
Port VLAN :
Determines the port's VLAN ID (a.k.a. PVID). Allowed VLANs are in the range 1 through
4095,
default being 1.
On ingress, frames get classified to the Port VLAN if the port is configured as VLAN
unaware, the frame is untagged, or VLAN awareness is enabled on the port, but the frame
is
priority tagged (VLAN ID = 0).
On egress, frames classified to the Port VLAN do not get tagged if Egress Tagging
configuration is set to untag Port VLAN.
The Port VLAN is called an "Access VLAN" for ports in Access mode and Native VLAN for
ports in Trunk or Hybrid mode.

Port Type :
Ports in hybrid mode allow for changing the port type, that is, whether a frame's VLAN tag
is used to classify the frame on ingress to a particular VLAN, and if so, which TPID it reacts
on. Likewise, on egress, the Port Type determines the TPID of the 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 = 0x8100 or 0x88A8 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 an S-tag.
S-Custom-Port:
On ingress, frames with a VLAN tag with a TPID = 0x8100 or equal to the
Ethertype configured for Custom-S ports 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 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 the port is not a member of
are accepted and forwarded to the switch engine. However, the port will never transmit
frames classified to VLANs that it is not a member of.

Ingress Acceptance :
Hybrid ports allow for changing the type of frames that are accepted on ingress.
Tagged and untagged
both tagged and untagged frames are accepted.
Tagged Only
Only tagged frames are accepted on ingress. Untagged frames are discarded.
