Network card

[rcarvalho]

Hi there.

A few years ago i had a quick experience with Proxmox (around version 4) and now i've returned

I've setup an old Fujitsu Primergy RX300 S6 with Promox and it's running ok, however i'm having some issues with my network card.
It's a 2 x Gigabit card and when i installed Proxmox, i had only Lan 1 active on BIOS.

Now i'm trying to get it running with both Lan Ports but when i activate both Lan Ports on BIOS (it only allows Lan 1 or Lan 1 and Lan 2 ative) , Proxmox start with both interfaces down.

If i try to get the interfaces up manually trough command line, it apears to be ok, but no connection.

I've tryed boot the server with a live Hirens usb, and both Lan Ports works.

Anyone has a clue what could be the issue?

Thanks in advance

With both LAN ports enabled in BIOS, what is the output (on the Proxmox host console) of:
ip r
ip a
cat /etc/network/interfaces

Thano you for fast reply and help

Here it goes:

ip r

When both LAN ports are enabled the devices are named enp8s0f0 and enp8s0f1, while the old device was named enp8s0 (when only LAN1 was enabled). Just change the old name in /etc/network/interfaces with the new name for the LAN1 (add f0 to both occurences) and reboot.

Thank you very much.
It's working fine now.

Best regards

I'd also recommend to bond the two devices together, you then can plug in what you want.
