Description of VLAN (Virtual LAN)
㧔
1
㧕
VLAN configuration (Group)
Equipped with the Layer-2 switch function, the Equipment allows each port (VDSL and 10/100BASE
ports) to be independently used. (Switching HUB function)
Virtually grouping each port, the VLAN is capable of handling each independent port as identical
groups.
Communication is allowed between the identical groups, but not between the different ones.
As the initial VLAN (base VLAN), for example, each port belongs to the same group as the upstream
side (network side: 10/100BASE Port 3 and 10/100BASE Port 4) as an independent group. In this
case, data communication is allowed from each VDSL port to the 10/100BASE Ports 3 and 4, but
not allowed between each VDSL port. Placing them in the same group requires you to pay heed to
privacy security, because the communication data in the group is made visible.

VLAN ID
A number to identify the set VLAN group. It is used for connecting multiple equipments to configure
a VLAN group among them. It is necessary to set the VLAN ID, even if multiple equipments are not
used.

PVID
ID of the port VLAN. It allocates the set VLAN groups to respective ports. Select the VLAN ID used
(belonging) per port.

Cascade connection
Multiple units of this equipment may be connected. When cascading to another equipment, use the
10/100BASE Ports 1 and 2, because they are MDI-X.
As the initial VLAN, the 10/100BASE Ports 1 and 2 assume only the 10/100BASE Ports 3 and 4
as an identical group. In this case, the data from the 10/100BASE Ports 3 (another one of
connected multiple equipments) flows only to the 10/100BASE Ports 3 and 4. The data does not
flow to each VDSL port. In case of the initial VLAN, therefore, the 10/100BASE Ports 1 and 2 are
valid only when connecting multiple equipments.

Tag output setting
In VLAN group setting, this is to add a VLAN identification tag (information) to the data output from
each port. Generally, select Untag (does not add the tag); select this when configuring the VLAN at
each port among multiple equipments by cascade connection, etc.
