Does the I340-F4 support 100base-FX SFP modules

webadmin@intel.com — Tue, 21 May 2013 18:00:10 GMT

We am looking for a quad port PCI express card with 100base-FX interfaces, under Windows 7 32-bit. Does the I340-F4 support 100base-FX SFP modules?

I am not sure if SFP modules are plug-and-play for different speeds / wavelengths.

As background, we currently are using I340-T4 cards with external media convertors between copper and the external 100base-FX systems, and are looking for a replacement card with support for 100base-FX so can avoid the need to user media convertors. The required number of ports, and available motherboard slots, limit us to quad port PCI express cards.

NetEffect 10Gb Adapter Compatibility

webadmin@intel.com — Fri, 03 May 2013 19:41:08 GMT

etnerCan any of the following 3 NetEffect 10Gbe Ethernet Adapters that use PCIe v1.1 x8 lane be used on a Dell 2950 II that has PCIe v1.0 with an open x8 slot? I have not been able to find any other 10Gbe network adapter that supported anything less than PCIe 2.0+ so if this will work I can purchase my 10GbE iSCSI storage array.

NetEffect™ Ethernet Server Cluster Adapter CX4

NetEffect™ Ethernet Server Cluster Adapter DA

NetEffect™ Ethernet Server Cluster Adapter SFP+ SR

System Interface Type

PCIe v1.1 (2.5GT/s)

Speed & Slot Width

2.5 GT/s, x8 Lane

Thank you,

Disabling anti-spoofing protection on a VF (NIC 82576)

webadmin@intel.com — Thu, 02 May 2013 17:39:32 GMT

Hello,

I have a 82576 NIC for which I enabled SR-IOV support. All seems to work fine except I want to disable the anti-spoofing proctection (as described here [1]) and the command fails:

# ip link set dev eth0 vf 0 spoofchk off

RTNETLINK answers: Operation not supported

Anybody having a clue for this?

Distribution: Ubuntu 12.10

Kernel: 3.5.0-27-generic

igbvf driver: 2.0.1-k

Dell Optiplex 780 with 82567LM-3

webadmin@intel.com — Thu, 02 May 2013 16:55:25 GMT

I have a Dell Optiplex with an Intel 82567LM-3 Gigabit ethernet card and using unicast WOL. I have the most recent BIOS with deep sleep disabled and wake from off enabled. The problem is getting the computer to wake with unicast. The option for arp offloading and ns offloading does not appear to be supported by proset or the most recent intel driver with this chipset.

How can we get unicast to wake the computer up?

Edit:

If you recommend a new card, we want it to support Gigabit, AMT, WOL and ARP Offloading and it must be half height, PCI 2.3. Finding a card at the Intel site that matches these requirements has me totally lost. Can anyone recommend one?

82599 VF to Linux host bridge

webadmin@intel.com — Tue, 30 Apr 2013 22:34:21 GMT

We are configuring VFs for our high-volume network traffic, but want to continue to use Linux bridging for other VMs. Is there some configuration we need to do to enable packets from a VF to be switched to a bridge off the eth0 PF?

We create several VMs. One of them has a high volume of traffic, as it serves as a load balancer. It takes external traffic on one VLAN, and distributes it to other VMs on a different VM. If the different VM is on the same host, the packets are never switched in the 82599 back to the eth0 for feeding into the Linux bridge. We are using Red Hat EL 6.4. We have been able to get VM to VM traffic working on the same host, if both VMs use VFs, but are unable to get VM to VM traffic if one is using VF and the other is using bridges.

Suggestions?

Unable to PXE boot guest using SR-IOV VFs

webadmin@intel.com — Tue, 30 Apr 2013 21:34:51 GMT

Hello,

Config-centric info:

Using HP BL460C-G8 and 560FLB (82599 based) NIC. Host and guest OS is RHEL6.4 (latest - 2.6.32-358.2.1.el6.x86_64). Guest is defined SRIOV interfaces, but when booting, the bios doesn't appear to see any NICs and hence does not pxe boot (seen by examining the BIOS (seabios) output in the console). BTW, we are using libvirt and KVM.

