[SOLVED] ProxmoxVE 8.2 don't tag vlans.

[adrin.maris]

Hello,

I just set up a Proxmox VE 8.2 server with a ZFS RAID 0 filesystem, but it seems that the VLAN tagging is not working correctly.

Here’s what I did:

1. I created a bond (bond0) between two physical interfaces (LACP, the networking infrastructure it's configure accordingly ).
2. I then created a bridge (vmbr0) with bond0 as the slave.

Using the vmbr0 bridge, I created a VLAN interface (vmbr0.200) and assigned it an IP address and a gateway.

When I tested with tcpdump -ni, I could see ARP requests and other traffic on bond0 and vmbr0, but not on vmbr0.200. This leads me to believe that the issue might be related to VLAN tagging.

I want to mention that I have two other servers with the same configuration, and they are working normally. Additionally, I have bridge-vlan-aware set in the configuration.

I attach the configuration below.

iface lo inet loopback

auto ens2f0
iface ens2f0 inet manual

iface eno1 inet manual

iface eno2 inet manual

iface eno3 inet manual

iface eno4 inet manual

auto ens2f1
iface ens2f1 inet manual

auto bond0
iface bond0 inet manual
        bond-slaves ens2f0 ens2f1
        bond-miimon 100
        bond-mode 802.3ad
        mtu 9216

auto vmbr0
iface vmbr0 inet manual
        bridge-ports bond0
        bridge-stp off
        bridge-fd 0
        bridge-vlan-aware yes
        bridge-vids 2-4094
        mtu 9216

auto vmbr0.200
iface vmbr0.200 inet static
        address xxx.xxx.xxx.xxx/24
        gateway xxx.xxx.xxx.xxx

What can I do? What I need to inspect ?
"ifreload -a " show no errors.

Thank you.

The bridge is already VLAN aware.
You do not need another bridge for the VMs.

You could create a VLAN interface bond0.200 and assign the IP to it.

Thank you, it works.
