Why no Wake On LAN for 10GbE NIC's?

I have several Intel Ethernet Converged Network Adapter X540-T1 NIC's and my main reason for purchasing them for for their iSCSI capabilities. I assumed that they could also support Wake On LAN since that feature in NIC's has been around now for over 10 years, so I didn't think to see if this was a capability. I need Wake On LAN for a particular project we have here at my company. I was wondering if this feature could ever be implemented through a firmware update in the future, or am I going to have to return these NIC's and go with another brand that does 10Gb and supports Wake On LAN.


Any ideas? Thanks for your help.

Intel Ethernet Connection I218-LM - Wake Up issues

May 12, 2014, 3:45 am

Hello,

 

We bought 6 new laptops with an I218-LM Ethernet card. (Dell Latitude E5540).

Everything works fine, excepted when the user is resuming from sleep mode or hibernation.

 

Using Wireshark, the PC is effectively trying to renew it's DHCP lease; our DHCP server is offering a lease, with no effect, and after 2 minutes, the NIC takes an APIPA address.

User have to disable and enable the card to get an IP back.

 

After some investigation, the problem occurs after installing SEP with NTP (firewall) feature, but we cannot find any event in the firewall log stating that something was blocked.

Of course, Symantec blames Intel's drivers....

 

I've tried every driver that was released recently, from the Dell and Intel websites, with no success.
I've tried to disable "Energy efficient Ethernet".

 

Going through Symantec support, I found this post which helped me somehow : http://www.symantec.com/connect/forums/sep-firewall-blocking-dhcp-request-i-think-after-sleep-or-hibernation

I've uninstalled the tools for the card management and reinstalled the driver alone (using the one that was unzipped in the temp folder).

It works if I uncheck the "Allow the computer to turn off this device to save power" box.

 

As my case is lost in Dell's infernal call centre loop, (they are replacing the motherboards every 2 weeks or asking me to reinstall the OS), I was wondering if you were aware of such issues with theses NIC's.

 

OS= Windows 7 x64 Pro SP1

Symantec=12.1.4013.4013

Drivers tested: original one (from 07/2013), 12.11.77.0, 12.11.96.1

 

Thanks for your attention!

Getting started with hardware timestamping and Ethernet frames (i350)

May 15, 2014, 2:02 am

Hi all,

 

I have a project where I want to timestamp all packets arriving on all four ports of an i350 device.  The system will be running Linux.

 

I found the igb driver and in the readme it says "The igb driver supports IEEE 1588 time stamping for kernels 2.6.30 and above.".

 

However, what I haven't found is documentation that explains how to enable timestamping and then actually use it.

 

1) Can someone point me in the right direction for a "getting started guide" or provide some tips please?  I've seen posts related to using ioctl calls to enable things but I'm assuming there must be some official documentation somewhere?

 

2) Is it possible to set the clock/counter used for timestamping packets after they arrive at the PHY from the Linux system clock?  The Linux system clock will be synched to IRIG-B.

 

3) I'll be capturing UDP packets.  What C/C++ based approach is recommended if I want to receive and examine the actual 14 byte Ethernet frames and CRC as well?  pcap?  raw frames?  The same approach should also allow examining the timestamp performed by the i350.

 

Many thanks for your help and time,

Ken

82579 Transmit hang with C200 and ME

Hello,

 

I have modified the current E1000 for a small embedded system. The driver works well on systems that do not have Intel ME. On systems that have Intel ME the transmit hangs. BTW the only systems I have tested with ME are C200 PCH boards. The problem could also be the result of differences between the C200 and C202.

 

On transmit I have verified that transmit descriptor head and tail pointer registers are correct after the driver loads up the DMA buffers but the MAC never sends the frames and never updates the head, and never sets the DD bit. This code works with other NIC's and on other 82579 NIC's. Receive DMA works fine.

 

I've had transmit hangs when the PHY throws data away, but when that happens the MAC updates the descriptors as though the packets were transmitted.

 

Is there something at the system level that must be running with Intel ME? I've gone the E1000 driver to find all ME specific code and I think I have included it my version.

 

BTW, I've also posted this on the E1000 driver forum, but no response yet.

