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.
C-port
When a tagged frame is received on a port,
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,
1.
If a tagged frame with TPID=0x88A8, it is
forwarded.
2.
If the TPID of tagged frame is not 0x88A8
(ex. 0x8810), it will be discarded.
The TPID of frame transmitted by S-
port will be set to 0x88A8
When an untagged frame is received on a port,
a tag (PVID) is attached and then forwarded.
S-custom port
When a tagged frame is received on a port,
1.
If a tagged frame with TPID=0x88A8, it is
forwarded.
2.
If the TPID of tagged frame is not 0x88A8
(ex. 0x8810), it will be discarded.
The TIPID of frame transmitted by S-
custom-port will be set to an self-
customized value, which can be set
by the user using the column of
Ethertype for Custom S-ports.
When an untagged frame is received on a port,
a tag (PVID) is attached and then forwarded.
Ingress Filtering:
If Ingress Filtering is enabled and the ingress port is not a member of a VLAN, the frame from the
ingress port is discarded. By default, ingress filtering is disabled.
Ingress Acceptance:
Select the acceptable ingress traffic type on a port.
Tagged and Untagged:
Both tagged and untagged ingress packets are acceptable on a port.
Tagged Only:
Only tagged ingress packets are acceptable on a port. Untagged packets will be dropped.
Untagged Only:
Only untagged ingress packets are acceptable on a port. Tagged packets will be dropped.
Egress Tagging:
The action taken when packets are sent out from a port.
Untag Port VLAN:
Frames that carry PVID will be removed when leaving from a port. Frames with tags other than
PVID will be transmitted with the carried tags.
Tag All:
Frames are transmitted with a tag.
Untag All:
Frames are transmitted without a tag. This option is only available for ports in Hybrid mode.
Allowed VLAN:
Ports in Trunk and Hybrid mode may control which VLANs they are allowed to become members of.
Access ports can only be member of one VLAN, the Access VLAN. By default, a Trunk or Hybrid port will become
member of all VLANs, and is therefore set to 1-4095.
