24 Gigabit Ethernet Ports for Business Networks
The TL-SG3428 provides 24 auto-negotiating 10/100/1000Mbps RJ45 ports, giving businesses enough wired connectivity for a substantial number of network devices from a single 1U switch.
Compatible devices can include:
- Desktop PCs
- Business workstations
- Servers
- NAS storage systems
- Printers
- Wireless access points with separate power
- IP cameras with separate power
- VoIP phones with separate power
- Network controllers
- Routers and gateways
- Additional managed or unmanaged switches
Auto-Negotiation and Auto MDI/MDIX
The copper Ethernet ports support Auto-Negotiation and Auto MDI/MDIX, allowing the switch to automatically determine compatible connection speeds and cable orientation with supported Ethernet devices.
Four Gigabit SFP Fibre Uplink Slots
In addition to its 24 copper ports, the TL-SG3428 provides four SFP slots supporting 100Mbps or 1000Mbps compatible fibre modules.
These slots allow network administrators to use fibre or other compatible SFP media for:
- Switch-to-switch uplinks
- Connections between network cabinets
- Long-distance fibre links
- Connections between different floors
- Building-to-building links
- Fibre network infrastructure
- Network redundancy
Why Use SFP Fibre Instead of Copper Ethernet?
Fibre can provide several practical advantages in suitable network installations, particularly when links need to extend beyond conventional copper Ethernet distances.
Depending on the chosen SFP transceiver and fibre type, fibre connectivity can offer:
- Longer cable runs
- Electrical isolation between network equipment
- Resistance to electromagnetic interference
- Reliable connections between network cabinets
- Single-mode or multimode deployment options
Important: These Are Gigabit SFP Slots, Not 10G SFP+
The four optical uplink interfaces on the TL-SG3428 are Gigabit SFP slots. They do not provide 10Gbps SFP+ connectivity.
The current SG3428 specification lists these interfaces as:
- 4 × 100/1000Mbps SFP slots
If your network requires 10Gbps fibre or DAC uplinks, the TP-Link TL-SG3428X / SG3428X is the faster model with four 10Gbps SFP+ interfaces.
TL-SG3428 vs TL-SG3428X
The TL-SG3428 and TL-SG3428X have very similar names but substantially different uplink capabilities.
- TL-SG3428: 24 × Gigabit RJ45 + 4 × Gigabit SFP
- TL-SG3428X: 24 × Gigabit RJ45 + 4 × 10Gbps SFP+
The standard TL-SG3428 is therefore suitable where Gigabit fibre uplinks are sufficient, while the X version is more appropriate where 10Gbps backbone connectivity is required.
56Gbps Switching Capacity
The TL-SG3428 provides a manufacturer-rated 56Gbps switching capacity.
This corresponds to the bandwidth required to handle the switch's 28 Gigabit interfaces at full duplex, helping the switch process simultaneous network traffic efficiently.
41.66Mpps Packet Forwarding Rate
TP-Link specifies a forwarding rate of approximately 41.66 million packets per second.
This level of packet-processing capability makes the switch suitable for multi-device professional networks where many endpoints may generate traffic simultaneously.
16K MAC Address Table
TP-Link's current SG3428 V2.30 specification provides a 16,000-entry MAC address table.
A larger MAC table gives the switch capacity to learn and track a substantial number of network-device addresses, which can be useful in large or segmented business environments.
12Mbit Packet Buffer
The current SG3428 hardware specification lists a 12Mbit packet buffer.
Packet buffering helps temporarily hold data when network traffic arrives faster than a destination interface can immediately forward it, helping the switch manage short traffic bursts more effectively.
9KB Jumbo Frames
The TL-SG3428 supports Jumbo Frames up to 9KB.
Jumbo Frames can reduce protocol overhead for certain high-volume network transfers, including suitable server, backup and NAS workloads.
All relevant devices in the communication path must use compatible MTU settings for Jumbo Frames to operate correctly.
TP-Link Omada SDN Centralised Management
The TL-SG3428 integrates with TP-Link Omada Software Defined Networking, allowing compatible switches, wireless access points and gateways to be administered through a centralised management platform.
This can reduce administrative workload when an organisation manages multiple network devices or multiple sites.
