Trunk with 3 tagged-1 untagged

RouterOS General

Hi,

I have a trunkport on my CRS that contains 4 vlans (vlan10-40) tagged.
One of the connected devices doesn’t work with tagged vlans.
The rest of the devices read tagged vlans perfectly.

I want to untag vlan40. But it still needs to be delivered by the same ether interface. Another interface isn’t an option in this case.
I did google a lot but cannot find a good answer. I think a Native vlan on the port should fix the problem but I read that this might not be possible.

What is the best way to deliver vlan10-30 tagged on ether5 and vlan40 as an untagged native vlan on the same ether5?

Kind regards,

Mark

I got this figured out by just removing vlan40 and assigning an IP address and corresponding dhcp server to the required ether port.

So I got ether2 with vlan10-20-30 and just assigned IP 192.168.40.0/24 and dhcp server to ether2. This results in a working situation. Don’t know if it’s recommended, but hey! it works.

Could you please post the relevant part of your config as I am looking to do the same, but I only can use on VLAN on my interfaces?

Thanks.
