User’s Manual of MGSW-MGSD Series
On egress all frames classified to the Access VLAN are transmitted
untagged. Other (dynamically added VLANs) are transmitted tagged
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:
By default, a trunk port is member of all VLANs (1-4095)
The VLANs that a trunk port is member of may be limited by the use of
Allowed VLANs
Frames classified to a VLAN that the port is not a member of are
discarded
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
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:
Can be configured to be VLAN tag unaware, C-tag aware, S-tag
aware, or S-custom-tag aware
Ingress filtering can be controlled
Ingress acceptance of frames and configuration of egress tagging can
be configured independently
Port VLAN
Determines the port's VLAN ID (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 c
onfiguration is set to untag Port VLAN.
The Port VLAN is called an "A
ccess 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