Compatible Omada Management Options
TP-Link lists centralised management support through compatible:
- Omada Hardware Controllers
- Omada OC200
- Omada OC300
- Omada Software Controller
- Omada Cloud-Based Controller
Unified Wired and Wireless Network Management
An Omada deployment can bring compatible:
- Managed switches
- Wireless access points
- Routers
- Gateways
into one management environment, making it easier to monitor and administer a complete wired and wireless network.
Omada App Support
The switch supports management through the TP-Link Omada mobile app when connected to a compatible Omada Controller deployment.
This allows authorised administrators to monitor compatible networks remotely without needing to connect directly to the switch's local web interface.
Important Controller Requirement
An Omada Controller is not required for standalone operation.
However, Omada App access and centralised cloud management require a compatible:
- Omada Hardware Controller
- Omada Software Controller
- Omada Cloud-Based Controller
Zero-Touch Provisioning
The SG3428 supports Zero-Touch Provisioning when deployed with TP-Link's compatible Omada Cloud-Based Controller.
This can be valuable for businesses deploying network equipment to remote sites because switches can be prepared and administered centrally rather than requiring every configuration task to be performed locally.
Standalone Managed Switch Operation
The TL-SG3428 does not have to be used with Omada.
It also provides comprehensive standalone administration through:
- Web-based graphical interface
- Command Line Interface
- RJ45 console connection
- Micro-USB console connection on applicable revisions
- Telnet
- SSH
- SNMP v1/v2c/v3
- RMON
This makes it suitable for conventional managed networks as well as complete Omada SDN deployments.
L2+ Managed Switching
The TL-SG3428 is an L2+ managed switch, meaning it combines extensive Layer 2 switching features with selected Layer 3 capabilities.
This provides substantially more control than an unmanaged Ethernet switch while allowing features such as static routing to be performed directly by the switch.
Static IPv4 and IPv6 Routing
The SG3428 supports static IPv4 and IPv6 routing, allowing administrators to create predefined routes between compatible network interfaces and subnets.
TP-Link's current SG3428 specification supports up to 48 IPv4/IPv6 static routes.
Reduce Unnecessary Router Traffic
In a correctly configured business network, static routing can allow certain internal traffic to move between local networks without sending every packet to an upstream router.
This can be useful when a network is separated into different VLANs for:
- Employees
- Servers
- Voice systems
- Management devices
- Guests
- Surveillance equipment
Current SG3428 IP Interface Support
TP-Link's current SG3428 V2.30 specification lists up to 128 IPv4/IPv6 interfaces. Earlier TL-SG3428 hardware revisions may provide a lower interface limit, so organisations where this particular capacity is critical should check the hardware revision printed on the physical switch.
DHCP Server and DHCP Relay
The SG3428 supports advanced DHCP functionality including:
- DHCP Server
- DHCP Interface Relay
- DHCP VLAN Relay
- DHCP Layer 2 Relay
These functions can help administrators manage IP-address assignment across segmented network environments.
802.1Q VLAN Network Segmentation
The switch supports IEEE 802.1Q VLANs with up to 4K VLAN groups.
VLANs allow multiple logically separate networks to operate over the same physical switching infrastructure.
Typical VLAN Uses
A business may create separate VLANs for:
- Staff computers
- Guest Wi-Fi
- Servers
- VoIP equipment
- CCTV cameras
- Management interfaces
- IoT devices
This can improve network organisation, security and traffic control when correctly configured.
Advanced VLAN Features
The SG3428 supports a broad range of VLAN technologies including:
- 802.1Q Tagged VLAN
- MAC VLAN
- Protocol VLAN
- Private VLAN
- Voice VLAN
- GVRP
- Port-Based QinQ
- Selective QinQ
Link Aggregation and LACP
The TL-SG3428 supports both static Link Aggregation and IEEE 802.3ad LACP.
Multiple compatible network interfaces can be grouped into a logical link where the connected equipment supports matching aggregation.
Why Use LACP?
Potential benefits include:
- Higher aggregate bandwidth between compatible devices
- Redundant network links
- More resilient server connections
- Aggregated switch-to-switch uplinks
- NAS link aggregation
Link Aggregation generally increases total bandwidth across multiple network flows rather than making one individual network transfer exceed the speed of a single member link.
