MAC Address Pass-Through
This feature replaces the external NIC MAC address (in a
supported dock or dongle) with the selected MAC address from
the system. The default option is to use the Passthrough MAC
Address.
When the Integrated NIC option is selected, we recommend one of
the following:
• Disable the integrated NIC in the BIOS to prevent any issues
from multiple NICs on the network with identical MAC
addresses.
• If the Integrated NIC cannot be disabled, do not connect it to
the same network as your dock or USB Ethernet dongle.
