FAQs about Layer 2 switches

An industrial Layer 2 switch connects devices within an Ethernet network and controls how traffic is forwarded between them. In industrial environments, these switches are built to support reliable communication under demanding conditions, with features such as VLANs, QoS, multicast management and redundancy to improve traffic control, security and availability.

Use a managed industrial Layer 2 switch when the network needs more control, visibility and resilience than an unmanaged switch can provide. This is typically important when you need to segment traffic, prioritise critical communication, monitor network performance or reduce the risk of downtime in operational environments.

Layer 2 switches manage traffic within the same network, while Layer 3 switches can also route traffic between different VLANs, subnets or network segments. In practice, Layer 2 switches are often used to build secure and resilient local industrial networks, while Layer 3 switches are selected when routing between larger or distributed networks is required.

VLANs allow a Layer 2 network to be divided into separate logical segments without requiring separate physical infrastructure. In industrial networks, this makes it easier to separate traffic from different devices, systems or applications, helping improve security, reduce unnecessary traffic and protect critical communications.

Quality of Service, or QoS, helps prioritise important traffic in a Layer 2 network. For industrial applications, this can help ensure that time-critical communication is handled before less critical data, supporting more predictable network performance during periods of high traffic.

Redundancy helps maintain communication if a network link or device becomes unavailable. In Layer 2 industrial networks, redundancy mechanisms can redirect traffic through alternative paths, reducing downtime and helping maintain availability for systems where stable communication is essential.

How to choose an industrial Layer 2 managed switch


When selecting an Layer 2 managed industrial switch, consider network size, port requirements, traffic prioritisation, redundancy needs and environmental conditions. Industrial applications often demand robust cybersecurity, reliable operation in harsh environments and support for long-term network management.

Use the filters above to compare Westermo Layer 2 managed switches by connectivity, speed, input voltage, mounting options, approvals and supported standards.
