Second ethernet card on Proliant Microserver N54l

[GIANCA65]

I'm trying to install a second ethernet interface on my Microserver Proliant N54l, but I'm facing some difficulties. Running LINUX )i've tryied with UBUNTU 20.04 and DEBIAN 10) I noticed that both enp2s0 and enp3s0 are renamed after eth0, which shouldn't happen. 

After configuring /etc/network/interfaces with my configuration and restarting the service, enp3s0 goes down. I have to manually bring it up again (ifup enp3s0).

After initial boot, dmesg returns:

root@servidor:~# dmesg | grep enp
[ 2.290238] r8169 0000:02:00.0 enp2s0: renamed from eth0

[ 17.378997] IPv6: ADDRCONF(NETDEV_CHANGE): enp2s0: link becomes ready

I loaded optimal settings on BIOS, but nothing has changed

As you can see, both interfaces enp have been named after eth0. I believe it should be one after eth0 and the other after eth1.

I replaced the card, but nothing has changed.

Is there any jumper configuration on motherboard? Or any other detail?

Thanks

Just adding more information, the ethernet card is PCI express

Hello,

Please do share the details of the card installed.

Also, was this working fine before?
