tag, if a tag is required.
Unaware:
On ingress, all frames, whether carrying a VLAN tag or not, get
classified to the Port VLAN, and possible tags are not removed
on egress.
C-Port:
On ingress, frames with a VLAN tag with TPID = 0x8100 get
classified to the VLAN ID embedded in the tag.
If a frame is untagged or priority tagged, the frame gets
classified to the Port VLAN.
If frames must be tagged on egress, they will be tagged with a
C-tag.
S-Port:
On ingress, frames with a VLAN tag with TPID = 0x88A8 get
classified to the VLAN ID embedded in the tag.
Priority-tagged frames are classified to the Port VLAN.
If the port is configured to accept Tagged Only frames
(see Ingress Acceptance below), frames without this TPID are
dropped.
If frames must be tagged on egress, they will be tagged with
an S-tag.
S-Custom-Port:
On ingress, frames with a VLAN tag with a TPID equal to
the Ethertype configured for Custom-S ports get classified to
the VLAN ID embedded in the tag.
Priority-tagged frames are classified to the Port VLAN.
If the port is configured to accept Tagged Only frames
(see Ingress Acceptance below), frames without this TPID are
dropped.
If frames must be tagged on egress, they will be tagged with
the custom S-tag.
Ingress Filtering
Hybrid ports allow for changing ingress filtering. Access and
Trunk ports always have ingress filtering enabled.
If ingress filtering is enabled (checkbox is checked), frames
classified to a VLAN that the port is not a member of get
discarded.
If ingress filtering is disabled, frames classified to a VLAN that
