Every frame received by the switch is classified to one VLAN. There are two ways in
which frames are classified to VLANs:

Untagged frames are classified to the VLAN associated with the port on which the
frame is received (Port-based VLANs).
❒
Tagged frames are classified to the VLAN identified by the VLAN tag in the tag
header of the frame.
