TP-LINK TL-SG3428 28-port All gigabit managed switch 24GE 4SFP layer 2

TP-LINK newly developed 3 series all-gigabit network management switch, using a new generation of high-performance hardware and software platform, providing flexible and cost-effective all-gigabit access and upstream ports, supporting a complete security protection mechanism and perfect ACL /QoS strategy and flexible VLAN function, easy to manage and maintain, meet users' requirements for easy management of network equipment, high security and low cost networking, suitable for campus, hotel and enterprise campus network access, aggregation of multiple application scenarios.

Full Gigabit port

• The whole series supports the combination of "Ethernet port + optical port", which is convenient for users to flexibly network and meet the networking needs of various scenarios;
• Provide 8/16/24/48 multi-standard port products, all ports have Gigabit wire-speed forwarding capabilities to meet the needs of different users.

Strong business processing capabilities

• Support IEEE 802.1Q VLAN, users can flexibly divide VLAN according to demand.
• Supports voice VLAN, configures QoS parameters for voice data streams, improves the transmission priority of voice data streams, and guarantees call quality.
• Support QoS, support three priority modes based on port, 802.1P and DSCP and four queue scheduling algorithms: Equ, SP, WRR, SP+WRR.
• Support ACL, filter packets by configuring matching rules, processing operations, and time permissions, and provide flexible security access control strategies.
• Support IGMP V1/V2 multicast protocol, support IGMP Snooping, meet multi-terminal high-definition video surveillance and video conference access requirements.
• Support multicast VLAN, multicast filtering, efficient data transmission, save network bandwidth and reduce network load.
• Support port monitoring, copy the data packet of the monitored port to the monitoring port to realize network monitoring.

Complete security protection mechanism

• Support IP address, MAC address, VLAN and port quaternary binding to filter data packets.
• Supports ARP protection to protect against gateway spoofing and man-in-the-middle attacks such as ARP spoofing and ARP flood attacks common in LANs.
• Support IP source protection to prevent illegal address spoofing including MAC spoofing, IP spoofing, and MAC/IP spoofing.
• Support DoS protection, support Land Attack, Scan SYNFIN, Xmascan, Ping Flooding and other attacks.
• Support 802.1X authentication, provide authentication functions for LAN computers, and control the authorization status of controlled ports according to the authentication results.
• Support port security, stop learning when the number of MAC addresses learned by the port reaches the maximum number, prevent MAC address attacks and control port network traffic.

Diverse reliability protection

• Supports STP/RSTP/MSTP spanning tree protocol to eliminate layer 2 loops and realize link backup.
• Supports spanning tree security features to prevent devices in the spanning tree network from being subjected to various forms of malicious attacks.
• Support static aggregation and dynamic aggregation, effectively increase link bandwidth, achieve load balancing, link backup, and improve link reliability.

PoE power supply function (only supported by PoE models)

• PoE models support IEEE 802.3af/at PoE power supply standards to meet the needs of PoE power supply in security monitoring, teleconferencing systems, wireless coverage and other scenarios.
• Supports setting the Web network management interface to control the power supply of the PoE port based on a user-defined time period.
• Support to configure the priority of PoE ports on the Web network management interface. When the remaining power is insufficient, the power supply of high priority ports is guaranteed first.
• The PoE output power of each port of the PoE model can reach up to 30W, and the user can set the maximum power that the port can provide on the Web network management interface.

Easy operation and maintenance

• Support Web network management, CLI command line (Console, Telnet), SNMP (V1/V2/V3) and other diverse management and maintenance methods.
• Support HTTPS, SSL V3, TLSV1, SSHV1/V2 and other encryption methods, management is more secure.
• Support RMON, system log, port traffic statistics, easy network optimization and transformation.
• Support cable detection, Ping detection and Tracert detection operations, easy analysis of faulty network nodes.
• Support LLDP, convenient for network management system to query and judge the communication status of the link.
• Support CPU monitoring, memory monitoring, Ping detection, Tracert detection, cable detection.
