VLAN Aware Bond0 not working

Hello,
there must be something wrong with this, although I believe it should be working, it is not.
To my understanding, in PVE, I create a LACP-Bond to the switch, using Linux Bond. (802.3ad)
Then I created a Linux Bridge, which is VLAN Aware and bound to that bond0.
Then I give a VM that Linux Bridge, and tag it appropriately.
And that should be it.
However, the VM can't reach the switch.
On the switch itself I have tagged all VLANs, and set the VLAN 33 to PVID, so that I can reach the IP of the PVE on the main Linux Bridge.
Note that I am currently using everything over one double-10G NIC, so that is why "VMs" Bridge has the management IP. I could separate that if required.

This is the config in the PVE:
Code:
auto lo
iface lo inet loopback

iface eno1 inet manual

iface eno2 inet manual

iface eno3 inet manual

iface eno4 inet manual

auto ens2f0np0
iface ens2f0np0 inet manual

auto ens2f1np1
iface ens2f1np1 inet manual

iface eno5np0 inet manual

iface eno6np1 inet manual

auto bond0
iface bond0 inet manual
        bond-slaves ens2f0np0 ens2f1np1
        bond-miimon 100
        bond-mode 802.3ad
        bond-xmit-hash-policy layer2+3
#LACP-Bridge-to-CSW

auto VMs
iface VMs inet static
        address 10.xxx.33.62/24
        gateway 10.xxx.33.254
        bridge-ports bond0
        bridge-stp off
        bridge-fd 0
        bridge-vlan-aware yes
        bridge-vids 2-4094
#Virtual Machines VLANs

My main problem is that my VM that gets that "VMs" Bridge (but tagged VLAN32) can't reach the core switch, which is in the same VLAN.

Ideas where I am thinking wrong?

Thanks
 
Finally managed to solve it. It was actually not Proxmox's fault. It was actually our switch that prevented proper functionality. Finally, when we cleaned up the switch, Proxmox started working as it should.
