the board for a second.  So the fact that killing power to the board fixes it, tells me its some hardware or firmware level issue, clearly not the driver.

Now to explain when it happens, I do have the machine set to sleep and wake at certain times.  Most of the time it sleeps fine, wakes up fine and still sits at Gigabit.  Theres no explanation on how many times it takes before it decides to go into some stuck state of only negoiating at 10Mbps.  Even going into Device Manager and setting it to 100Mbps, or 1000Mbps, Half or Full duplex does nothing.  It disconnects the Link and Reconnects but only sits at 10Mbps.  Im normally connected via the IntelAMT via RealVNC.

Ive updated from the 0054 bios to 0055 last week so Im also on the latest Bios revision.

What causes this to get in such a stuck state that only killing power to the board fixes this?
