Chapter 1 Introduction
Switch Behavior When Handling User and Network Traffic
The way the network and user ports handle the traffic depends on the selected
port mode (transparent, untagged, tagged or double tagged) and frame type
(untagged, tagged or double tagged). Table 1-9 lists all operation modes of the
network and user ports. The modes are explained in greater detail in Table 1-10,
Table 1-11, Table 1-12, Table 1-13, Table 1-14, Table 1-15 and Table 1-16.

is switched to the other transparent port
The transparent port transmits the frame unmodified
(untagged)
Table 1-11. Mode B

Egress
If a tagged frame enters the transparent port, it
is switched to the untagged port
The untagged port removes the tag, and transmits the
frame untagged
If a tagged frame enters the untagged port, it is
switched to the transparent port
The transparent port transmits the frame unmodified
(tagged)
If an untagged frame enters the transparent port,
it is switched to the untagged port
The untagged port transmits the frame unmodified
