Unaware
The function of
Unaware can be
used for
802.1QinQ
(double tag).
When the port receives untagged frames,
an untagged frame obtains a tag (based
on PVID) and is forwarded.
When the port receives tagged frames:
1. If the tagged frame contains a TPID of
0x8100, it will become a double-tag frame
and will be forwarded.
2. If the TPID of tagged frame is not
0x8100 (ex. 0x88A8), it will be discarded.
The TPID of a frame
transmitted by
Unaware port will be
set to 0x8100.
The final status of the
frame after egressing
will also be affected
by the Egress Rule.
C-port
When the port receives untagged frames,
an untagged frame obtains a tag (based
on PVID) and is forwarded.
When the port receives tagged frames:
1. If the tagged frame contains a TPID of
0x8100, it will be forwarded.
2. If the TPID of tagged frame is not
0x8100 (ex. 0x88A8), it will be discarded.
The TPID of a frame
transmitted by C-port
will be set to 0x8100.
S-port
When the port receives untagged frames,
an untagged frame obtains a tag (based

2. If the TPID of tagged frame is not
0x88A8 (ex. 0x8100), it will be discarded.
The TPID of a frame
transmitted by S-port
will be set to 0x88A8.
S-custom-port
When the port receives untagged frames,
an untagged frame obtains a tag (based
on PVID) and is forwarded.
When the port receives tagged frames:

0x8100, it will be forwarded.
2. If the TPID of tagged frame is not
0x88A8 (ex. 0x8100), it will be discarded.
The TPID of a frame
transmitted by S-
custom-port will be
set to a self-
customized value,
which can be set by
the user via
