Product Description













TL-SL3428 is TP-LINK for departmental network development Gigabit uplink layer 2 Network Ethernet switch products, provide 24 10 / 100M adaptive RJ45 port, four 10/100/1000M adaptive RJ45 port of and two Gigabit SFP (Mini GBIC) optical fiber module expansion slots, support all port line speed forwarding, while providing the perfect security and QoS strategy, support a variety of flexible and convenient way to manage the, suitable for enterprise, industrial park and campus building economic and efficient network.

Line speed forwarding, flexible expansion

TL-SL3428 provides 24 10 / 100M adaptive RJ45 port, two 10/100/1000M adaptive RJ45 port of and two Gigabit SFP (Mini GBIC) optical fiber module expansion slots, support all port line speed forwarding and have great data forwarding capability. Rich port type can meet the formation of departmental 100m network, also can meet the formation of Gigabit backbone, hundreds of megabytes access network, users can also according to the connection distance and the equipment selection and Gigabit copper or fiber-optic Gigabit backbone lines and strong network flexibility.

Good security strategy

TL-SL3428 provide perfect security strategy, support IP//Port/VID binding of four yuan, the ARP attack door, thoroughly solve the network ARP spoofing attacks; port security support, limited port address learning number, effective defense address to attack; support for DoS attack defense, effective protection of the Internet security.

High performance and high reliability

Support link aggregation, allows configuration of up to 10 polymerization group, each group of up to 8 ports, can fully meet user demand for high bandwidth, and realize the link backup. At the same time support the STP/RSTP/MSTP two layer link protection technology, in order to avoid the link backup network loop realized at the same time, improve the fault tolerance capability, ensure high network reliability.

Strong business support ability

Support IGMP Snooping, can avoid a large number of broadcast and multicast data by occupation of cyber source video on demand, and satisfy the applications such as video conferencing. Support 802.1p and DSCP priority based QoS policy, each port support four priority queues, the SP+WRR sp (strict priority scheduling), WRR (weighted round robin scheduling) and three kinds of queue scheduling algorithm, different network traffic data can according to priority into port output queue to achieve on-demand forwarding.

Flexible management and maintenance

Support SNMP (simple network management) V1/V2. CLI command line management, support CLI over telnet session and CLI over SSH session. Provide Web management, make equipment management more convenient and flexible.

Support cable detection (VCT) function, convenient and fast detection of fault. Support system log, timely recording of system events, to facilitate the administrator confirm possible causes.
