Hi,

 

We have many Intel X550-T2, and I have one genuine Intel X550-AT2 in our lab for testing.

 

The official standard for NBase-T is known as IEEE 802.3bz, and was promised as a feature-update via firmware by Intel, at the launch announcement within that X550 Product Brief, in this original Product Launch Intel file:  "Intel_Ethernet_Controller_X550_Product_Brief.pdf"

 

A few links to Intel's promise from Intel resellers:

https://www.uptimed.nl/downloads/uptimed-intel-x550-product-brief.pdf

http://8thgen.pillarglobalsolutionsinc.swcontentsyndication.com/sw/swchannel/CustomerCenter/document...

https://docplayer.net/55770857-Intel-ethernet-controller-x550.html


/quote/

"In addition, the X550 controller also supports NBASE-T* technology.
NBASE-T technology can increase network speeds of 2.5 Gb/s or 5 Gb/s using existing CAT 5e/CAT 6 cables at lengths up to 100 m.
Intel’s NBASE-T technology can be firmware upgraded to support the emerging IEEE 802.3bz specification(1).

NBASE-T Technology Support (IEEE 802.3bz "ready")
* Provides 2.5 GbE and 5.0 GbE link speeds over CAT5e/CAT6 cabling deployments. Firmware upgradable to IEEE 802.3bz(1)

(1) Feature to be enabled in a post-launch firmware release."

/unquote/

 

I also found this:

 

Filename: X550_SpecUpdate_Rev2.9.pdf

Quote, "NBASE-T speed advertisement (2.5 GbE/5 GbE) is disabled by default in the X550 NVM. An NBASE-T enabled driver should be used to link at NBASE-T speeds."

https://www.intel.com/content/www/us/en/support/articles/000030131/ethernet-products.html

 

Quote, "The Windows* drivers support the NBASE-T technology"

Indeed, yes I found that Windows 10/11 are now supported with NBASE-T 2.5/5.0 link speeds in Intel Driver pack Wired_PROSet_27.6_x64.zip

 

And:

https://www.intel.com/content/dam/www/public/us/en/documents/release-notes/ethernet-controller-x550-...

 

So.... the IEEE 802.3bz firmware "feature" upgrade from the draft Nbase-T, was promised by Intel in year 2015 (at Intel's x550 product launch) - And the IEEE 802.3bz standard was ratified in year 2016 - But, I can't find that firmware anywhere, now 6 years later in year 2022?

 

WHERE is the IEEE 802.3bz firmware, and what VERSION of the firmware added it?

HOW do we confirm if our older X550 NIC's have 802.3bz enabled?

Is IEEE 802.3bz integrated into an NVM image for X550; if so, which one and where is its release notes that specifically say 802.3bz now supported?

Or, is this IEEE 802.3bz added with an EEPROM update etc; if so how do I obtain it?

 

Note:  I've dug through NVM update release notes, and I do NOT see any specific mention of IEEE 802.3bz being "enabled" in the regular/mainstream NVM firmware.
If this feature-update for adding 802.3bz is in a NVM firmware, please give me the link to the Release Notes that specifically say it.

 

In general - Please provide details.

Thanks!

And, 802.3bz for x550 chipset is still promised here:

https://ca.ingrammicro.com/site/productdetail?id=A300-4048DX

"Intel's NBASE-T technology can be firmware upgraded to support the emerging IEEE 802.3bz specification."

But that was 6 years ago.

WHERE and WHAT firmware to install, to ensure IEEE 802.3bz compliance?

Thanks again!

Hi,

 

I am testing with Microsoft Windows 10 Enterprise version 21H2, and Windows 11 Enterprise version 21H2.

 

These operating systems are supported by Intel for NBase-T link speeds (2.5g/5.0g):

https://www.intel.com/content/www/us/en/support/articles/000030131/ethernet-products.html

 

I'm using these Intel drivers for Windows, the Release Notes also say it's supported:

https://www.intel.com/content/www/us/en/products/details/ethernet/500-controllers/x550-controllers/d...

 

However, I do not understand why the operating system matters?   I am asking about the X550 promised firmware update I linked (dated 6-years ago), to upgrade it from the preliminary/draft pre-standard NBase-T, to its official release final-standard IEEE 802.3bz?

 

Thanks!

Hello blogthis,


Thank you for the swift response. 


We asked the Operating System you used as it is stated on specifications of Intel® Ethernet Converged Network Adapter X550-T2 link below that NBASE-T support is in Linux Only

https://ark.intel.com/content/www/us/en/ark/products/88209/intel-ethernet-converged-network-adapter-...


