Proxmox 7.1-2 bond network interfaces down :(

[ManuelDev]

I have proxmox 7.1-2 installed on a dell powerge R710.
I create a bond with two of the network interfaces and register it on the switch. Until here everything of the most trivial...
After restarting the server I see that all the network cards are inactive. I try to bring up the network service again with a

systemctl enable networking; reboot

The server restarts but the network interfaces are still down...
What is happening ? Why do network interfaces not wake up after bonding? Any idea how to proceed to bring up the network interfaces again in porxmox...

here is my setup /etc/network/interfaces

Manually removing the bond0 in /etc/network/interfaces and restarting the network service everything is back to normal.
How should I create the bond so as not to suffer this inconvenience?

Apparently creating a bond in proxmox is not as trivial a task as it seems.
What am I doing wrong?

i make a new bridge to allow proxmox assign to a vm, eg: vmbr1 with his bridge port to bond0

The bond0 port is not assigned to any machine. The network will communicate with the iSCSI server to provide the storage.
It's already solved by marking the hash policy as layer 2+3.

I have no idea why this is so, but it solved my problem.
