CR112 dot1q trunk for all tags

Hi,

I’m using a CR112 as a basic switch (no IP or routing etc) and just want all the ports configured as dot1q tag trunks, and to forward on any tag received without filtering. But obviously not to propagate traffic between tags. So for example, traffic that is tagged 75 is received and dispatched and traffic stays on tag 75.

I’ve been through the online examples a bunch of times, but there doesn’t seem to be an obvious way to achieve this.

Any help would be much appreciated!
