Problem:
Depending on the type of network card, they may or may not be automatically added to the hardware.
Solution:
When adding network cards, there are three cases that are handled in 2 different ways.
- Built-in network card:
It is automatically added to the hardware as it cannot be extended.
- USB adapter with its own MAC-Address:
Since the adapter can be unplugged and plugged into another device, multiple devices can have the same MAC-Address, that of the adapter and not the device itself, which can cause inconsistencies. Therefore, USB network cards are not automatically added to the hardware.
- A docking station:
For example from Dell, is a special case and is therefore not treated the same as a USB adapter, because it only works with pass through. This means it is only an extension of the built-in network card and does not have its own MAC address. The address is only forwarded from the actual network card. This is automatically added to the hardware.
