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:
If the tagged frame contains a TPID of
0x8100, it will be forwarded.
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
Ethertype for Custom S-
ports.