I believe I need to create an optional ROM to load into libvirt, but when trying to build for ipxe, it fails. gpxe which ships with RH (latest - gpxe-roms-qemu-0.9.7-6.9.el6.noarch) has a option ROM (e1000-0x100e.rom), but it doesn't help.

Thanks!

Shawn

Firmware version on x520-SR2

webadmin@intel.com — Tue, 30 Apr 2013 15:20:37 GMT

Hi,

I have installed x520-SR2 on my Dell poweredge server running ESXi 5.1. I have configured this CNA with software FCoE

The driver version on the CNA is ixgbe 3.14.3. How can I find the Firmware version on the card?

I tried reading the release notes and checked the VMware website but couldnt find any helpful info.

~ # ethtool -i vmnic4

driver: ixgbe

version: 3.14.3iov

firmware-version: 0x61bd0001

bus-info: 0000:04:00.0

Can any one help?

SR-IOV on 82599EB 10G-Cards: Packets not filtered by MAC Address

webadmin@intel.com — Tue, 30 Apr 2013 14:51:45 GMT

Hi everybody,

we are trying to set up FPP using Intel's 82599EB 10-Gbit/s Cards.

Furthermore we are using the ixgbe driver version 3.14.5.

I am loading the driver using

modprobe ixgbe max_vfs=4,4,4,4

and bringing up the wanted virtual interfaces using

ifconfig <interface> <ip>/<suffix> up

But when sending packets to the interfaces from another machine, setting the destination MAC addresses of the packets alternating to the respective MAC adresses of the different virtual interfaces, all packets will nonetheless be captured by only one of those interfaces.

I checked with tcpdump on this interface, whether the received packets are actually carrying the different destination MAC addresses of my virtual interfaces on the targeted machine. And indeed they do.

Why now doesn't each virtual adapter receive exactly those packets carrying their respective MAC addresses as destination MAC address, but all are being captured by the very same virtual adapter, regardless of their MAC address?

Thank you in advance for your hints and best regards,

Richard

Intel 82579LM Gigabit Ethernet - UDP Packet Loss

webadmin@intel.com — Fri, 26 Apr 2013 19:06:52 GMT

I have a software application that runs on a laptop running Windows 7 SP1 which receives data at around 100Mbps via a UDP stream over a 1GbE connection. I've run the software on multiple laptops successfully in the past (older network adapters - e.g. 82577LM) . Recently I installed the software on a newer model laptop which has a 82579LM network adapter. When running the software on the laptop with the 82579LM adapter. With the 82579LM adapter I'm seeing approximately one lost packet every 25K-60K packets.

1. I'm running the version 16.7 (latest) of the Intel Network Drivers

2. Windows 7 - SP1 + latest updates

3. I've observed the same behavior on multiple laptop models by different vendors which contain the 82579LM adapter.

Searching the Internet I've seen some postings of issues under Linux complaining about similar 82579LM adapter issues:

http://www.mail-archive.com/e1000-devel@lists.sourceforge.net/msg04765.html

And some more here:

https://bugs.launchpad.net/ubuntu/natty/+source/linux/+bug/870127

Since this is running under Windows 7 SP1 we obviously have different drivers but I'm wondering if the issue is related. Any ideas for things I could try to fix the issue?

Thanks,

Ryan

How to disable Linux igb driver anti-spoofing

webadmin@intel.com — Fri, 26 Apr 2013 16:12:21 GMT

Anyone know if this is possible? I'm trying to get Resonate to work with a new Intel NIC and Resonate's tech support thinks that this feature is why their product isn't working. I'm hoping to avoid going out and buying a bunch of old Intel NICs that use older drivers.

Thanks.