Spanning Tree Protocol Support
The switch supports:
- IEEE 802.1D STP
- IEEE 802.1W RSTP
- IEEE 802.1S MSTP
Spanning Tree protocols help prevent Ethernet loops when redundant paths exist between network switches.
Additional STP Protection
TP-Link also provides STP security functions including:
- TC Protect
- BPDU Filter
- Root Protect
Loopback Detection
The SG3428 supports both port-based and VLAN-based loopback detection.
This can help administrators identify network loops that could otherwise generate broadcast storms and disrupt Ethernet connectivity.
ERPS Ethernet Ring Protection
Current SG3428 hardware and firmware support ERPS – Ethernet Ring Protection Switching.
ERPS is designed for networks built using ring topologies, providing rapid recovery if an Ethernet link in the ring fails.
This feature can be particularly useful in enterprise, campus and ISP-style network designs where connection resilience is important.
IGMP Snooping for Multicast Networks
The switch supports IGMP Snooping to intelligently manage IPv4 multicast traffic.
Instead of unnecessarily forwarding every multicast stream to every switch port, IGMP Snooping allows the switch to identify which interfaces actually need particular multicast traffic.
Useful for IPTV and Multicast Video
Multicast management can be valuable for:
- IPTV
- Enterprise video distribution
- Multicast streaming
- Network video applications
MLD Snooping for IPv6
For IPv6 networks, the SG3428 also supports MLD Snooping, providing similar multicast-management functionality for IPv6 traffic.
Multicast VLAN Registration
MVR – Multicast VLAN Registration allows multicast traffic to be distributed across appropriate VLAN configurations without unnecessarily duplicating multicast streams.
Advanced Quality of Service
The TL-SG3428 provides L2/L3/L4 Quality of Service functionality with eight priority queues.
Supported traffic prioritisation includes:
- 802.1p CoS
- DSCP priority
- Strict Priority scheduling
- Weighted Round Robin
- Combined SP + WRR scheduling
Prioritise Voice and Video
QoS can help prioritise delay-sensitive network applications such as:
- VoIP calls
- Video conferencing
- Real-time communications
- Business-critical applications
This is useful when important real-time traffic shares network bandwidth with downloads, backups or other high-volume transfers.
Bandwidth Control
The switch supports port-based and flow-based rate limiting.
Administrators can use bandwidth controls to limit how much network capacity particular devices or traffic classes can consume.
Access Control Lists
Comprehensive Access Control Lists allow network administrators to permit, restrict or redirect traffic according to defined rules.
ACL rules can use information including:
- Source MAC address
- Destination MAC address
- VLAN ID
- Source IP address
- Destination IP address
- IP protocol
- TCP/UDP ports
- DSCP
- IPv6 information
802.1X Network Authentication
The TL-SG3428 supports IEEE 802.1X authentication, allowing compatible network infrastructure to require authentication before access is granted.
Supported authentication functionality includes:
- Port-based authentication
- MAC-based authentication
- MAB – MAC Authentication Bypass
- Guest VLAN
- VLAN assignment
- RADIUS authentication
- RADIUS accounting
- TACACS+
IP-MAC-Port Binding
IP-MAC-Port Binding allows administrators to associate IP addresses, MAC addresses and switch ports as part of a controlled network-access strategy.
TP-Link's current specification supports up to 512 IPv4 binding entries and additional IPv6-MAC-Port binding functionality.
DHCP Snooping
DHCP Snooping can help protect a managed network from unauthorised or rogue DHCP servers by controlling which switch interfaces are trusted to provide DHCP information.
ARP Inspection
ARP Inspection can help protect networks against certain ARP spoofing techniques by validating ARP traffic against trusted network information.
IPv4 and IPv6 Source Guard
The current SG3428 platform supports both IPv4 and IPv6 Source Guard, providing additional control over which source addresses are permitted on selected interfaces.
Port Security
The switch provides static and dynamic Port Security and can restrict the number of MAC addresses allowed through particular interfaces.
Current SG3428 specifications support up to 64 secure MAC addresses per port.
Storm Control
Broadcast, multicast and unknown-unicast Storm Control can help prevent abnormal traffic from consuming excessive switching capacity.
