Lenovo T580 + Thunderbolt 3 Dock Mac Passtrough not working

2018-06-07, 15:07 PM

Hi,

 

we got several new Thinkpad T580 devices and Lenovo Thunderbolt 3 Docks. We using Thunderbolt 3 because we have to much trouble with the new UltraDocks for T580 (Video Dropouts). Everything works well except Mac Address Passtrough which is a big issue for us.

 

From the the Option Compatibility Matrix the supported Options on T580 is PXE Boot, Mac Address Passtrough, Wake on LAN. Mac Passtrough is activated in Bios. After Bootup i see that das Mac Adress is wrong and the device lands in the wrong Network/VLAN (Based on Mac Address). 

 

Whats wrong with this setup? is there no usable Docking Solution for T580? why is Mac Address Passtrough not working?

Sorry for the late reply, it works for us after installing the Drivers for the Thunderbolt Dock. The Drivers from Windows Update are not good enough.

 

Strange thing, i already deployed several T580/T480 without fiddeling around with Custom Lenovo Drivers and Mac Pass Through was no issue. Just a few new deployments fail and need Custom Lenovo Drivers.

Mac address passthru is also a bios settings in the t580. Are you using the most current bios version for the t580, and did you manually set the T580 BIOS setting for MAC address passthru to Enabled?

 

Also make sure you updated the drivers for the TB dock. New ones hit fairly recently.

 

Remember to only use TB cables marked with a thunderbolt, and be careful to plug the TB dock ONLY into the TB port labeled with a lightning bolt, NOT the USB C only port that looks like the TB port.

We are experiencing the same issue.  We have not been able to get these devices to PXE boot in Secure boot mode.

 

BIOS is current version 1.12.

BIOS settings are configured correctly.  

- MAC Address passthrough - Enabled

- Support for PreBoot Env Thunderbolt - Enabled

- Thunderbolt device - Enabled
