If an untagged frame enters the transparent port,
the frame is discarded

If a tagged frame enters the double-tagged port, the port adds tag (VID is the double-tagged port default VID and PRI is the double-tagged port default PRI), and switches the frame to the transparent port

The transparent port transmits the frame unmodified (double tagged)

If an untagged frame enters the double-tagged port, the port adds tag (VID is the double-tagged port default VID and PRI is the double-tagged port default PRI), and switches the frame to the transparent port

The transparent port transmits the frame unmodified (tagged)
