Hi I have a 4 port LACP connected to a Proxmox host.

I set the ports at the switch to be at LACP. Everything seems to be ok, but I'm getting some disconnections from time to time.

At the side of Proxmox I configured it as LACP Layer3+4 before it was as Layer 2+3, but I used to see most of the traffic going just in one of the links. I understood that the mechanism for L2+3 only uses a secondary link if the traffic at any given time is higher than 50% of the capacity of the link (1000). So it doesn't have any real gain in terms of less latency or better usages of the 4 port.

Does my switch can work with L3+4 or only L2+3 ?

Thanks
