    Confusion regarding trunking with 'VLAN aware'

    To make things crystal clear, I can reach devices in these ways: Host with VLAN aware enabled -> VM with vLAN defined inside guest -> VM with vLAN defined on NIC Host without VLAN aware enabled -> VM with vLAN defined inside guest -> VM with vLAN defined on NIC Host with VLAN aware enabled ->...

    Confusion regarding trunking with 'VLAN aware'

    Yep, I see a VLAN tag. Here's the trace of an example ping: From the source VM (VLAN configured in guest OS, VLAN not on NIC, VLAN aware not enabled on host): Out 1e:5b:03:0a:30:26 ethertype 802.1Q (0x8100), length 124: vlan 951, p 0, ethertype IPv6, fc00:b6d:cfc:951::6 >...

    Add default repository

    For the sake of testing, I configured a Proxmox Backup Server instance and installed the `proxmox-backup-client` on a Debian machine. Now, I'd need to add the Debian client to my Proxmox Backup Server instance. I specified a repository when logging in, but when I do not specify repository...

    Confusion regarding trunking with 'VLAN aware'

    I know all this. The functionality offered by VLAN aware (not removing vLAN tag when tagged inside guest) is active without VLAN aware being enabled. I don't understand why.

    Confusion regarding trunking with 'VLAN aware'

    That's what I expected, but with VLAN aware disabled, I can reach all VMs in the vLAN from all VMs in the vLAN; regardless of whether the tag is specified on the VM NIC or inside the guest OS.

    Confusion regarding trunking with 'VLAN aware'

    I know. Unless I don't understand your comment correctly, I'm not sure what this has to do with my post. My point is that not tagging the VM NIC, and specifying a vLAN inside the guest OS, should only work when 'VLAN aware' is enabled. But this has started working on all nodes after enabling...

    [SOLVED] OOMs and soft lockups while enough RAM and CPU is available

    This seems to be caused by a kernel issue (guest OS's). Topic closed.

    Constant Disk I/O (wondering if it's okay)

    It depends on the S.M.A.R.T. value provided by your disk vendor. If that value has always been 100%, there's probably no need to worry.

    Ability to use vLAN tag on other bridge than already configured bridge

    I know that is not possible. When I try to do that, I'm getting the error I posted. My question is if there's a good way around that.

    Ability to use vLAN tag on other bridge than already configured bridge

    I'm not sure what you mean. I am successfully stacking vLANs on top of the bridge's native vLAN.

    Ability to use vLAN tag on other bridge than already configured bridge

    Are you saying I wouldn't get this error if I enable 'VLAN aware' on vmbr999?

    Ability to use vLAN tag on other bridge than already configured bridge

    Situation: I have five bridges. Each bridge is used for a different vLAN. The vLAN is specified on the bridge ports. I want to replace these vLAN-specific bridges by one bridge, where I will set the vLAN tag on VM NICs instead of the bridge itself. Problem: to prevent downtime, I will update...

    'bridge_vlan_aware' requires reboot to take effect

    Hi, Yes, I understand rebooting is recommended, but from what I've gathered from docs, it should not be required. Hence my question: Why does 'bridge_vlan_aware' require a reboot to take effect? This does not seem like expected behaviour as it is not documented anywhere.

    'bridge_vlan_aware' requires reboot to take effect

    Hello, I enabled "VLAN aware" ('bridge_vlan_aware') on a bridge within Proxmox. I then clicked "Apply Configuration" for the configuration to be applied with `ifupdown2`. I would expect `bridge_vlan_aware` to be enabled, but `bridge_vlan_aware` is not enabled until after rebooting the Proxmox...
