Egress Action
Unaware
When a tagged frame is received on a port,
1.
If the tagged frame with TPID=0x8100, it
becomes a double-tag frame and is
forwarded.
2.
If the TPID of tagged frame is not 0x8100
(ex. 0x88A8), it will be discarded.
The TPID of frame transmitted by
Unaware port will be set to 0x8100.
The final status of the frame after
egressing are also affected by egress
rule.
When an untagged frame is received on a port,
a tag (PVID) is attached and then forwarded.

1.
If a tagged frame with TIPID=0x8100, it is
forwarded.
2.
If the TPID of tagged frame is not 0x8100
(ex. 0x88A8), it will be discarded.
The TPID of frame transmitted by C-
port will be set to 0x8100.
When an untagged frame is received on a port,
a tag (PVID) is attached and then forwarded.
S-port
When a tagged frame is received on a port,