Hello!  I've lost connectivity to my Dell Inspiron 530 after a move from Tucson to Austin.  While I realize I could have a hardware issue I'm trying to update the network adapter driver and see if that helps.  I have verified that my ethernet cable, router & modem are all in working order.  When I try to install Dell's latest driver (R154739) I get a message the message posted - "No Intel PRO network adapters are present in this computer".  In Device Manager, I see "Intel 82562V-2 10/100 Network Connections is enabled.  I checked the BIOS and it is enabled.  Last year I upgraded this desktop from the original OS Windows Vista (32 bit) to Windows 7 (32 bit).  Before moving to Austin, I had no problems with connectivity.  At this point, if anyone has any good ideas on how to further debug this problem they'd be much appreciated.  I am really looking for where I could get the latest Windows 7 driver for this network adapter.  Dell's website does not have a Windows 7 driver for this adapter given that it is part of an Inspiron 530.  HELP!  Thanks!

Problem with Wake on LAN - Cisco 3750 L3 Core ?

May 25, 2014, 11:20 pm

Two matters you may meet:

1.The Cisco L3 3750 switch (4 VLAN’s /interfaces–1 for each floor) – has NO access lists on it AT ALL. This new wake on lan config requires an access list to limit/the broadcasts to be from the sccm/wol server (i dont want broadcasts accross vlans other than the wol).

 

 

2.Does UDP port sccm use for WOL broadcast?

 

 

Solution:

 

 

For the question 1:

My concern is does an access-list not have an implicit deny (to all other traffic not listed) ? Answer: Yes it has (for directed broadcast, that is)

 

 

For the question 2:

Answer:I have not tryed with SCCM yet, but with Ghost we had a similar L3-switch-setup.

Why did Intel stop updating the 10GbE drivers for Windows 32bit

May 26, 2014, 2:36 pm

Every ProWin driver installer for 32bit since 18.7 has dropped support for PROXGB. The drivers are still included for 64bit. I understand that we are a rare customer that has some workstations running 10GbE to the desktop, but that does not mean that we are alone. We have workstations running both 32bit and 64bit Windows, and are having difficulty maintaining a consistent image across both OSs given this change. Is this an oversight, or is this a permanent change?

 

Hopefully some one has the answers....

Intel i350: promiscuous mode and SR-IOV

May 28, 2014, 12:24 am

Hi,

I'm using CentOS 6.5 VM on Xen 4.3 Hypervisor.

igb driver version is 5.0.5-k and igbvf driver version is 2.0.2-k.

 

I'm trying to enable promiscuous mode on the VM.

I configured a VLAN on a VF with 'ip link set ethXX vf xx vlan <id>'.

 

The VM uses that VF and when I checked if packets were received in the VM I found that broadcast packets and packets with the VM's MAC address destination were received.

But, packets with different MAC address destination were not received - promiscuous mode isn't working.

 

I tried to enable promiscuous mode in the VM with 'ip link set ethXX promisc on' and the packets were still not received.

 

Is there any other relevant command or configuration to enable the promiscuous mode?

 

Thanks!

Intel I350 Controller and Intel DPDK

I350 fails to sent packets in burst mode.

 

However it is possible to sent 1 packet at a time using the hardware.
Moreover.. it seems too slow on 100 and 1000 Mbps lines
On a 100 Mbps line it possible to sent only 6.9 MBps. Using Intel DPDK it should be able to achieve the line speed

 

I350 is being listed under the 'Supported NIC's' page on http://dpdk.org/doc/nics

This is the code I used


ret = rte_eth_tx_burst(port_ids[lcore_id], 0, m_pool, burst_size);

 

 

If I give a burst_size of 1. It works fine.
When I set it to 64 or 128, it fails.
I have allocated packets using

 

struct rte_mbuf *m_pool[burst_size];

 

for(j=0;j<burst_size;j++)   
                {           
                m_pool[j] = rte_pktmbuf_alloc(pktmbuf_pool);
                  }

 

all the mbufs were set to have

 

m_pool->pkt.nb_segs = 1;
m_pool->pkt.next = NULL;
m_pool->pkt.pkt_len = (uint16_t)74;
m_pool->pkt.data_len = (uint16_t)74;

 

 

Where am I going wrong ? But the same code works perfectly inside a VM

 

Any help would be appreciated.

 

Thanks and Regards

Wake on Lan issue with Intel CT network card.

Have an odd issue with WOL with an Intel CT network card. This is on a dedicated WMC PC. Everything with the WOL worked fine until I made a change. Since this is a dedicated Windows Media Center PC, and since I am using XBOX 360 as extenders, in order to improve the response of the extenders I changed the Speed & Duplex setting from "AUTO" to 1.0 Gbps Full Duplex.

