Hello,
I've installed Proxmox VE on a server with four Broadcom BCM5709 NICs and configured the bonding via the webinterface. The /etc/network/interfaces looks like this:
On the switch I have this configuration:

I've installed Proxmox VE on a server with four Broadcom BCM5709 NICs and configured the bonding via the webinterface. The /etc/network/interfaces looks like this:
Code:

On the switch I have this configuration:

On the switch I'm getting these messages:
