Here I found a similar problem, but without a solution.
https://forum.proxmox.com/threads/proxmox-ve-bond-with-802-1q.30133/
In my old setup I have previously a proxmox 3.4 over 3 years running fine with LAG on two nics to a Netgear GS116ve2.
In my old setup under 3.4 I had no Layer options defined, under 5.1 I testet both. (2+3,3+4) without difference.
On the managment web from switch I see very low receive traffic on nic2, the send traffic locks normal.
the LAG is on Port 2+3
What are the main problems:
- I can´t ping my gateway
- apt-get update sometimes works sometime its stopping somewhere.
- proxmox web is working but slow. NOVNC and console is working with the vm´s
- all server 2012r2 have no network (although it´s connected, less traffic is visible), AD is not available, RDP is not possible
If i disconnect lan 3 all works, network is in normal state again.
has no result.
my network config:
Does someone have an idea what´s going wrong and has change between 3.4 to 4.4 where the problem beginns?
Edit:
After my last reboot, it looks like with layer 2+3 it´s working. But the ping from proxmox to 192.168.100.254 (Gate) is still broken and I can only reach by rdp my DC but not the Exchange Server and nas. Maybe only luck, over which nic the communication of the DC is going?
