TP-Link TL-SG3428 JetStream 24-Port Gigabit L2+ Managed Switch | 24× Gigabit RJ45, 4× Gigabit SFP, Static Routing, Omada SDN

TP-Link TL-SG3428 24-Port Gigabit L2+ Managed Switch

The TP-Link TL-SG3428 is a 24-port Gigabit managed switch designed for business networks, offices, campuses, hotels, retail environments and other professional networking deployments. It combines 24× 10/100/1000Mbps RJ45 ports with 4× Gigabit SFP slots, providing reliable copper connectivity together with fiber uplink options.

As part of the TP-Link JetStream switching platform, the TL-SG3428 provides advanced Layer 2 and Layer 2+ networking features including VLAN, static routing, link aggregation, QoS, ACL, STP/RSTP/MSTP, IGMP Snooping, DHCP Snooping and 802.1X authentication. The switch can also be integrated into the TP-Link Omada SDN ecosystem for centralized network management on supported hardware and software versions.

Key Features of TP-Link TL-SG3428

• 24× Gigabit RJ45 Ports: 24 auto-negotiating 10/100/1000Mbps Ethernet ports for PCs, servers, access points, IP phones and other network devices.
• 4× Gigabit SFP Slots: Dedicated 1000Mbps SFP interfaces for fiber uplinks and longer-distance network connections.
• 56Gbps Switching Capacity: Provides high-speed switching performance for demanding business networks.
• 41.66Mpps Forwarding Rate: Supports efficient packet forwarding across the network.
• L2+ Managed Switching: Advanced VLAN, QoS, security and static-routing functions.
• Static Routing: Enables internal traffic routing without requiring an external router for every network segment.
• Omada SDN Integration: Supported hardware versions can be centrally managed through the Omada ecosystem.
• Advanced Security: ACL, IP-MAC-Port Binding, Port Security, DHCP Snooping, Storm Control, DoS Defend and 802.1X/RADIUS authentication.
• Enterprise QoS: L2/L3/L4 QoS, 802.1p CoS, DSCP and multiple priority queues.
• Fanless Design: Designed for quiet operation in office and business networking environments.
• Rackmount Design: Standard 1U rackmount form factor for network cabinets.

24 Gigabit Ethernet Ports

The TL-SG3428 provides 24× 10/100/1000Mbps RJ45 ports. Each port automatically negotiates the appropriate Ethernet speed and supports Auto MDI/MDIX, making deployment straightforward without requiring crossover cables.

The Gigabit ports can be used for computers, servers, printers, IP phones, wireless access points, CCTV equipment and other Ethernet devices. The switch is particularly useful as an aggregation or access-layer switch in small and medium-sized business networks.

4× Gigabit SFP Fiber Uplinks

Four dedicated Gigabit SFP slots provide fiber connectivity for longer-distance uplinks or connections between network cabinets and buildings.

Compatible Gigabit SFP modules can be selected according to the required fiber type and transmission distance. These interfaces are 1Gbps SFP slots, not 10G SFP+ slots.

For a switch with 10G SFP+ uplinks, the TP-Link TL-SG3428X is a different model and should not be confused with the TL-SG3428.

Advanced VLAN and Network Segmentation

The TL-SG3428 supports IEEE 802.1Q VLAN and other VLAN features that allow administrators to logically separate users and services on the same physical network.

VLAN segmentation can be used for applications such as:

• Office users
• Guest networks
• IP phones and VoIP
• CCTV surveillance
• Wi-Fi access points
• Management networks
• Server and application networks

This makes the TL-SG3428 suitable for structured business networks where traffic separation and controlled access are important.

Static Routing for Internal Networks

The TL-SG3428 provides static routing functionality for internal network segmentation. Static routes can help direct traffic between different VLANs or IP subnets directly through the switch, reducing unnecessary traffic through an external router in suitable network designs.

This makes the switch more capable than a basic unmanaged Gigabit switch and useful in networks requiring controlled Layer 3 internal connectivity.

Security Features

Network security features help administrators control which users and devices can access different parts of the network. The TL-SG3428 supports features including:

• Access Control Lists (ACL)
• IP-MAC-Port Binding
• Port Security
• DHCP Snooping
• Storm Control
• DoS Defend
• 802.1X Authentication
• RADIUS Authentication
• VLAN-based traffic control

These functions are useful in business, education, hospitality and enterprise networks where unauthorized access and network abuse need to be controlled.

QoS for Voice and Video

The TL-SG3428 supports advanced Quality of Service functions to prioritize important traffic. L2/L3/L4 QoS can be used with traffic classification based on network parameters such as MAC address, IP address and TCP/UDP information.

QoS is particularly useful for VoIP, video conferencing, IPTV, surveillance and other latency-sensitive applications.

IGMP Snooping for Multicast Traffic

IGMP Snooping allows the switch to intelligently forward multicast traffic only toward ports that require it. This helps reduce unnecessary multicast traffic and is useful for IPTV, multicast video and other multicast-based applications.

Link Aggregation and Network Redundancy

The TL-SG3428 supports Link Aggregation Control Protocol (LACP) and static link aggregation. Multiple physical Ethernet links can be combined into a logical connection where supported by the connected network equipment.

This can increase aggregate bandwidth and provide additional resilience for suitable uplink designs.

Omada SDN Centralized Management

Supported versions of the TL-SG3428 can be integrated with the TP-Link Omada SDN platform. Omada provides centralized management for compatible switches, access points and gateways.

Depending on the controller and hardware version, administrators can manage network devices from a centralized interface, monitor network activity, configure devices and simplify deployment across multiple locations.

TP-Link India specifically lists Omada Cloud-Based Controller support for TL-SG3428 V2 and above, while Omada Hardware Controllers and the Omada Software Controller are also supported.

Standalone Management

The TL-SG3428 can also be managed independently without relying exclusively on cloud management. Management options include:

• Web-based GUI
• CLI through console and Telnet
• SNMPv1/v2c/v3
• RMON
• LLDP/LLDP-MED
• System logging
• SNTP
• CPU monitoring
• Cable diagnostics
• Dual image and dual configuration

TL-SG3428 vs TL-SG3428X

If your network requires only Gigabit fiber uplinks, the TL-SG3428 provides four Gigabit SFP slots. If you specifically require 10Gbps fiber uplinks for servers, NAS or high-speed aggregation, the TL-SG3428X is the more appropriate model.

Important Hardware Version Note

The TL-SG3428 is available in multiple hardware revisions. TP-Link’s current India documentation shows differences between V1 and V2-and-later versions, including MAC address table capacity and Omada cloud-management capabilities. Always verify the hardware version of the unit before matching firmware or confirming a version-specific feature.
