GS308T

This seems to imply that you can assign MAC-based VLAN (such as one not created on the switch) then add a port-based or protocol-based one.
Doubt there is any kind of Generic Attribute Registration Protocol (GARP) or Generic VLAN Registration Protocol (GVRP) allowing to automatically create and define VLANs. Nothing the like in the data sheet, the user manual. Neither implicit, nor explicit.
Yes, some competitors offer this feature on certain smart switch series. however, in the price range beyond of 200 Euro/port - not in the 10 Euro per port switch class we're facing here.
Keep in mind the GS308T is not a very advanced Managed Switch, much more a Smart Managed switch. Have requested a moderator to move your thread to the appropriate Plus And Smart Switches Forum intended to discuss Smart Switches (T) and Plus Switches (E), including Local and Remote Management models.

I don't know what either of those acronyms mean (other than looking them up :-), but I did quote from the switch manual and under MAC-based VLAN (pg.120) it also mentions This implies that you can configure a MAC address mapping to a VLAN that you did not yet create on the switch. The documentation on an HPE switch (that I do not own) says ...the port selects a VLAN for the frame in the order of MAC-based VLAN, protocol-based VLAN, and port-based VLAN... It would be helpful if the manual for the GS308T was as clear.
Thanks.
In my reading, the VLAN is created along when adding a MAC Address and a VLAN ID in an authenticated admin session - anything else would bring a massive security issue in absence of GVRP and GARP:
No idea if this UI would allow to define multiple MAC based VLANs for the same VLAN ID.
Well, I'm just yet another user here, and can be wrong. Yes, we have some deployed switches from a big competitor in the field, supporting GVRP and/or GARP. 8-)
I agree - I don't think the switch allows multiple MAC-based VLANs.
If I create a MAC-based VLAN, a Protocol-based VLAN and a Port-based, how would be a packet be tagged if it (in theory) qualifies for all three? I suspect it would be MAC, Protocol or Port; in that order. The switch manual is unclear, thus my request for a logic diagram.
