Authentication issues on ethernet port

[waqas]

Hi,
Is there an ETA on this ?

We've tried all possible options mentioned on web page but can not get it stick to one "driver key" or make it override mac for every driver key.

A quick reply will be much appreciated.

Hi

Yes, this is possible, but you need to set the MAC address in a different place, rather than per adapter, otherwise it will need to be set for every new dock you connect to.

The information on how to do this is on or support site. See the section 8.1 MAC address configuration options.

Thanks

Hi Wim,
Thanks for getting back, we've been trying the same web page but it has not helped.

There are basically 2 ways mentioned on the web page to enable MAC pass-through,

Opion 1)
GUI and registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}\XXXX Both essentially do the same thing but this setting reverts to default every time a new Dock is plugged.

Remote script push is not an option here as the laptop will keep creating new Driver keys for new docks and script is only one off.

Option 2)
Manual update of Registry key or Supplied script HKEY_LOCAL_MACHINE\System\CurrentControlSet\servic es\dlcdcncm\Parameters\

This option does nothing, we've tried on two laptops with latest Displaylink 8.3 driver and latest USB host driver with several docking stations and it made no difference.
we also updated registry key HKEY_LOCAL_MACHINE\System\CurrentControlSet\servic es\dlcdcncm_x64\Parameters\ but it did not help.


There is no displaylink customer service so We're trying to engage docking station vendor to get some support but it has not helped so far, issue is still open.

Thanks for your assistance here.

Hi

You want to use Option 2 and add the entry MacAddressOverride under HKEY_LOCAL_MACHINE\System\CurrentControlSet\servic es\dlcdcncm\Parameters\

I've just tested this on the latest Ethernet driver and it works fine. I used the MAC address you were testing with (EC21E5660A20). Note that this only gets read by the Ethernet driver when the driver starts, so you will need to unplug and replug the dock to get it to use the registry MAC address after you've set it.

Hi Wim,
Thanks for testing but unfortunately it still does not work for us.

We've even tried switching USB ports on laptops and power cycling the dock but no joy.

Attaching snippet of our latest test. Is there anything related to hardware /reg key that we might be missing ?

Thanks ,

I've exported the registry and pasted the .reg file contents below. The characters in the MAC address are all 0-F? A zero is not actually a capital "O"?

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\dlcdcncm\Parameters]
@=""
"MacAddressOverride"="EC21E5660A20"

How are you checking the MAC address? I'm using "ipconfig /all".

Hi,
Yes, the mac is all 0-F hex characters and we're checking by by ipconfig and getmac both.
