mtu 1500 qdisc mq state DOWN

[salem mubarak]

Hi there, I have a small issue with the Proxmox configuration. How can I solve it?

vmbr0 is down because eno3 is down, eno3 is down because of "no-carrier", so no physical link is detected.

Thank you for your reply
physical I have two connections between the server and switch, one Ethernet and the other fiber optic, but I don't know what the problem exactly is.

do you mean 2 interfaces on the server connected to 2 ports on the switch ?

if yes, you need to create a bond interface on proxmox side (active-backup for example). Because, if not, you'll have a network loop. (and maybe if you have spanning tree enabled, it'll cut one of the link).

can you share your /etc/network/interfaces ?

Yes sure,
I don't know if it is the correct configuration or not because I don't have more expire on the CLI command.
if it wrong please provide me with correct config.
