Intel X550-T2 Card not compatible to HP 1950-24G-2SFP+-2XGT-PoE+ Switch

Hi,i have the following issue. i am using a workstation equipped with Intel X550-T2 card and connected both 10Gbase-T ports with a cat7 cable to switch-port 27/28. switch-port 27/28 are also 10Gbase-T capable.

 

only one port on the intel card will connect at full speed (10Gbps). the second port will run with 1Gbps. I tried these things:

 

- build up a lan-team on workstation-side in windows server 2012

- forced card- and switch-ports to 10Gbase

- build a aggregation with both switch-ports

nothing really helped. is there a compatibility problem between card and switch ?

i tried also to active and deactivate stp. i dont understand why only one port run with full speed.

i got a supermicro-mainboard based server in my office as well, two intel x550 onboard ports and the same problem occur. one port is at full speed the second port is at 100Mbps.

Hi Nebulaner,

 

 

Thank you for contacting Intel.

 

 

We would like to request for additional information. Please provide details below:

 

1. What are the speeds of the adapters without teaming configuration?

 

2. Which teaming mode did you configure?

 

3. Do you have link aggregation configured on the switch ports where the adapters are connected?

 

4. Driver Version:

 

5. System/Motherboard Model:

 

 

We look forward to your reply.

 

 

Sincerely,

 

Sandy

1. What are the speeds of the adapters without teaming configuration?

Without and with teaming both adapters work at the same speed at 1Gbps, autonegotation is on.

2. Which teaming mode did you configure?

i am using the windows server 2012 r2 default

3. Do you have link aggregation configured on the switch ports where the adapters are connected?

link aggregation is activated

4. Driver Version:

3.12.11.1

5. System/Motherboard Model:

Supermicro X11SSZ-TLN-4F

Hi Nebulaner,

 

 

Thank you for your information.

 

 

Please see below:

 

With regards to the adapter speed, are you trying to connect at 1Gbps or 10Gbps?

 

If you are teaming switch fault tolerance (SFT) mode, you don't have to configure link aggregation on the switch ports. Here what you need to configure on the switch:
  • Do not put clients on the SFT team link partner switches, because they do not pass traffic to the partner switch at fail.
  • Spanning Tree (STP) must be running on the network to make sure that loops are eliminated.
  • Turn off STP on the incoming ports of the switches directly connected to the adapters in the team, or configure ports for PortFast.
  • Only 802.3ad DYNAMIC mode allows failover between teams.
More information on Intel Adapter Teaming (ANS):

I hope this help fix your teaming issue.

 

 

 

Sincerely,

 

Sandy

Hi Sandy,

i dont get it to work. i configured all my settings like shown in your guide and i get the lan-team only working with 1Gbps, thats what autonegotiation want. When i try to force both adapter to full speed (10Gbps) only one team-member will hold his link. the second team-member get disconected. the 1Gbps lan-team works perfectly.

Is there anybody out there with the same card + switch ? i contacted hp, and they said "we cant help you with configuration-problems...." i dont think this is a configuration-problem. i think the switch and the network-card wont work with the full speed because of an incompatibility-issue.

Hi Michael,

 

 

I see that you are using Windows* Server 2012. As of the moment, we didn't have driver for this operating system yet. However, allow me to further check on this.

 

https://downloadcenter.intel.com/product/88209/Intel-Ethernet-Converged-Network-Adapter-X550-T2

 

 

For troubleshooting purposes, can you try on supported Windows* system (Windows* 7 or 8) so you may install the drivers. We look forward to your test results.

 

 

Sincerely,

 

Sandy

Hi Michael,

 

 

Please check if you have the "legacy switch compatibility" settings in Adapter's Advanced Settings. if you have this, try enabling this feature.

 

 

We look forward to your test results.

Hi Michael,

 

 

I would like to check if you are able to resolve the network connection problem.

 

 

Please let us know if you need further assistance. We suggest to also check with switch support for any recommendations for switch port configuration.

 

 

Sincerely,

Hello Sandy,

i can´t find the setting "legacy switch compatibility". i got a new eeprom from supermicro support i contacted before. i will try this and can you tell me when i can expect a full windows server 2012 driver-support ?

Hello Michael, Hello Sandy,

i have exactly the same issue.

 

Only difference is the used system Windows 2008 R2 Server and we have the 48 port version of the hp switch

The two adapters run both with 1Gbit/s - but not with 10Gbit/s

I am curious about a solution!

Best regards

Christian

Hello Sandy,

Not all systems have this setting. You can find this in Device Manager -> Adapter Properties -> Advanced tab

 

 

 

***************

 

 

Please try to install the driver for this adapter. The latest version is 3.12.11.1. This version has support for Windows* 2008 and 2012. However, it would be best if you can request and isntall the tested driver from your respective system manufacturers to avoid any compatibility problem.

 

 

If you choose to try out our driver, you may download it here:

 

https://downloadcenter.intel.com/product/84329/Intel-Ethernet-Controller-X550-AT2

 

Filename: 21_0_cd.zip

 

Version: 21.0

 

 

We look forward to your test results.

last but not least i solved the case by my own - i force the switch Michael uses too to drive the port with 10 gbit/s

through the management of the switch.

 

Now the driver shows the higher speed to on the server.

Done - have a nice weekend

Hi,

i tried to set the port-speed on both ports to 10Gbps in the switch-management, just one of the two ports will accept this speed. the second port is disconnected.

did you just forced the port-speed or did you add some more settings to the switch management ?

Hi Christian,

 

 

Thanks for the updates glad to know that you were able to connect at 10 Gbps.

 

 

As for Michael's case, he was trying to configure teaming. But, he is getting 1 Gbps on one of the ports when connected to the switch.

 

 

Hi Michael,

 

 

Do you have other 10 Gbps switch that you can test? Or try connecting to other ports.

 

 

Sincerely,

 

Sandy

Hi,

i bought a qlogic qle3442-rj-ck dual port rj45 10gbps card, put it into my system, boot it up, installed all driver and it worked without adjusting or touching any setting.

please intel i need a fix, i have already spend 400 € for a second 10gbps just to test that your nic is the problem....