TP-Link provides kbps, ratio and packets-per-second control methods on supported configurations.
DoS Defence
The TL-SG3428 includes protection against a range of common Denial-of-Service attack patterns, helping administrators protect network availability against certain malformed or malicious traffic.
Port Isolation
Port Isolation allows selected Ethernet ports to be prevented from communicating directly with one another while retaining access to designated upstream interfaces.
This can be useful in:
- Hotels
- Student accommodation
- Guest networks
- Shared business networks
Port Mirroring for Diagnostics
The switch supports Port Mirroring, allowing network traffic from selected interfaces to be copied to a monitoring port.
This is useful for:
- Packet capture
- Network diagnostics
- Security monitoring
- Performance troubleshooting
sFlow Network Traffic Monitoring
Current SG3428 hardware and firmware provide sFlow functionality for compatible network-monitoring environments.
sFlow can provide traffic visibility and statistics to suitable monitoring platforms without requiring full packet capture of every network flow.
Ethernet OAM
The SG3428 includes IEEE 802.3ah Ethernet Operations, Administration and Maintenance functionality on current hardware/firmware.
OAM features can help service providers and network administrators monitor and troubleshoot Ethernet links.
DDM – Digital Diagnostic Monitoring
Digital Diagnostic Monitoring can provide diagnostic information from compatible SFP optical transceivers.
Available information depends on the installed module but may include operational parameters useful for monitoring optical links.
IPv4 and IPv6 Dual-Stack Networking
The TL-SG3428 supports both IPv4 and IPv6, allowing it to operate in modern dual-stack networks.
IPv6 functions include:
- IPv4/IPv6 dual stack
- IPv6 interfaces
- Static IPv6 routing
- IPv6 ACL
- MLD Snooping
- IPv6 Neighbor Discovery
- PMTU Discovery
- ICMPv6
- TCPv6 / UDPv6
- DHCPv6 Client
- IPv6 SNMP
- IPv6 SSH
- IPv6 HTTPS
SNMP and RMON Management
The switch supports:
- SNMP v1
- SNMP v2c
- SNMP v3
- SNMP Trap / Inform
- RMON groups 1, 2, 3 and 9
This enables integration with compatible third-party network-management and monitoring platforms.
Dual Image and Dual Configuration
The SG3428 supports Dual Image and Dual Configuration.
Maintaining alternate firmware and configuration information can provide additional resilience during administrative changes or firmware maintenance.
Built-In Cable Diagnostics
Integrated cable diagnostics can help network administrators identify certain physical Ethernet cable faults directly from the switch's management interface.
This can simplify troubleshooting where a wired network connection unexpectedly stops working.
Fanless Design for Silent Operation
The TL-SG3428 uses passive fanless cooling.
Because there is no internal cooling fan, the switch produces no fan noise and eliminates a mechanical component that could otherwise require maintenance over time.
Suitable for Noise-Sensitive Installations
Fanless operation is particularly useful in:
- Offices
- Meeting rooms
- Classrooms
- Retail shops
- Home offices
- Reception areas
- Quiet network cupboards
Low-Power Non-PoE Design
The SG3428 does not include PoE power circuitry, helping keep its electrical consumption and heat output relatively modest for a professional 28-interface managed switch.
TP-Link's current SG3428 V2.30 specification lists a maximum consumption of approximately 20.6W at 220V / 50Hz.
Power consumption can vary between hardware revisions, operating voltage and network configuration.
Important: The TL-SG3428 Is Not a PoE Switch
The 24 RJ45 Ethernet ports do not provide Power over Ethernet.
The switch can carry network data to devices such as:
- Wireless access points
- IP cameras
- VoIP phones
but those devices require their own compatible power supply, PoE injector or separate PoE switch.
When Should You Choose a PoE Version?
If you want the switch itself to power multiple access points, IP cameras or phones through Ethernet cables, consider an appropriate TP-Link PoE/PoE+ model such as a compatible SG3428MP-series switch instead.
Rackmountable Metal Chassis
The TL-SG3428 uses a durable metal enclosure measuring approximately:
- Width: 440mm
- Depth: 180mm
- Height: 44mm
The approximately 44mm height corresponds to a conventional 1U rackmount form factor.
