Proxmox and vlan aware

[starnetwork]

Hello to Proxmox Community,
I have few servers with Proxmox ve 6 last version, working well with both internet and Internal Network
I try now to add vlan aware support, taking 2 servers, enabled the vlan aware checkbox on vmbr1 (Internal network) and reboot the nodes
after that, I go to 2 virtual machines and added vlan flag, but the communication btween this servers stop working, removed the vlan tag and it's back to work
the network settings:

Node1:
iface vmbr1 inet static
        address  192.168.1.11
        netmask  21
        bridge-ports enp3s0f1
        bridge-stp off
        bridge-fd 0
        bridge-vlan-aware yes
        bridge-vids 2-4094

Node2:
iface vmbr1 inet static
        address  192.168.1.12
        netmask  21
        bridge-ports enp3s0f1
        bridge-stp off
        bridge-fd 0
        bridge-vlan-aware yes
        bridge-vids 2-4094

now, some questions:
1. anything else I should do to make it work?
2. Should I stop and start the KVM / LXC after adding / edit vlan tag?

Thanks!

Hi,

what bind of NICs do you use?
What do you mean with?

but the communication btween this servers stop working,

The communication of the Guest works?
How are your Switch port configured?

Thanks for that response!
what bind of NICs do you use?
>> am using standard TCP communication and try to test with PING

but the communication btween this servers stop working,
>> communication on internal network between 2 KVM and LXC virtual servers work without the vlan tag, right after adding the vlan tag the communication is stop.

How are your Switch port configured?
>> no, what is the configuration I should do?

I guess your switch is dropping the VLAN tags.
Your switch must support trunk mode to pass the tags.
Or you have a simple switch that is not aware of VLAN in generall.

this switch support both Trunk and "Hybrid" modes
by default it's set on hybrid but I try to set it to Trunk
both not working
