Configure virtual local area network (VLAN)

From image version 140501, a virtual local area network (VLAN) can be configured on the Ethernet interface (X001). The VLAN forms a logical network segment and its own broadcast domain. This means that the network is subdivided regardless of the physical network topology on-site. The data traffic of a VLAN's associated devices is isolated from other VLANs.

The configuration takes place in the file /etc/boot.conf on the microSD card. Update the image first if you are using an older image version on the embedded PC (see: Update image).

Requirements:

card reader for microSD cards

Proceed as follows:

1. Switch the embedded PC off and take the microSD card out of the embedded PC.

2. Insert the microSD card into an external card reader and open the microSD card's folder tree.

3. Open the boot.conf file under \etc and navigate to the entries for the VLAN.

; VLanEnabled on Interface 0 can be true or false (default). If true, VLAN Tagging is supported.
0:VLanEnabled = false
; VLanID on Interface 0 can be set from 0 to 4094. When VLAN is enabled, it defines the operating VLAN.
0:VLanID = 1
; VLanPriority on Interface 0 can be set from 0 to 7. When VLAN is enabled, it defines the priority of the packets, sent with a VLAN Tag. 0 has a higher priority than 7.
0:VLanPriority = 0

4. Edit the parameters VLanEnabled, VLanID und VLanPriority according to your requirements.

Save the changes and reinstall the microSD card in the embedded PC. The settings will take effect after the device is started.
