If a tagged frame enters the untagged port, it is
switched to the tagged port
If the tagged port is not a member of the frame VID, the
frame is discarded
If the tagged port is a member of the frame VID, the
frame is transmitted unmodified (tagged)
• If a tagged frame enters the tagged port,
which is not a member of its VID, the frame
is discarded
• If a tagged frame enters the tagged port,
which is a member of its VID, the frame is
switched to all other members
The untagged port removes the tag and transmits the
frame untagged
If an untagged frame enters the untagged port, it
is switched to the tagged port
• If the tagged port is not a member of the untagged
port default VID, the frame is discarded
• If the tagged port is a member of the untagged port
default VID, the tagged port adds tag (VID is the
untagged port default VID and PRI is the untagged
port default PRI), and transmits the frame tagged
If an untagged frame enters the tagged port,
which is not a member of its default VID, the

If an untagged frame enters the tagged port,
which is a member of its default VID, the frame
switched to all other members
The untagged port transmits the frame unmodified
(untagged)
