Configure a network

Description

The Vision Connector requires a special network configuration for communication with cameras via an Ethernet interface. This network configuration is called Layer 2 Access. It is a prerequisite for the installation and operation of the Vision Connector.

A physical Ethernet network interface (gray box in the figure) is used for multiple (logical) network interfaces. This port is shared by real and virtual interfaces, each of which has its own IP and MAC address.

The 'eno3' interface of the Docker container is visible to the outside as its own network interface in the network with its IP address and also its own MAC address.

Preparation

You must configure the following:

• Assign an IP address to the Ethernet interface of the LINUX host (eno3).

• Specify an IP address range used by Docker for the Layer 2 network.

  This address range applies to the macvlan bridge and to Docker containers connected to the Layer 2 Docker network.

Follow these recommendations for Layer 2 configuration:

• The IP addresses of the networks shown in blue and green in the figure above (eth1) must belong to the same IP subnet.

• For the IP address shown in yellow in the figure above, it is recommended that you also configure the same IP subnet. Technically, it may belong to a different IP subnet.

• All IP addresses must be unique. Duplicate use of the same IP address is not allowed.

• Ensure that all connected cameras are configured with a unique IP address that does not exist in the Layer 2 network.

• You cannot use DHCP for the Layer 2 interface because Docker does not fully support DHCP.

Procedure

To configure the Layer 2 network, follow these steps:

1. In the user interface of the IED, select "Settings > Connectivity > LAN Network".

   

2. Open the network interface for editing.

   

3. Enter the "Start IP Address", the "Netmask" and the "IP Address Range".

   

4. Optional: Select "Advanced Settings" and specify the IP address of the gateway.
