The following settings affect only the LAN ports.

VLAN
Order No. 006-130-101/102
VLANs allow to segment a network and to operate this as a plurality of small networks.
Therefore tagged VLANs as well as port-based VLANs are available.
VLANs can be set up in the web interface at
Configuration > VLAN
.
In the left table the existing VLAN groups are listed (for more details take a look at section 7.3.1.1).
The table contains the ID and the name of a button with which the group can be removed. With "add
VLAN group", a window opens where you can create additional groups. For this you only have to enter
the ID and name and you have to actuate the button "add VLAN". Alternatively, you can close the
window with the close button or the X.
The right table shows the settings of the respective interfaces
. By pressing the “Edit” button a window
opens with the interface to be configured.
The interfaces 1 to 9 and the connection to the CPU are available. The interfaces which are displayed
as a single interface with the name of the trunk group are in a Trunk Group. They can only be
configured together.
7.1.1. Tagged VLANs
Tagged VLANs enable complex VLAN configurations. The Ethernet frames can be extended to
include an 802.1Q header containing a VLAN ID among others. The VLAN-ID is in the range of 1-4095
and assigns the Ethernet frame to a VLAN. A switch port will accept only Ethernet frames whose
VLAN ID corresponding to the configured VLAN IDs. The frames can be delivered only to ports that
are in the "tag-based" mode and are also a member of the VLAN.
You can assign any several, but at least one tag to an interface. The interface receives a primary tag,
which can be used to tag untagged packets.
