What This Product Does

Designed for workgroups and departments, TL-SL5428E from TP-LINK provides full set of layer 2 management features. It delivers maximum throughput where you need it — to high-performance workgroups at the edge of the network, or as a backbone for Fast Ethernet switches and high-speed servers indemanding small networks. Moreover, TL-SL5428E switch also comes equipped with 2 combo SFP slots, giving you greater network flexibility.

This TP-LINK L2 managed switch has robust security and management features. An advanced Access Control List (ACL, L2 to L4) and the TP-LINK strong safeguard provide security coverage from core to edge and protect against broadcast  storm, ARP and Denial-of-Service(DoS) attacks, etc. Quality of Service (QoS, L2 to L4) provides enhanced traffic management capabilities to move your data smoother and faster. Anymore, the easy-to-use web management interfaces, along with CLI, SNMP and RMON, mean faster setup and configuration with less downtime. For workgroup and departments requiring cost-sensitive Layer 2 Switch, and additional Gigabit capability, TP-LINK L2 fully managed Switch TL-SL5428E can provide you the ideal access-edge solution.

Non-Blocking Switching

The TP-LINK fully managed L2 switch TL-SL5428E provides non-blocking switching solution for a 10/100Mbps fast Ethernet connection. As to the switching capacity, TL-SL5428E has a non-blocking aggregated bandwidth of 12.8Gbps. It provides 24 10/100Mbps ports and 4 gigabit 10/100/1000BASE-T ports. In these gigabit copper ports, two of these ports are combo gigabit ports, which will be disabled if the corresponding 1000BASE-X SFP slots are used. It can give you greater network flexibility.

Virtual Stackable

IP Clustering allows up to 32 TL-SL5428E switches to be managed by a single IP, regardless of geographical locations. With all units identified by a single IP address, the stack could be configured, monitored, maintained as a single object.

Traffic running across units in this virtual stack utilizes full-duplex interfaces and network wires, eliminating costly and cumbersome cables, minimizing the impact of any single point of failure.

Comprehensive Security Strategy

Access Control Lists (ACL, L2 to L4) restrict access to sensitive network resources by denying packets based on source and destination MAC address, IP address, TCP/UDP ports and even VLAN ID. This is done by hardware, so switching performance would not be compromised.

Moreover, the TL-SL5428E switch supports 802.1X authentication, which is used in conjunction with a RADIUS server to require some authentication information before access to the network is allowed. And more, it supports Guest VLAN to enable the non-802.1X clients to access the specific network resource. In addition,IP-MAC-Port-VID Binding, Port Security, Storm control, DHCP Snooping and IP Source Guard support can protect against broadcast  storms, ARP and Denial-of-Service(DoS) attacks, etc. Regarding to the DoS defending, TL-SL5428E provides you some typical DoS attacks to select. You can protect these attacks more easily ever than before. TL-SL5428E will provide you robust security to the network.

Enterprise Level Manageability and Resiliency

TL-SL5428E supports various user-friendly standard management features,such as intuitive web-based Graphical User Interface(GUI)or industry-standard Command Line Interface(CLI), either administration traffic can be protected through SSL or SSH encryptions. SNMP (v1/2/3) and RMON support enables the switch to be polled for valuable status information and send traps on abnormal events. This sharing of vital management information saves time and money. With link aggregation, spanning tree protocol(STP/RSTP/MSTP)and virtual stack, a highly intelligent and scalable topology could be established, fulfilling the enterprise customers´ requirement of building a unified, resilient network.

Optimized Voice and Video Applications

To integrate voice, data and video service on one network, TL-SL5428E applies rich QoS policies. Administrator can designate the priority of the traffic based on a variety of means including IP or MAC address, TCP or UDP port number, etc, so voice and video are always clear, smooth and jitter free. In conjunction with the Voice VLAN the switch supporting, the voice applications will operate with much smoother performance.

For other multimedia-on-demand application such as IPTV, TL-SL5428E provides advanced features for easy stream management. For example, IGMP snooping ensures the switch intelligently forward the multicast  stream only to the appropriate subscribers while IGMP throttling & filtering restrict each subscriber on a port level to prevent unauthorized multicast  access.
