Hello,

I want to manage proxmox via the IP address 192.168.121.121:8006 and I want to set up multiple VLANs (different IP addresses) for other VMs. I still don't working proxmox management via VLAN.

Linux Bridge (vmbr0) without Linux VLAN (vlan100) - WORKING

/etc/network/interfaces
Code: 
auto lo
iface lo inet loopback

auto eno1
iface eno1 inet manual

auto eno2
iface eno2 inet manual

auto bond0
iface bond0 inet manual
    bond-slaves eno1 eno2
    bond-miimon 100
    bond-mode active-backup
    bond-primary eno1

auto vmbr0
iface vmbr0 inet manual
    address 192.168.121.121/24
    gateway 192.168.121.1
    bridge-ports bond0
    bridge-stp off
    bridge-fd 0

Code:

Thank you with regards Forse

In my defense, I studied:
12 forum articles
8 blog articles
5 watch youtube videos
1 proxmox networking documentation
Nothing helped. I'm desperate o_O
So I'm going to try one of my threads on the forum.
 
From where are you connecting to the management IP? Is the VLAN properly configured there?
 
I had the same experience. But after updating the linux network drivers of my network card (Mellanox) everything works fine without any change in the network config.
@proxmox: is it possible to update the Mellanox drivers to a more recent version in the installer-iso?
The content of my (working) network configuration:
auto lo
iface lo inet loopback

auto enp5s0f1np1
iface enp5s0f1np1 inet manual

auto bond0
iface bond0 inet manual
bond-slaves enp5s0f0np0 enp5s0f1np1
bond-miimon 100
bond-mode 802.3ad
bond-xmit-hash-policy layer2+3

auto Nfcs_nat_net
iface Nfcs_nat_net inet static
address 172.1.28.8/24
gateway 172.1.28.1
