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.
■ Untagged Only
