When using IEEE 802.1Q port-based VLAN classification, all untagged
frames received by a port are classified as belonging to the VLAN whose
VID (PVID) is associated with that port.
When MAC-based VLAN classification is enabled, the source address of
untagged ingress frames are checked against the MAC address-to-VLAN
mapping table. If an entry is found for that address, these frames are
assigned to the VLAN indicated in the entry. If no MAC address is matched,
the untagged frames are classified as belonging to the receiving port’s
VLAN ID (PVID).