 

This change made a huge difference in the response of the extenders, but now if the computer is allowed to sleep, it will no longer respond to a magic packet. If I change it back, then it will once again respond, but the extenders revert to their previous response time.

 

Anyone have an idea what would be a  fix for this? I know WOL works with the card and motherboard. I also tried 100meg setting and WOL worked, but the extenders response was terrible. The two options I currently have are to keep the setting on Auto or disable sleep. I really would like to keep the speed and figure out the WOL issue at 1gb full duplex. My system setup is below.

Fail to receive vlan traffic with X540 and SR-IOV

June 3, 2014, 5:21 am

On a server with an Intel X540 NIC adn SR-IOV enabled, I have a network configuration with

 

eth0 pf ---\

            \

              --- bond0 --- bond0.3001

            /

eth1 pf ---/

 

I can ping from bond0 to a connected host, but not from bond0.3001.

Packets are leaving the server and according to monitoring on the switch, reply packets are sent back, but the packet are not seen on the server (tcpdumped on eth0, bond0 and bond0.3001).

 

The strange thing is that the ping from bond0.3001 starts working when I add a vlan interface on one of the virtual functions

 

ip link set dev eth64 up

vconfig add eth64 3001

ip link set dev eth64.3001 up

 

This vlan interface can be created on the host system or on a virtual machine that uses one of the virtual functions of eth0. In both cases the ping starts to work and stops when the vlan interface is removed.

Could this be a bug in the driver?

 

The issue does not appear when SR-IOV is disabled. Then bonding and vlan interfaces on the bond work as expected.

Hello,

 

We are working on Dell-T1650 work station running on Intel Xeon E3-1240 v2,NVIDIA Quadro 410 512MB DDR3 is already installed on PCIe with IRQ 16.

 

Now, we have installed Intel's X-540-T2 NIC card on other PCIe slot on same PC. It shares IRQ 16 with NVIDIA graphic card.

 

Our problem is that we can't get NIC's better performance on same works station. So, we are planning to assign separate IRQs to both card.

 

How can we assign different IRQs to both card ??

Now, we have installed Intel's X-540-T2 NIC card on PCIe slot on same PC. It shares IRQ 16.

 

Due to Shared IRQ we can't get NIC's better performance in terms of lower latency on same PC. So, we are planning to assign separate or unique IRQs to NIC card.

I350-T4, 2012 R2, and VMQ

Cards in Slot1, 2, & 3 are all I350 cards.  There is a GUI / Powershell mismatch on whether or not VMQ is enabled.

 

I have enabled VMQ from the GUI via the device manager and by the Enable-NetAdapterVmq powershell command.  So in this instance, SLOT 1 Port 1, is the port I am referring to.  Enabling VMQ via powershell or by the GUI only affects the settings in the GUI.  Powershell still says enabled "False".  The check box in the Advanced settings / Virtualization settings unchecks and checks for Virtual Machine Queue within the GUI Properties of the NIC.  So the other thing is that SLOT 1 Port 3, a port on the same card says it is enabled in powershell.  Can anyone give me any insight into this issue and which setting I should believe?  I just installed 19.1 version of the intel proset.  I have a tendency to believe powershell over the gui.  Any insight would be helpful. Is there any service or anything I need to restart for powershell to show the change like the GUI does?

 

Last Question: is VMQ automatically enabled on a VMLB Team when used as an External Virtual Switch in Hyper-V 2012R2?  Note as you can see VMQ is disabled on all teamed NICs.

Intel 82599 ES SR-IOV vlan support

Hi,

Our topology is :

    Spirent <->Ubuntu 12.04 Server <-> our application  within VM where VF is directly attached.

 

on VF interface , created   vlan interface and spirent has also also vlan interface.

 

NIC : Intel 82599 ES

IXGBE Version : 3.15.1-k

IXGBEVF driver version :2.7.12

 

By default, VF is not receiving any packet , even ARP Packet.  After configuring vlan filtering from  VF, it gets packet  with stripped vlan tag.

 

There are couple of questions :

1. Is there any way to configure from VF, so PF doesn't filter any vlan , simply pass traffic to VF ? I checked Spec , it mentions about this and by default, it is enabled.

2. How to avoid stripping of vlan tag ? I  changed accrording to spec  but it  stopped receiving any vlan packet.

3. Even I tried to add all vlans(1 to 4094) , but it doesn't work. it looks like only fixed entries(most likely 8) can be added .

 

Please let me know how to fix this problem from VF side, can't change PF code.

Thx,

Atulya
