Network switches are essential components of modern computer networks.
They connect computers, servers, printers, IP phones, wireless access points and other devices within a Local Area Network (LAN).
Whether you are setting up a small office, managing an enterprise campus or building a data center, selecting the right network switch is important for performance, reliability, security and future growth.
Many companies manufacture Ethernet switches, but their products are designed for different environments.
For example:
- Some switches provide simple plug-and-play connectivity.
- Some support VLANs, security policies and centralized management.
- Some offer advanced Layer 3 routing and redundancy.
- Others are designed for high-speed data centers, cloud infrastructure or industrial networks.
This article explains what network switches do, introduces ten well-known network switch vendors and helps you understand how to choose a suitable platform.
1. What Is a Network Switch and How Does It Work?
A network switch is a device that connects multiple devices within a computer network and forwards Ethernet frames toward their intended destinations.
Most traditional Ethernet switches operate primarily at Layer 2 — the Data Link Layer of the OSI model.
Layer 2 switches use MAC addresses to make forwarding decisions.
How a Network Switch Forwards Traffic
Consider three computers connected to the same switch.
| Device | MAC Address | Switchport |
|---|---|---|
| PC-A | AA:AA:AA:AA:AA:01 | Port 1 |
| PC-B | BB:BB:BB:BB:BB:02 | Port 2 |
| PC-C | CC:CC:CC:CC:CC:03 | Port 3 |
When PC-A sends an Ethernet frame to PC-B:
- The switch receives the frame on Port 1.
- It learns PC-A’s source MAC address.
- It examines the destination MAC address.
- It checks its MAC address table.
- If PC-B’s MAC address is known on Port 2, it forwards the frame through Port 2.
This avoids unnecessarily sending known unicast traffic to every connected device.
What If the Destination MAC Address Is Unknown?
If the switch does not know the destination MAC address, it generally floods the unknown unicast frame through eligible ports in the same VLAN, excluding the receiving port.
Broadcast traffic is also forwarded within the relevant VLAN broadcast domain.
Therefore, it is not accurate to say that a switch always sends traffic to only one port.
Network Switch vs Hub vs Router
| Device | Main Function |
|---|---|
| Hub | Repeats incoming signals to connected ports |
| Layer 2 Switch | Forwards Ethernet frames using MAC addresses |
| Router | Forwards IP packets between networks |
| Layer 3 Switch | Combines Ethernet switching with supported IP routing functions |
Layer 3 switches can provide routing between VLANs and other IP networks.
2. Types of Network Switches — Before Comparing Vendors

Does a More Expensive Switch Always Perform Better?
No.
Performance depends on several factors.
For example:
- Required port speed
- Switching capacity
- Forwarding performance
- Packet buffering
- Network traffic patterns
- Hardware feature support
- Software stability
- Uplink capacity
- Redundancy requirements
A basic switch may be perfectly suitable for a small office but inappropriate as a redundant enterprise core switch.
Likewise, a high-capacity data center switch may provide unnecessary complexity and cost for a network with only ten computers.
Should You Use Multiple Vendors?
Multi-vendor networks are possible and common.
However, administrators should verify interoperability for:
- VLAN tagging
- Spanning Tree
- LACP
- Routing protocols
- Management and monitoring
- Authentication
- Transceiver compatibility
- Vendor-specific stacking or fabric technologies
5. How to Choose the Right Network Switch — Practical Selection Checklist
Choosing a switch should begin with the network requirements, not the brand name.
1. Count the Required Ports
For example, an office has:
- 20 computers
- 4 wireless access points
- 4 IP phones
- 2 printers
Total required connections:
30 ports
A 48-port switch could provide additional capacity for future expansion.
Depending on redundancy and cabling requirements, the organization might instead choose multiple smaller switches.
2. Determine the Access Port Speed
Common choices include:
| Speed | Typical Application |
|---|---|
| 1 Gbps | General office endpoints |
| 2.5 Gbps | Multi-gigabit access points and suitable endpoints |
| 5 Gbps | Higher-capacity edge connectivity |
| 10 Gbps | High-performance workstations, servers and specialized endpoints |
| 25 Gbps and above | Higher-capacity server and aggregation connections |
The endpoint, cable, transceiver and switch must support the required speed.
3. Calculate the PoE Requirements
If a switch must power wireless access points, cameras or phones, verify:
- Number of PoE ports
- Power required by each device
- Per-port PoE capability
- Total switch PoE budget
- Power redundancy requirements
Do not choose a switch based only on its advertised number of PoE ports.
4. Plan Uplink Capacity
An access switch may connect dozens of endpoints through one or more uplinks.
Evaluate:
- Aggregate user traffic
- Application bandwidth
- 10G or higher uplink requirements
- Link aggregation
- Redundant links
- Capacity remaining after failures
5. Verify Security Features
For enterprise access switches, common requirements include:
- IEEE 802.1X
- Port Security
- DHCP Snooping
- Dynamic ARP Inspection
- IP Source Guard
- ACLs
- SSH
- SNMPv3
Support varies by hardware, software and license.
6. Choose the Management Model
Consider whether administrators prefer:
- Local CLI
- Web management
- Centralized on-premises controller
- Cloud management
- API-based automation
Also review licensing, connectivity dependencies and operational requirements.
7. Review Support and Total Cost of Ownership
The switch purchase price is only one part of the total cost.
Additional considerations include:
- Software subscriptions
- Support contracts
- Replacement hardware
- Optics and cables
- Power consumption
- Cooling
- Technical training
- Warranty
- End-of-support timelines

6. Common Mistakes When Comparing Network Switch Vendors
Mistake 1 — Comparing Different Product Categories
A basic unmanaged switch should not be compared directly with a high-capacity data center switch based only on purchase price.
They serve different requirements.
Mistake 2 — Assuming Every Managed Switch Supports Layer 3 Routing
Some managed switches offer only Layer 2 features or limited static routing.
Advanced dynamic routing may require a different hardware model or license.
Mistake 3 — Ignoring the PoE Budget
A switch with 24 PoE-capable ports may not have enough total available power to supply every device at its maximum supported wattage simultaneously.
Mistake 4 — Ignoring Uplink Speeds
A switch with many 1 Gbps access ports and a limited uplink may experience congestion during periods of heavy traffic.
Mistake 5 — Selecting Based on Software Features Alone
A feature available in the operating system may not be hardware-accelerated or supported at the desired scale.
Mistake 6 — Ignoring Support Lifecycle
Older product families may still appear in online documentation or used-equipment listings.
Before purchasing, check the current support status, security update availability and recommended replacement products.
Mistake 7 — Ignoring Security and Management
A switch used in an enterprise environment should provide the visibility and controls required by the organization’s security policy.
