vmbr0: received packet on eno1 with own address as source address (addr:xx:xx:xx:xx:xx:xx, vlan:99)

[jhr]

Hello,

I am strugling with vlan settings on one Proxmox VE (strange, but other PVEs runs without this error and all PVEs are configured in the same way).
My config:
auto lo
iface lo inet loopback

iface eno1 inet manual

iface eno2 inet manual

iface eno3 inet manual

iface eno4 inet manual

auto vmbr0
iface vmbr0 inet manual
bridge-ports eno1
bridge-stp off
bridge-fd 0
bridge-vlan-aware yes
bridge-vids 2-4094

auto vmbr0.99
iface vmbr0.99 inet static
address 192.168.99.103/24
gateway 192.168.99.1

But from time to time I get error message:
[ 5543.956575] vmbr0: received packet on eno1 with own address as source address (addr:xx:xx:xx:xx:xx:xx, vlan:99)
[ 5549.962877] vmbr0: received packet on eno1 with own address as source address (addr:xx:xx:xx:xx:xx:xx, vlan:99)
[ 5573.733222] vmbr0: received packet on eno1 with own address as source address (addr:xx:xx:xx:xx:xx:xx, vlan:99)

[ 5737.661356] vmbr0: received packet on eno1 with own address as source address (addr:0c:c4:7a:cd:6b:ac, vlan:99)

Any tips ?

Is the host connected to a switch? Does this switch know about the VLAN?
Are the other hosts connected to the same switch?

Which NIC model do you use here? Does it run the latest firmware?

I've only seen those log entries when a bond with `balance-rr` was used without switch support, which shouldn't be the case here based on the network configuration.

Yes, the host is connected to a Mikrotik switch with vlan support.
Well, the other hosts are connected to another Mikrotik switch, but all vlans are configured on all switches, but I can arrange move this host to the same switch. This could be useful tip.

It seems connecting PVE to different switch solved this problem. I don't understand why, but thanks for suggestion.