19-Inch Rack Installation
TP-Link supplies a rackmount kit for installation into a compatible 19-inch network cabinet or rack.
Rubber feet are also included for suitable desktop or shelf placement.
Internal 100–240V AC Power Supply
The SG3428 uses an integrated 100–240V AC, 50/60Hz power supply.
A separate external power brick is therefore not required for normal operation.
Suitable for Office Networks
The combination of 24 copper Gigabit Ethernet ports, four fibre SFP slots and advanced management functionality makes the TL-SG3428 particularly suitable for small and medium business networks.
A typical office installation could connect:
- Employee computers
- Printers
- Servers
- NAS storage
- Network controllers
- Separately powered wireless access points
while using fibre SFP interfaces to connect other network cabinets or switches.
Suitable for Schools and Education Networks
Schools, colleges and training environments can use VLANs to separate:
- Staff networks
- Student networks
- Guest connectivity
- Administration systems
- Server infrastructure
Omada centralised management can also simplify administration where compatible TP-Link switches and wireless access points are deployed across multiple classrooms or buildings.
Suitable for Hospitality
Hotels, restaurants and other hospitality businesses can use the SG3428 as part of a managed network incorporating separate staff, guest, VoIP and infrastructure VLANs.
Functions such as QoS, authentication, Port Isolation and centralised Omada management are particularly useful in shared-network environments.
Suitable for CCTV Networks
The switch can also form part of an IP surveillance network where cameras receive power separately.
VLAN segmentation, Port Security, bandwidth control and high port density can help administrators organise CCTV traffic separately from business computers and guest networks.
Remember that this model does not supply PoE power to cameras.
Suitable for Fibre-Linked Network Cabinets
The four Gigabit SFP slots make the TL-SG3428 particularly useful where different network cabinets need to be connected using fibre.
Fibre may be preferred between floors or buildings where copper cable distance, electrical isolation or electromagnetic interference is a concern.

Important SFP Compatibility Note
The TL-SG3428 uses Gigabit SFP interfaces rather than 10Gbps SFP+. Select compatible SFP modules according to the required network speed, fibre type, wavelength, connector type and link distance.
TP-Link's current SG3428 specification lists the SFP interfaces as 100/1000Mbps.
Important PoE Note
The TL-SG3428 is a non-PoE managed switch. It does not supply electrical power through its RJ45 Ethernet ports.
PoE-powered wireless access points, cameras and phones require another suitable power source.
Important Omada Management Note
The switch can operate independently without an Omada Controller. However, Omada App and centralised cloud management require a compatible Omada Controller, while Zero-Touch Provisioning requires the Omada Cloud-Based Controller.
Important Hardware Revision Note
TP-Link has released multiple hardware revisions under the TL-SG3428 / SG3428 name. Core functions such as 24 Gigabit RJ45 ports, four Gigabit SFP slots, 56Gbps switching capacity and fanless operation remain consistent, but some capacity limits and advanced functions vary between revisions.
For example, older TL-SG3428 V1 specifications list an 8K MAC address table and 16 IPv4/IPv6 interfaces, while TP-Link's current SG3428 V2.30 specification lists a 16K MAC table, 12Mbit packet buffer and 128 IP interfaces.
Check the hardware revision printed on the physical switch where a revision-specific feature or maximum capacity is critical.
Important Routing Note
The TL-SG3428 is an L2+ managed switch with static routing. It should not automatically be treated as a replacement for an Internet router, firewall or Omada security gateway.
WAN connectivity, NAT, VPN gateway functionality and advanced firewall services normally require an appropriate separate router or gateway.
Why Choose the TP-Link TL-SG3428?
The TP-Link TL-SG3428 / SG3428 is a strong choice for businesses that need many reliable Gigabit Ethernet connections together with professional network management and flexible fibre connectivity.
Its 24 Gigabit RJ45 ports and four Gigabit SFP slots provide a practical combination for desktop devices and fibre-linked network infrastructure, while the 56Gbps switching capacity and 41.66Mpps forwarding rate provide the performance required for a busy wired LAN.
