Hi, I'm having some issues with interface bonding. I have four interfaces on my server (running Proxmox VE 6.3-3).
The network config summary is as follows;
- vm1 -> vmbr0
- vm2 -> vmbr0
- vm3 -> vmbr0
- vm4 -> vmbr0
- vm5 -> vmbr0
- vmbr0 -> bond0
- bond0 -> enp4s0f0 enp4s0f1
enp* are physical interfaces.
I have tested with all four network interfaces bound to bond0 (enp3s0f0 enp3s0f1 enp4s0f0 enp4s0f1), but that doesn't work either.
All interfaces are "active" and have "autostart" enabled.
All VMs can reach the "outside" internet, but they can't always reach each other.
Tracepath does finish from given VM to another one, but with ~2-3 second delay.
When a VM is unable to reach another one, it's unable to ping or reach it by any means, while the tracepath still does finish.
As soon as I switch the vmbr0 slaves from bond0 to any physical interface (eg. enp3s0f0) the connectivity is perfectly fine.
The switch that all four interfaces are connected to is a "HPE V1910-24G Switch JE006A" (in case anyone knows that these have any issues.. ?). Operating as a "dumb" switch.
