VLAN support on pimox7

[bronkoo]

Hi,

given by the fact 'vlan' package isn't installed by 'RPiOS64-IA-Install.sh' script I tried to do it, but this will remove 'proxmox-ve' and 'pve-manager' packages... I need to add VLAN's on my eth0 for untagged interfaces on CT's, as normal I think...

Best.

Yes, at first. But 'VLAN Tag" is grayed out in ->Network ->Create ->Linux Vlan That's why I've checked 'vlan' package...

kernel has vlan support:

Did you create a Linux bridge first and activate VLAN awareness then then or otherwise? Because I can activate it.

Ok, thanks. Just stumbled over: Default Bridge 'vmbr0' works without any changes - 'VLAN aware' is unmarked - and simple configure the 'VLAN Tag' in network device for my CT's. Like KISS...

Not an issue currently, but 'VLAN Tag" is still grayed out in ->Network ->Create ->Linux Vlan.

afaik you need to create a linux bond before you can create a linux vlan. Read the manual, I guess its described like this.

sorry in the hell ;-), but that doesn't make sense... RTFM for sure.

Hi. For me activating the vlan aware feature on the bridge in the gui and then rebooting causes me to lose access to the pi and requiring me to start again from scratch with a reinstall. Tried a few times.

I don't get this issue on my other non pi nodes full proxmox clusters.

Any ideas.

The vlan aware feature is a kernel compile option which the standard pi kernel doesn't enable. You can try this custom kernel which does have it enabled (see https://github.com/pimox/pimox7/issues/28)

Also you may be able to do what you want with openvswitch-switch package.

Just to add our trickery to get vlan-aware working, might not apply to your case. We needed to set our nics in promisc mode. Sounds like a bug. :)
