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 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? > Therefore, the implementation could look like this: > > * bridge without filtering: > * vlan_awareness=0 > * drop private vlans > * bridge with vlan filtering: > * vlan_awareness=1 > * drop private vlans > * standalone: > * vlan_awareness=1 > * use private vlans > * forbid other users to use private vlans to allow > configure_vlans_while_not_filtering behavior in .vlan_prepare() > * forbid use of lan0.<X> and lan1.<X> in .port_prechangeupper() > > So, this should work, or? Yes, this is an alternative that could work.
