Bond on VLAN's

[SudsMaker]

I am hoping someone can get me past this hurtle.
I have 4 NICs with 2 on different VLANs.

So NIC's 1 & 2 will be on VLAN50 (Management)
NICS 3 & 4 will be on VLAN100 (Virtual Machines)

I have tried to understand the documentation but something's just not sinking in for me.
https://pve.proxmox.com/wiki/Network_Configuration#sysadmin_network_bond

Attached is the config where I tried to setup 2 VLANs with the NICs.
I do not have a switch that supports LACP.

Any help would be great.

Hi.

You're trying to setting up VLAN on physical NIC, you should before set up the bond and then configure the VLAN over it.

Something like this:

# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage parts of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!

auto vmbr0

    address 192.168.100.4/24
    gateway 192.168.100.1
    bridge-ports bond0.100
    bridge-stp off
    bridge-fd 0
# Bridge on VLAN 100

auto vmbr1
iface vmbr1 inet static
    address 10.10.50.4/24
    bridge-ports bond1.50
    bridge-stp off
    bridge-fd 0
# Bridge on VLAN 50

source /etc/network/interfaces.d/*

Be carefoul about the gateway of vmbr1 that is not on the same network of the bridge and in any case you cannot assign multiple default gateways (you have already set up gateway for vmbr0).
Usually you don't assign an IP address to Proxmox nodes on VM bridges (of course if it is not required for some other reasons).
You don't need "bridge-vlan-aware yes" beacause VLAN aware bridges are used when you want to tag the VLAN on the VM (not your case).

Why you choose to tag packets if you don't have multiple VLAN on the same interfaces?
Shouldn't be easier to set up the ports on the switch in access mode with untagged VLAN?

Thank you, I think it finally got it.
