According to the Intel X550 datasheet (1), the controller supports IEEE 802.3az Energy Efficient Ethernet (EEE). It's also added as a key feature on the Intel's X550 Product Brief (2). However, it seems that 802.3az support has been silently dropped from the Intel X550-T1/T2 product brief (2) even if a product guide from Lenovo clearly mark this feature as supported. This feature is important for EE datacenters, especially for power-hungry 10GBase-T connectivity. We tried to get EEE working on X550-T1/T2 CNA on various switches without success. It seems this features is disabled or broken. PROSet 21.1 does not include any settings related to EEE.
Can you please give us the current status of 802.3az (EEE) on Intel's X550-T1/T2 CNA?
PS : Additionally, do you have an ETA for NBase-T support on these NICs? According to the product brief, this feature is marked as "to be enabled in a post-launch firmware release".

Thank you for posting your query in Wired Ethernet Communities.
I'm currently checking your concern and will update this thread as soon as possible.
You've mentioned trying various switches for your EEE implementation, kindly share the switch model and firmware version.
Here they are :
- Netgear XS708T - Firmware 22.214.171.124
- Netgear XS716T - Firmware 126.96.36.199
- DLink DXS-1210-12TC - Firmware 1.10.012
- Cisco SG350XG-2F10 - Firmware 188.8.131.52
Thanks for ur support.
Further checking, I am sorry to inform you X550-T1 require a driver to support EEE which currently we do not have the timeline for the driver release. And NBase-T is not supported in Windows but in Linux. Hope this clarified.
Apologize for any delay, further checking we would like to inform you NBase-T is supported at this point in Windows and Linux. However, there won't be support for .bz for X550 at this time and there is no plans to add it. Hope this clarified.
Thank you for the follow up, as mentioned earlier the X550-T1 require a driver to support EEE which we do not have the timeline for the driver release. I will further check also.
Althought the IEEE 802.3az is listed in product briefs below: https://www.intel.com/content/dam/www/public/us/en/documents/product-briefs/x550-ethernet-controller.... But there is a notation (1) next to it on page 8 stating: "Feature to be enabled in a post-launch firmware release". There is no timeline or update for the release, and this is the current status. Hope this clarified.
I'm here because like others I want to enable 802.3az EEE to reduce full time power&cooling. I wasn't able to get EEE working under linux (lastest version is 5.9.13).
/sbin/ethtool --set-eee enp8s0f0 eee on
Cannot get EEE settings: Operation not supported
Can you check if 802.3az is supported now?
Clearly support for power saving EEE mode was once intended, but the thing is it's been half a decade now. Is it safe to assume that nobody's working on this?