Advanced capabilities including VLANs, static routing, LACP, STP/RSTP/MSTP, ACLs, QoS, IGMP/MLD Snooping, 802.1X, DHCP Snooping, ARP Inspection, ERPS and IPv6 provide far greater network control than an unmanaged or basic smart switch.
Integration with TP-Link Omada SDN makes the SG3428 particularly useful for organisations already using Omada gateways and access points, while standalone Web, CLI, SNMP and RMON management ensures it can also be deployed in conventional managed networks.
The fanless 1U metal chassis provides silent operation, making the switch suitable for offices and other environments where an audible cooling fan would be undesirable.
Choose the TP-Link TL-SG3428 if you need a professional 24-port Gigabit L2+ managed switch with four Gigabit SFP fibre uplinks, Omada SDN support, advanced VLAN and security functions, static routing and silent fanless operation.

PoE-powered wireless access points, IP cameras, VoIP phones and other PoE devices require a suitable external injector, separate PoE switch or another compatible power source.
Important SFP vs SFP+ Note
The four fibre interfaces are Gigabit SFP slots, not 10Gbps SFP+ slots. Current SG3428 specifications list support for 100/1000Mbps SFP operation.
If you require 10Gbps fibre or DAC uplinks, the TL-SG3428X / SG3428X is the separate model designed with four 10Gbps SFP+ interfaces.
Important SFP Transceiver Note
SFP optical transceivers are not included. Select modules according to the required fibre type, connector, wavelength, speed and link distance.
Always check TP-Link compatibility information before purchasing third-party SFP modules.
Important Hardware Revision Note
TP-Link has released multiple hardware revisions under the TL-SG3428 / SG3428 product name. Core hardware specifications such as 24 Gigabit RJ45 ports, four Gigabit SFP slots, 56Gbps switching capacity, 41.66Mpps forwarding and fanless operation remain consistent across current revisions, but some secondary specifications and management limits vary.
For example, TP-Link's TL-SG3428 V2.20 documentation lists 16 IP interfaces, while TP-Link's newer live SG3428 specification lists up to 128 IPv4/IPv6 interfaces.
The secondary console connection can also vary: V2.20 / V2.30 models use Micro-USB, while newer V2.40 documentation lists USB Type-C.
When a revision-specific function is critical, check the hardware-version label printed on the physical switch before deployment.
Important MAC Table and Packet Buffer Note
Current SG3428 V2.x hardware specifications list a 16K MAC address table and 12Mbit packet buffer. Older TL-SG3428 revisions may use lower values. These specification changes are related to hardware revision rather than a different basic product name.
Important Omada Controller Note
The switch can operate without an Omada Controller using standalone Web, CLI, SNMP and RMON management.
Omada App and centralised cloud management require a compatible Omada Controller. Zero-Touch Provisioning requires the Omada Cloud-Based Controller.
Important Routing Note
The TL-SG3428 is an L2+ managed switch with static routing functionality. It is not a direct replacement for an Internet router, security gateway or firewall.
WAN connectivity, NAT, VPN gateway services and advanced firewall functions normally require a separate compatible router or Omada gateway.
Important Firmware Note
Advanced functions such as ERPS, OAM, DDM, sFlow, ISP features and some Omada-managed functions can depend on hardware revision and installed firmware.
Only install firmware specifically intended for the hardware version printed on the product label.
Model Identification Note

28. Does the TP-Link TL-SG3428 support VLANs?
Yes. The switch includes extensive VLAN functionality such as 802.1Q tagged VLANs, MAC VLAN, protocol VLAN, Private VLAN, GVRP, QinQ and Voice VLAN.
29. How many VLANs can the SG3428 support?
Current SG3428 specifications list support for up to approximately 4,000 VLAN groups, providing considerably more segmentation capacity than most small-business and home-lab deployments require.
30. Can I separate guest, IoT, CCTV, staff and server devices using VLANs?
Yes. You can create separate VLANs for networks such as staff, guests, IoT devices, CCTV cameras, VoIP phones, servers and network-management equipment. Your routing and ACL configuration then determines which networks may communicate with each other or access the internet.
31. Can the TL-SG3428 route traffic between VLANs?
Yes. The SG3428 is an L2+ switch with static Layer 3 routing features. It can create IP interfaces for VLANs and route traffic between them. If those VLANs need isolation, suitable ACL rules should also be configured.
