10.3.4 VLAN
VLANs allow to segment a network and operate this like several small networks.
VLANs can be configured in the web interface under
Configuration > VLAN
.
The configuration options are very flexible; connections between all ports and in
each direction can be permitted or prohibited.
This is specified in the table as follows: Packets that arrive at one of the ports at the
left are only forwarded to ports which are checked in this line.
In most cases, the switching options for incoming and outgoing traffic are symmet-
rical. To activate symmetric features, check "symmetric" below the table.
To apply all settings, click on "submit all".

In order to accelerate the setting effort, "check all" or "clear all" can be
used to select all or no interfaces. The transfer of the settings to the
switch must always be made in addition.
The following image shows the configuration of two VLAN networks consisting of
ports 1, 2, 3 or 4, 5. Port 6 exists in both networks.
Therefore, ports 1, 2, 3 cannot communicate with the ports 4, 5. Port 6 can com-
municate with each of the other ports.
