buy Switch TP-Link TL-SG3428 . The TL-SG3428 switch from TP-Link is a Layer 2 managed device designed for business networks requiring high speed and flexible connectivity. It features 24 RJ45 Gigabit Ethernet ports (10/100/1000 Mbps) and 4 Gigabit SFP slots, allowing fiber optic links for long-distance connections or link aggregation, offering a total switching capacity of 56 Gbit/s. Its MAC table with 8000 entries enables efficient address management and improves performance in large networks. The TL-SG3428 supports multiple IEEE standards such as 802.1Q for tagged VLANs, 802.1p for Quality of Service (QoS), 802.1x for network portal authentication, and redundancy protocols like 802.1w (RSTP) and 802.1s (MSTP), ensuring a robust, loop-free network topology. Its firmware offers static routing, strong security features, and support for QoS on layers L2, L3, and L4, enabling prioritization of critical traffic and overall performance optimization. Additionally, it integrates the Omada SDN platform for centralized management, facilitating remote administration and unified configuration in complex environments. The device includes dual console ports (RJ-45 and Micro-USB) and can be rack-mounted in a compact 1U form factor. Its black construction and approximate weight of 2.5 kg make it suitable for professional deployments in data centers or telecom cabinets. The power supply supports 220 V input, and the durable plastic design ensures longevity. Overall, the TP-Link TL-SG3428 is a versatile and efficient solution for corporate networks requiring high simultaneous connection capacity, advanced security, and centralized management, positioning it as a reliable device for medium to large infrastructures.

Omada creates a highly scalable network—all controlled from a single interface. Seamless wireless and wired connections are provided, ideal for use in hospitality, education, retail, offices, and more.Secure NetworkingSecurity features include IP-MAC-Port-VID Binding, Port Security, Storm Control, and DHCP Snooping to defend against a range of network threats. An integrated list of common DoS attacks is available, making it easier than ever to prevent them. Also, the Access Control Lists (ACL, L2 to L4) feature restricts access to sensitive network resources by denying packets based on source and destination MAC address, IP address, TCP/UDP ports, or VLAN ID. Users’ network access can be controlled via 802.1X authentication, which works with a RADIUS/Tacacs+ server to grant access only when valid user credentials are provided.Advanced QoSVoice and video traffic can be prioritized based on IP address, MAC address, TCP port number, UDP port number, and more. With QoS (Quality of Service), voice and video services remain smooth, even when bandwidth is in short supply.Abundant L2 and L2+ FeaturesA complete lineup of L2 features is supported including 802.1Q VLAN, Port Mirroring, STP/RSTP/MSTP, Link Aggregation Control Protocol, and 802.3x Flow Control. Advanced IGMP Snooping ensures the switch intelligently forwards multicast streams to only the appropriate subscribers, cutting out unnecessary traffic, while IGMP throttling & filtering restrict each subscriber on a port level to prevent unauthorized multicast access. Static Routing is a simple way of segmenting the network and internally routs traffic through the switch for improved efficiency.ISP FeaturessFlow, QinQ, L2PT PPPoE ID Insertion, and IGMP authentication features are provided, developed with service providers in mind. 802.3ah OAM and Device Link Detection Protocol (DLDP) offer easy monitoring and troubleshooting of Ethernet links.IPv6 SupportIPv6 functions such as Dual IPv4/IPv6 Stack, MLD Snooping, IPv6 ACL, DHCPv6 Snooping, IPv6 Interface, Path Maximum Transmission Unit (PMTU) Discovery and IPv6 Neighbor Discover guarantee your network is ready for the Next Generation Network (NGN) without upgrading your hardware.Enterprise Level Management FeaturesEasy to manage via an intuitive web-based Graphical User Interface (GUI) or an
