I have setup a vlan on ether5 which is attached to another MT router on that port with the same vlan setup and id. The pings go through, but I can’t see the vlan id. Should they be displayed? I can’t see the vlan id in torch on the other side either.

you have to check the vlanid option
It turns out that you can’t see the vlan tag when you torch the vlan interface. You will have to torch an interface that is connected on the otherside of the vlan interface.
