It would be interesting to see if you could simply turn off VLAN
awareness in standalone mode, and still use unique pvids per port.

That doesn't work, just tested. When VLAN awareness is disabled,
everything is switched regardless of VLAN tags and table.

That's strange, do you happen to know where things are going wrong?

No I don't. I'll clarify with the hardware engineer.

I would expect:
- port VLAN awareness is disabled, so any packet is classified to the
  port-based VLAN
- the port-based VLAN is a private VLAN whose membership includes only
  that port, plus the CPU port
- the switch does not forward packets towards a port that is not member
  of the packets' classified VLAN

Me, too.

When VLAN awareness is disabled, are you able to cause packet drops by
deleting the pvid of the ingress port? Therefore, can you confirm that
lan1 is not a member of lan0's pvid, but the switch still forwards the
packets to it?

Will test.

Thanks,
