When connecting the eth1 port to my network switch I got an information from my router, that it assigned a new IP adress to the ethernet card with the MAC adress of eth1. So I assumed that it should be possible to reach that port via ping. This ping was done from a windows PC in my network. All four tries timed out. But looking to the result of ip a above, the IP adress is not shown on Linux side. This I did not see before.
The reason why I would like to use this second ethernet is because my workshop is in the basement of my house and the RaspberryPi is in a metal housing within a metal cabinet. Finally I like to use my devices hardwired instead of using WIFI. I thought it would be straight forward to put in an additional ethernet card, activate PCIe and then be able to use it.
Unfortunatelly I am not an Linux expert and I am not a native english speaker, so if I miss something from your advices please give me a hint. I will try to make it.
