PVID 3 as the native VLAN ID, enables GVRP, sets the GARP timers,

Configuring Private VLANs

Private VLANs provide port-based security and isolation between ports
within the assigned VLAN. Data traffic on downlink ports can only be
forwarded to, and from, uplink ports. (Note that private VLANs and
normal VLANs can exist simultaneously within the same switch.)
