SOLVED: Can't assign a VM to VLAN 1 even when I believe the vmbr is set up correctly?

[jlficken]

The switch ports are set up as trunk ports with VLAN5 being untagged (where I want most VM's to land) and VLAN1, VLAN25, VLAN75, etc being tagged.

Here's my network.cfg:

auto bond1
iface bond1 inet manual
        bond-slaves enp133s0 enp4s0d1 enp5s0f1
        bond-miimon 100
        bond-mode active-backup
        bond-primary enp133s0
#VMs

auto vmbr1
iface vmbr1 inet manual
        bridge-ports bond1
        bridge-stp off
        bridge-fd 0
        bridge-vlan-aware yes
        bridge-vids 1-4094
#FSPVE2-VMs

I've restarted the node.

I've tested tagging the VM with a different VLAN that is also set to tagged on the switch port(75 in this case) and with DHCP being enabled on the VM it lands on the correct subnet, however, I can't for the life of me get VLAN1 to work on vmbr1.

Does anyone have any thoughts as even though I know that using VLAN1 isn't recommended it's my understanding that it should work?

Hi, I would guess because vlan 1 is default PVID on interface:

auto vmbr0
iface vmbr0 inet static
    address 192.168.14.243/24
    gateway 192.168.14.1
    bridge-ports eno1
    bridge-stp off
    bridge-fd 0
    bridge-vlan-aware yes
    bridge-vids 2-4094

root@z:~# bridge vlan show | more
port              vlan-id 
eno1              1 PVID Egress Untagged
                  2
                  3

maybe you can change this with command

bridge vlan pvid/untagged

I wound up going into the switch ports being used for my VM's and changed the way they were configured.

I have VLAN1 set to be *Untagged* now and the rest of my VLAN's are now *Tagged*.

In the NIC setup for each VM/LXC on Proxmox I set all VLAN ID's now except for 1 since it's now Untagged on my switches and everything is working correctly.
