4.3.5 VLAN
Management
The VLAN management dialog list the existing VLAN and its configuration.
Introduction to VLAN and VLAN Tag
A VLAN allows a physical network to be divided into several logical networks. A device can belong to
more than one VLAN group. Devices that are not in the same VLAN groups can not talk to each other.
VLAN can provide isolation and security to users and increase performance by limiting broadcast
domain. VLAN tag can be added to the MAC header to identify the VLAN membership of a frame
across bridges. A tagged frame is four bytes longer than an untagged frame. Each port of DAS3 Series
is capable of passing tagged or untagged frames.
Each port has its own Ingress rule. If Ingress rule accept tagged frames only, the switch port will drop
all incoming non-tagged frames. If Ingress rule accept all frame type, the switch port simultaneously
allow the incoming tagged and untagged frames. An untagged frame doesn't carry any VID to which it
belongs. When an untagged frame is received, Ingress Process insert a tag contained the PVID into the
untagged frame. Each physical port has a default VID called PVID (Port VID). PVID is assigned to
untagged frames or priority tagged frames (frames with null (0) VID) received on this port.
