4.By default, all frames but frames classified to the Port VLAN (a.k.a.
Native VLAN) get tagged on egress. Frames classified to the Port VLAN do
not get C-tagged on egress.
5.Egress tagging can be changed to tag all frames, in which case only
tagged frames are accepted on ingress.
Hybrid:
Hybrid ports resemble trunk ports in many ways but adds additional port
configuration features. In addition to the characteristics described for
trunk ports, hybrid ports have these abilities:
1. Can be configured to be VLAN tag unaware or, C-tag aware, S-tag aware,
or S-custom-tag aware.
2.Ingress filtering can be controlled.
3.Ingress acceptance of frames and configuration of egress tagging can be
configured independently.
Determines the port's VLAN ID (a.k.a. PVID). Allowed VLANs are in the
range through , default being 1. On ingress, frames get classified to
1 4095
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.
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
