Good day,

I am fairly new to proxmox and i want to use another NIC for our lab VLANS when we create VM's on proxmox however the other 3 ports even when a fly lead is connected the ports are not coming up... I am not sure if the ports are disabled somehow by default. I cannot seem to get them in a UP state. Please see screenshot attached/below.

Any help or suggestions would be appreciated... I tried some basic try another fly lead and changed port on the switch where it connects to but still the ports are not active. I can SSH to the server and you can see below the interfaces config...

Just had to install the Debian net tools package and I then just used the ifconfig (interface name) up command
