Did you mean "Access port"? On trunk port I'm expecting all the outgoing traffic to be tagged - and that' exactly what's not happening.

I keep investigating and it turns out that two ports with identical settings in the same VLAN are able to pass both tagged and untagged packets depending on what kind of host is connected (I have a Laptop and a Cisco3750 as hosts, untagged and tagged correspondingly).

It all looks and works like an AutoPVID feature, only there shall be no AutoPVID on the VSP platform and there is no way to disable it.
