Dear Community,

I'm struggling with setting-up the VLAN Trunking to VMs.
I'm running on Proxmox 8.1.3 with a cluster of 3 nodes (DELL Server)

I've an Allied Telesis switch, with this config:
Code:
interface port2.0.4
 description "PVE-LAB-01 Trunk"
 switchport
 switchport mode trunk
 switchport trunk allowed vlan add 9,37
 switchport trunk native vlan 4000
 rmon collection history 14 buckets 13 interval 300 owner RMON_SNMP

Here is the network configuration of the node 1 (where the VM is running)

The VLAN 9 who is used for the mangement is working fine. It uses vmbr0 who is a bridge of the network adapter connected to the switch.

The issue start when I try to tag the VLAN to a Virtual Machine.

The VLAN 37 is not working inside the VM. I've tried the VLAN 37 as native vlan and it's working fine.
I've tried with VirtIO network device -> Not working
I've tried with Linux Bridge with Vlan Aware -> Not working

Perhaps I've tried with the network adapter Eno1 and I was able to retrieve the VLAN in the VM.
But I don't want to use eno1 & eno2 as they are 1gbs network adapter.

Some info about the network adapter:

eno1 & eno2: Broadcom Gigabit Ethernet BCM5720
ens1f0np0 & ens1f1np1: Broadcom Adv. Dual 10GBASE-T Ethernet

Many thanks in advance for you help.
