[SOLVED] Proper vlan setting in proxmox.

[Urbaman]

Hi,

I'm going to implement a trunk and some access ports on proxmox to the Cisco Switch in my homelab. Probably adding a bond or two but let's keep it to simple bridges for now.

I'm studying the docs and different guides on how to implement vlan trunks and vlan tagging, and I see mostly two ways for tagging.

The first is from the GUI.

1. I create the vlan-aware bridge on a nic, say vmbr0 with tags 10 and 100
2. I create a VLAN called vlan10, assing to the bridge as raw-interface, assign vlan tag, say 10, with proxmox IP on the "10" network.

eno0

vmbr0
    vlan-aware
    vlans 10, 100
    ...

vlan10
    address 10.0.10.11
    raw-interface vmbr0
    vlans 10
    ....

The second one is from the docs and the guides.

1. I create the vlan-aware bridge on a nic, say vmbr0 with tags 10 and 100
2. I manually add to the interfaces conf file a vmbrX.10 interface for tagging 10, with proxmox IP on the "10" network.

eno0

vmbr0
    vlan-aware
    vlans 10, 100
    ...

vmbr0.10
    address 10.0.10.11
    ....

Are the two methods interchangeable? Or do they serve different purposes?

Could I just create a vlan from GUI, naming it vmbr0.10, without raw-interface or tag, and that's it? The docs and the GUI are not so clearly

Thank you.

Here is what I have set under "Network"



And on a VM which I want to access vlan 20:



On the switch side, the interface is setup as a trunk port to the VLAN's I have configured.

Ok, but let's say I only have that phisical nic and I want to give proxmox an ip on vlan 10.
