.
Member of exactly one VLAN, the Port VLAN (a.k.a. Access VLAN),
which
by default is 1
2.Accepts untagged and C-tagged frames
3.Discards all frames that are not classified to the Access VLAN
4.On egress all frames are transmitted untagged
Trunk:
Trunk ports can carry traffic on multiple VLANs simultaneously, and are
normally used to connect to other switches. Trunk ports have the
following characteristics:
1. By default, a trunk port is member of all VLANs (1-4095)
2.The VLANs that a trunk port is member of may be limited by the use of
Allowed VLANs
3.Frames classified to a VLAN that the port is not a member of are
discarded
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, 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
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
