TP-Link TL-SL2428P Smart PoE+ Switch Overview

The TP-Link TL-SL2428P delivers reliable managed switching with 24 10/100Mbps PoE+ ports and 4 gigabit uplinks for small to medium business networks. This metal rack-mountable switch provides 250W total PoE power budget, supporting IEEE 802.3at/af-compliant devices including wireless access points, IP cameras, and VoIP phones without additional power cabling.

Power Over Ethernet Capabilities

With 24 IEEE 802.3at/af-compliant PoE ports delivering up to 250W total power, this smart switch eliminates the need for separate power supplies for connected devices. Deploy IP surveillance cameras, wireless access points, and IP phones efficiently across your network infrastructure while maintaining centralized power management and monitoring.

Network Performance and Connectivity

The TL-SL2428P features 12.8 Gbps switching capacity and 9.5 Mpps packet forwarding rate. Four 10/100/1000Mbps RJ45 ports plus 2 combo SFP slots provide flexible gigabit uplink options for backbone connectivity. Support for jumbo frames up to 9216 bytes ensures efficient data transfer for demanding applications.

Layer 2 Management Features

This managed switch includes comprehensive layer 2 functionality: 802.1Q VLAN support for network segmentation, STP/RSTP/MSTP for redundant topology management, link aggregation for increased bandwidth, and port mirroring for traffic analysis. IGMP snooping optimizes multicast traffic delivery, while loop detection prevents network disruptions.

Quality of Service and Traffic Control

Advanced QoS features prioritize network traffic based on 802.1p CoS and DSCP values across 8 priority queues. Voice VLAN support ensures clear VoIP communication, while bandwidth control and storm protection maintain network stability under heavy load conditions. Port-based and flow-based rate limiting provides granular traffic management.

Security and Access Control

Enterprise-grade security includes 802.1X authentication, IP-MAC-Port binding, DHCP snooping, ARP inspection, and DoS defense. Access Control Lists (ACLs) based on MAC, IP, and packet content provide flexible policy enforcement. Static and dynamic port security supports up to 64 MAC addresses per port for controlled network access.

Management and Monitoring

Configure and monitor the TL-SL2428P through intuitive web GUI, CLI via Telnet/SSH, or SNMP v1/v2c/v3. Integration with TP-Link Omada SDN platform enables centralized cloud-based management across multiple sites. RMON support, system logging, and cable diagnostics simplify network troubleshooting and maintenance.