32. How many static routes does the TP-Link SG3428 support?
The current SG3428 specification lists support for up to 48 IPv4/IPv6 static routes.
33. Does the SG3428 have its own DHCP server?
Yes. Current SG3428 specifications include DHCP Server, DHCP Interface Relay, DHCP VLAN Relay and DHCP L2 Relay functionality.
34. Why do devices on my new VLAN fail to receive an IP address?
This is a common VLAN configuration question. Creating a VLAN on the switch does not automatically guarantee that clients have a suitable DHCP service and internet gateway. The VLAN must have access to a DHCP server for its subnet, either on the SG3428 where appropriately configured or through a VLAN-aware router/server using DHCP relay or suitable routing.
35. Can I use the TL-SG3428 with an ASUS, pfSense, OPNsense, UniFi or other non-Omada router?
Yes. You do not need an Omada router. The SG3428 can work with third-party routers and firewalls. However, if the router is expected to provide routing, internet access or DHCP for multiple VLANs, it must support the necessary VLAN and routing configuration.
36. Can the SG3428 replace my internet router or firewall?
No, not in a typical internet deployment. It provides managed switching and static routing but is not a full WAN security gateway. NAT, broadband authentication, VPN gateway services and stateful firewall functionality normally require a separate router or firewall.
37. Does the SG3428 support ACLs to isolate VLANs or devices?
Yes. The switch supports MAC ACLs, IPv4 ACLs, IPv6 ACLs, time-based ACLs and combined ACLs. Rules can be used to permit, deny, redirect or rate-limit selected traffic and can be applied to ports or VLANs.
38. Can I allow one VLAN to access a printer while blocking access to another VLAN?
Yes. With suitable routing and ACL rules, you can permit selected traffic between networks while blocking other communication. For example, a trusted VLAN could be allowed to reach a printer VLAN while an IoT or guest VLAN remains isolated.
39. What security features does the TP-Link SG3428 provide?
Security features include IP-MAC-Port Binding, DHCP Snooping, ARP Inspection, Source Guard, ACLs, port security, DoS defence, storm control, 802.1X, MAC-based authentication, RADIUS, TACACS+, port isolation and secure HTTPS/SSH management.
40. Does the SG3428 support QoS?
Yes. The switch provides L2/L3/L4 Quality of Service, eight priority queues, 802.1p CoS/DSCP prioritisation, rate limiting and configurable queue scheduling. These functions can help prioritise VoIP, video or other latency-sensitive traffic.
41. Does the TL-SG3428 support IGMP Snooping?
Yes. IGMP Snooping helps manage IPv4 multicast traffic so multicast streams are forwarded only to ports that require them instead of being unnecessarily flooded across the VLAN. MLD Snooping is also supported for IPv6 multicast.
42. Does the SG3428 support LACP Link Aggregation?
Yes. The switch supports static link aggregation and IEEE 802.3ad LACP. LACP can combine compatible physical connections into a logical link for increased aggregate bandwidth and redundancy.
43. Can I use LACP between two SG3428 switches?
Yes. Multiple compatible Ethernet or SFP links can form an LACP trunk between managed switches. A single connection or file transfer normally remains limited by one member link, but multiple simultaneous flows can use the combined aggregate capacity.
44. Can several SG3428 switches be hardware-stacked as one switch?
The SG3428 is not advertised as a hardware-stacking switch. Multiple units can be interconnected, aggregated using LACP and centrally managed through Omada, but they remain separate physical switches.
45. Does the SG3428 support STP, RSTP and MSTP?
Yes. The switch provides Spanning Tree functionality to help prevent network loops when redundant Ethernet paths exist. Related loop-detection and protection functions are also supported.
46. What is ERPS and does the SG3428 support it?
Yes. Ethernet Ring Protection Switching (ERPS) is designed to provide rapid recovery when a link fails in a configured Ethernet ring. It can be useful in business, campus and multi-switch infrastructure.
47. Does the TP-Link SG3428 support IPv6?
Yes. The switch supports dual IPv4/IPv6 operation, IPv6 interfaces, static IPv6 routing, IPv6 ACLs, DHCPv6-related functions, IPv6 neighbour discovery, MLD Snooping and management services over IPv6.
