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.