You will also notice that the article mentioned that the Windows* drivers support the NBASE-T technology, but only in Autosense. 

https://www.intel.com/content/www/us/en/support/articles/000030131/ethernet-products.html

The Windows* drivers support the NBASE-T technology, but only in Autosense. 2.5GbE or 5GbE cannot be set as default, but if the signal degrades from 10GbE, it will automatically switch as long as the link partner supports those speeds.

On Linux* OS environments, the NBASE-T has been supported since NVM* version 1.55 and Linux ixgbe driver version 4.3.9.


It is also mentioned on Intel Ethernet Controller X550 Specification Update page 9 that Linux driver version 4.3.9 is currently the only supported software solution for NBASE-T.


NBASE-T Speed Advertisement

NBASE-T speed advertisement (2.5 GbE/5 GbE) is disabled by default in the X550 NVM. An NBASE-T

enabled driver should be used to link at NBASE-T speeds.

Linux driver version 4.3.9 is currently the only supported software solution for NBASE-T.

For future planned enhancements, contact your Intel representative.

Feel free to let us know if you have questions or clarifications and we will be glad to check on it.


Awaiting to your reply.


We will follow up after 3 business days in case we don't hear from you.

Hello,

 

To avoid further delay with your asking me for validation information like pictures and a YottaMark code to verify this Intel X550-T2 is not OEM, I'm providing it to you now in advance to prove this is a real Genuine Intel:

Hello,

 

I do not understand why you're so focused on Operating System?

You acknowledged what I observe, that YES: Windows and Linux are BOTH supported for NBase-T.

But, to reiterate again: This is IRRELEVANT to my request for the Firmware to support the emerging IEEE 802.3bz specification.

Also, you are quoting OUTDATED and DEPRECATED articles about X550....

 

Again - I am asking, just One (1) Question, for the 3rd time now:

Where is the promised Intel FIRMWARE for this X550 that upgrades from draft NBase-T to the standard IEEE 802.3bz?

 

In the Intel spec sheets that I quoted:

"Intel's NBASE-T technology can be firmware upgraded to support the emerging IEEE 802.3bz specification."

 

Just to avoid your confusion on my question - I have switched from Windows, and I am now using Linux (because Drivers and OS do not matter to this request!).

 

Now, where is the Firmware, and what version is that Firmware, to enable the Intel-promised IEEE 802.3bz specification on the X550-AT2 NIC?

 

Please reply with a Download Link to Intel's promised X550 Firmware to "support IEEE 802.3bz", and its Release Notes.

 

Thank you!

Hello blogthis,


Thank you for the patience on this matter. 


Please be informed that we received an update from engineering team that the X550 already support NBASE-T in Windows. The X550 does support NBASE-T in Windows, however it has a limitations that it does not support auto-negotiation for those speeds. This was changed in SW release 25.4, but can be manually changed to those speeds in device manager properties.


We have also requested the concerned department to modify the document (Spec Update) as it states that it does not work in Windows is incorrect.


Feel free to let us know if you have questions or clarifications. 


Awaiting to your reply.

Hello,

 

Thank you for informing me that the end-user has full supported control in Windows over setting 2.5g and 5.0g link speeds as of Windows Intel wired drivers release 25.4 (and higher). We had already observed this feature working in our labs.

 

However, again; That still does NOT answer my question. 

Let me try explaining the situation AGAIN, worded differently and spelled out:

 

NBaseT was a draft/pre-standard for 2.5g and 5.0g link speeds, that was 1-year later ratified as the official standard IEEE 802.3bz.

 

Intel promised a post-release firmware update to X550-T2 for upgrading the X550 using launch NBaseT draft/pre-standard, to the official IEEE 802.3bz standard. 

Note: IEEE 802.3bz has been the official ratified standard of 2.5g and 5.0 link speeds for over 5-years now.

 

I have linked and quoted the official Intel advertisements and documents above multiple times, that clearly promise in writing, that Intel would be upgrading from draft NBaseT to official standard IEEE 802.3bz support, post-launch of X550, as a free firmware upgrade.

 

So, my question, which I am RE-ASKING again for the FOURTH (4th) time:

I need from you with where to download, and how to apply, said firmware, with its written release notes showing clear confirmation, of exactly which Intel firmware update, upgrades NbaseT to add the official IEEE 802.3bz compliance, to the official Intel X550-AT2/X550-T2 cards.

 

Thanks (again).
