Configure static network interface

This guide explains how to configure static network interfaces on Industrial Edge Devices.

Industrial Edge Devices support multiple network interfaces that can be configured with static IP addresses. Understanding the difference between gateway and non-gateway interfaces is crucial for proper network configuration.

Gateway interface configuration

The gateway interface is the primary network interface used for routing traffic to external networks and connecting to the Industrial Edge Management (IEM).

Gateway IP requirement

When configuring a static IP address on the gateway interface, the IP address of the gateway of this network is always required. This is necessary to prevent inconsistent system states.

Workaround for non-gateway scenarios

For Static IP configuration on a network interface where there is no gateway configure in the network/subnet, it is recommended to use an arbitrary value like 0.0.0.0 as the Gateway IP address.

This allows you to save the configuration while technically meeting the system requirement.

NOTICE

Configuring a static IP on the gateway interface without specifying a gateway IP can lead to network connectivity issues and an unstable system state.

Non-gateway interface configuration

For additional network interfaces that are not used for external routing (such as connecting cameras, sensors, or other local network devices), you can configure static IP addresses without requiring a gateway IP.

Procedure

  1. Select the gateway interface: First, ensure that another interface is designated as the gateway interface in your network configuration.

  2. Configure the non-gateway interface: Once a different interface is set as the gateway, you can configure additional interfaces with static IP settings without entering a gateway IP address.

Common use cases

Local network connectivity

Non-gateway interfaces are typically used for:

  • Connecting industrial cameras
  • Establishing communication with PLCs or other controllers
  • Creating isolated local networks for specific applications
  • Connecting to devices that don't require internet access

In these scenarios, configuring the interface with a static IP address and subnet mask (without a gateway) is the recommended approach.

Example configuration

Gateway Interface (eth0):

  • IP Address: 192.168.1.100
  • Subnet Mask: 255.255.255.0
  • Gateway: 192.168.1.1 (required)

Non-Gateway Interface (eth1) for local camera network:

  • IP Address: 10.0.0.1
  • Subnet Mask: 255.255.255.0
  • Gateway: (leave empty - not required)

Best practices

  • Always designate one interface as the gateway interface for IEM connectivity
  • Use non-gateway interfaces for local, isolated networks
  • Plan your IP address scheme to avoid conflicts between different network segments
  • Document which interface serves which purpose in your deployment
