Hi all,

We use Proxmox VM 8.3.0 cluster with 2 node machine. We have 10Gb ethernet card and 1Gb ethernet card on 2 node machine. We create linux bridge over 10gb ethernet card.

Every node machines have network traffic drops. We checked whether there was any packet drop on the switches. There is no drop visible on the switches .
Thinking that traffic drops might be caused by an error on the Linux bridge, we set up two machines to communicate via 1Gb ports. We configured the VM servers to access the internet via a 10Gb Linux bridge. However, this did not resolve the drops.
Could this be due to a configuration error on Proxmox? We can't understand why there is a traffic drop.


Our 10GB ethernet card model is Mellanox Technologies MT27710 Family [ConnectX-4 Lx].

1 GB ethernet card models;
Broadcom Inc. and subsidiaries NetXtreme BCM5719 Gigabit Ethernet PCIe (rev 01)
