Difference between Industrial Grade Switches and Ethernet Switches
When talking about the differences between industrial switches and ethernet switches, the main aspects involved are:
Design purpose and environmental adaptability
Industrial switches are usually designed to meet the needs of harsh environments, so they have higher environmental adaptability and reliability. Ethernet switches are typically designed for mild office environments.
Enclosure material
Industrial switches typically use sturdy and durable metal materials to resist the effects of environmental factors such as vibration, high temperature, and electromagnetic interference. Ethernet switches typically use plastic enclosures, which are sufficient for light usage.
Protection level
Industrial switches typically have higher protection levels and can work in more severe environments. Ethernet switches typically do not have these protection features.
Temperature range
Industrial switches can operate over a wider temperature range and can withstand higher or lower temperatures. Ethernet switches typically only work within a narrow temperature range.

Understanding Switch Technologies: From Unmanaged to Fully Managed
L2 vs. L3 Switches: Understanding the Difference
Layer 2 (L2) switches operate at the data link layer and forward traffic based on MAC addresses. They are primarily used for switching within the same network, ensuring efficient communication between devices in a LAN. L2 switches do not perform IP-based routing, so traffic between different subnets or VLANs requires an external router.
Layer 3 (L3) switches function at both the data link and network layers, enabling them to process IP addresses in addition to MAC addresses. This allows them to perform routing between VLANs without needing a separate router. L3 switches support features like static and dynamic routing, making them suitable for networks that require inter-subnet communication.
Understanding Network Switches: Unmanaged, Web-Managed, and Fully Managed
Network switches can be categorized into unmanaged, web-managed (smart), and fully managed switches with a console port, each offering different levels of control and functionality.
Unmanaged switches are the most basic type, operating with no configuration options. They are plug-and-play devices that automatically forward traffic between connected devices, making them ideal for small networks or simple setups where manual control over traffic is unnecessary. While easy to use, they lack features like VLANs, Quality of Service (QoS), and monitoring capabilities.
Web-managed (smart) switches provide a middle ground between unmanaged and fully managed switches. They feature a simplified web-based interface for configuring essential network settings such as VLANs, QoS, and traffic monitoring. These switches offer more control than unmanaged ones while remaining accessible to users who may not have extensive networking expertise. However, they lack the deep customization and automation capabilities of fully managed switches.
Fully managed switches with a console port provide the highest level of network control and flexibility. They support advanced features such as dynamic routing, access control lists (ACLs), SNMP monitoring, and remote configuration through CLI-based protocols like SSH and Telnet. The inclusion of a console port allows direct access via a serial connection, enabling administrators to configure and troubleshoot the switch even if network connectivity is lost. This makes them essential in enterprise environments where high availability, security, and detailed network management are critical.
At NovusDash’s networking solutions we offer different categories of switching from unmanaged, web managed and fully managed switches. Please check out our products families below to explore more.
LAN Campus Solution Design
A hierarchical network design involves dividing the network into discrete layers. Each layer, or tier, in the hierarchy provides specific functions that define its role within the overall network. This helps the network designer and architect to optimize and select the right network hardware, software, and features to perform specific roles for that network layer. Hierarchical models apply to both LAN and WAN design.
The benefit of dividing a flat network into smaller, more manageable blocks is that local traffic remains local. Only traffic that is destined for other networks is moved to a higher layer
A typical enterprise hierarchical LAN campus network design includes the following three layers:
- Access layer: Provides workgroup/user access to the network
- Distribution layer: Provides policy-based connectivity and controls the boundary between the access and core layers
- Core layer: Provides fast transport between distribution switches within the enterprise campus
There are no absolute rules for the way a campus network is physically built. While it is true that many campus networks are constructed using three physical tiers of switches, this is not a strict requirement. In a smaller campus, the network might have two tiers of switches in which the core and distribution elements are combined in one physical switch. This is referred to as a collapsed core design.
1. Access Layer
In a LAN environment, the access layer highlighted grants end devices access to the network. In the WAN environment, it may provide teleworkers or remote sites access to the corporate network across WAN connections.
The access layer for a small business network generally incorporates Layer 2 switches and access points providing connectivity between workstations and servers.
The access layer serves a number of functions, including
- Layer 2 switching
- High availability
- Port security
- QoS classification and marking and trust boundaries
- Address Resolution Protocol (ARP) inspection
- Virtual access control lists (VACLs)
- Spanning tree
- Power over Ethernet (PoE) and auxiliary VLANs for VoIP
2. Distribution Layer
The distribution layer aggregates the data received from the access layer switches before it is transmitted to the core layer for routing to its final destination. The distribution layer is the boundary between the Layer 2 domains and the Layer 3 routed network.
The distribution layer device is the focal point in the wiring closets. Either a router or a multilayer switch is used to segment workgroups and isolate network problems in a campus environment.
A distribution layer switch may provide upstream services for many access layer switches.
The distribution layer can provide
- Aggregation of LAN or WAN links.
- Policy-based security in the form of access control lists (ACLs) and filtering.
- Routing services between LANs and VLANs and between routing domains (RIP, OSPF).
- Redundancy and load balancing.
- A boundary for route aggregation and summarization configured on interfaces toward the core layer.
- Broadcast domain control, because routers or multilayer switches do not forward broadcasts. The device acts as the demarcation point between broadcast domains.
3. Core Layer
The core layer is also referred to as the network backbone. The core layer consists of high-speed network devices such as L3 managed switches with 10G interfaces. These are designed to switch packets as fast as possible and interconnect multiple campus components, such as distribution modules, service modules, the data center, and the WAN edge.
The core layer is critical for interconnectivity between distribution layer devices (for example, interconnecting the distribution block to the WAN and Internet edge).
The core should be highly available and redundant. The core aggregates the traffic from all the distribution layer devices, so it must be capable of forwarding large amounts of data quickly.
Considerations at the core layer include
- Providing high-speed switching (i.e., fast transport)
- Providing reliability and fault tolerance
- Scaling by using faster, and not more, equipment
- Avoiding CPU-intensive packet manipulation caused by security, inspection, quality of service (QoS) classification, or other processes
