Q-in-Q VLAN aware bridge (802.1ad)

[Blinkiz]

Hello.
Does anyone have a working linux bridge that is only handling 802.1ad packages (0x88a8)?
I can not get this to work. I do not know if my linux bridge config is wrong or if Proxmox is mapping a virtual machine on this bridge wrong.

Example of setup:

auto vmbr0
iface vmbr0 inet manual
    bridge_ports enp94s0f1
    bridge_stp off
    bridge_fd 0
    bridge_vlan_aware yes
    # Q-in-Q start
    up echo 0x88a8 > /sys/class/net/vmbr0/bridge/vlan_protocol
    up echo 1 > /sys/class/net/vmbr0/bridge/vlan_filtering
    # Q-in-Q end

Hi,

this config should work.

but also have a look on trunk mode in network section. I think this can also help.

man qm
