Bridge VLAN-aware doesn't work only on one of my nodes.

[sa10]

Hello,
Maybe anyone has any ideas how to find the cause of a non-working vlan with bridge in the VLAN-aware mode.
It doesn't work on just one of several nodes. All nodes has same configuration and the same hardware.

I have two vm in vlan147 :
VM-1 xx.xxx.191.4/24 node2 (pve-manager/6.4-14/15e2bf61 (running kernel: 5.4.174-2-pve))
VM-2 xx.xxx.191.101/24 node4 (pve-manager/6.2-11/22fb4983 (running kernel: 5.4.60-1-pve))
The vlan147 came to nodes as tagged traffic
VM interface for example :
net0: virtio=16:08:22:91:0A:9A,bridge=vmbr0,tag=147

I run inside VM2
ping xx.xxx.191.4
And tcpdump sees on the bond0 (eno1-eno2) of the node2 ARP Request and Reply which come from VM-1:

6), IPv4 (len 4), Request who-has xx.xxx.191.4 tell xx.xxx.191.101, length 28 23:16:10.713871 e2:a7:6f:a4:df:5f > 16:08:22:91:0a:9a, ethertype 802.1Q (0x8100), length 64: vlan 247, p 0, ethertype ARP, Ethernet (len
6), IPv4 (len 4), Reply xx.xxx.191.4 is-at e2:a7:6f:a4:df:5f, length 46

But it doesn't see the Reply on the bridge vmbr0, only Requests
The VLAN-aware is on.

My nodes have different version of proxmox, the problem node is under pve-manager/6.4-14/15e2bf61 (running kernel: 5.4.174-2-pve

What could be the reason?
Thanks!

I found the reason, now everything is working well.
I found these files in the procfs,
ls /proc/net/vlan/
bond0.147 config
I didn't find the bond0.147 in the configs or in the command history. How this was created it’s a mystery of course .
I have executed this command to remove this interface
ip link delete link bondname 0.147 type vlan id 147

it's look like a vm was started once with setup in non-vlan aware config. (so proxmox creat a bond0.147 && vmbr0v147 in background at vm start).
it's not delete on vm stop.
