Ingress Egress
If a double-tagged frame enters the transparent
port, it is switched to the double-tagged port
• If the double-tagged port is not a member of the first
VID of the frame, the frame is discarded
• If the double-tagged port is a member of the first VID
of the frame, it removes the firs tag and transmits the
frame tagged.
If a tagged frame enters the transparent port, it
is switched to the double-tagged port
• If the double-tagged port is not a member of the
frame VID, the frame is discarded
• If the double-tagged port is a member of the frame
VID, it removes the tag and transmits the frame
untagged
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)
When operating in the Mode G, the following rules apply:
• No VLANs can be created on the network port.
• Each user port has to be a member of its default VLAN ID, no other VLANs are
valid.
• Both user ports can get the same default VLAN ID.
• In either case, no traffic is allowed between two user ports.