48. Does the SG3428 support port mirroring?
Yes. Port mirroring allows selected network traffic to be copied to another interface for monitoring or troubleshooting using packet-analysis and network-diagnostic tools.
49. Does the TL-SG3428 have Ethernet cable diagnostics?
Yes. TP-Link includes cable diagnostics among the SG3428 management functions, which can help identify certain Ethernet-cabling problems during network troubleshooting.
50. What can I connect to the four SFP slots?
The Gigabit SFP slots can connect suitable fibre transceivers or compatible Gigabit RJ45 SFP modules. Typical uses include fibre links to another switch, a network cabinet, server, router or media-converter installation.
51. Which TP-Link multimode fibre module can I use with the SG3428?
A suitable option is the TP-Link SM311LM / TL-SM311LM Gigabit multimode SFP module. It uses an LC connection and is designed for Gigabit fibre links over compatible multimode fibre, with current TP-Link documentation listing distances up to approximately 550m.
52. Which TP-Link single-mode fibre module can I use with the SG3428?
The TP-Link SM311LS / TL-SM311LS is a Gigabit single-mode LC SFP module suitable for longer-distance fibre links. Exact supported distance can vary by module revision, so check the current transceiver specification before deployment.
53. Can I convert an SFP slot into a normal RJ45 Gigabit Ethernet port?
Yes, with a compatible 1000BASE-T RJ45 SFP module such as TP-Link's SM331T where compatibility with the particular switch revision is confirmed. This can convert an SFP position into a copper Gigabit RJ45 connection.
54. Can I use third-party SFP modules with the TL-SG3428?
Some standards-compliant third-party SFP modules may work, but operation is not guaranteed simply because the module physically fits. TP-Link recommends using compatible TP-Link/Omada modules for the most predictable interoperability.
55. Can I use the SG3428 to connect network cabinets or buildings with fibre?
Yes. Fibre uplinks are one of the main advantages of the four SFP slots. Suitable multimode or single-mode fibre modules can connect switches over distances that would be impractical for ordinary copper Ethernet and can provide electrical isolation between network locations.
56. TL-SG3428 vs TL-SG3428X – what is the difference?
The key difference is uplink speed. The TL-SG3428 has four Gigabit SFP slots, while the TL-SG3428X has four 10Gbps SFP+ slots. The standard SG3428 is suitable when Gigabit fibre uplinks are sufficient. Choose the SG3428X when servers, NAS devices or switch uplinks require 10Gbps bandwidth.
57. TL-SG3428 vs SG3428MP – which should I choose?
Choose the standard SG3428 when you need managed Gigabit switching and fibre uplinks but do not require PoE. Choose a suitable SG3428MP model when the switch also needs to provide PoE/PoE+ power to wireless access points, IP cameras or VoIP phones. PoE versions are larger, consume more power and use active cooling.
58. What warranty does the TP-Link TL-SG3428 have in the UK?
TP-Link UK currently categorises eligible SMB products under its Limited Lifetime Warranty, subject to TP-Link's UK warranty terms, authorised-reseller requirements, proof of purchase and product eligibility. TP-Link notes that products declared End of Life move to the applicable EOL warranty terms.
59. Why do TL-SG3428 specifications sometimes differ between websites?
TP-Link has released several hardware revisions under the TL-SG3428 / SG3428 name. Core features such as 24 Gigabit RJ45 ports, four Gigabit SFP slots, 56Gbps switching capacity and fanless operation remain consistent, but limits such as MAC-table size, packet buffer, IP-interface count and secondary console connector can differ between revisions. Check the hardware-version label on the physical switch when a revision-specific feature is important.
60. Who is the TP-Link TL-SG3428 best for, and who should choose another switch?
The TL-SG3428 is particularly suitable for small and medium businesses, offices, schools, advanced home networks and home labs that need 24 managed Gigabit Ethernet ports, Gigabit fibre uplinks, silent fanless operation, VLANs, LACP, ACLs, static routing and Omada management. Choose another switch if you need integrated PoE, native 2.5GbE, 10Gbps SFP+ uplinks, hardware stacking or substantially more advanced dynamic Layer 3 routing.
