Key Features
-
24 x 10/100/1000BASE-T Gigabit Ports: High-speed connectivity for computers, servers, IP cameras, wireless access points, and network devices
-
4 x 10G SFP+ Uplink Ports: Flexible fiber optic uplinks using multimode or single-mode SFP transceivers for scalable network expansion
-
128 Gbps Switching Capacity: High-performance throughput with 95.23 Mpps forwarding rate for demanding network environments
-
Layer 3 Lite Static Routing: Enables inter-VLAN routing and network segmentation for increased efficiency
-
6kV Surge Protection: Built-in surge protection on all Gigabit Ethernet ports safeguards against electrical surges and lightning strikes
-
Dual Image & Configuration: Reduces downtime with dual software images and configuration files for seamless updates and troubleshooting
Advanced Management and Security
The DGS-1250-28X provides comprehensive management options including a full Command Line Interface (CLI) via dedicated console port, intuitive web-based GUI with 11 web languages, and SNMP support for remote network management. Advanced security features include 802.1X authentication, Access Control Lists (ACL) at Layer 2/3/4, ARP spoofing prevention, IP-MAC-Port Binding (IMPB), DHCP server screening, and D-Link's Safeguard Engine to protect against malicious traffic flooding and denial-of-service attacks.
Enterprise-Grade Layer 2 & Layer 3 Features
Equipped with a complete lineup of Layer 2 switching features including IGMP snooping, port mirroring, Link Aggregation Control Protocol (LACP) supporting up to 8 groups, and Spanning Tree Protocol (STP/RSTP/MSTP) for network redundancy and loop prevention. Layer 3 Lite capabilities provide IPv4/IPv6 static routing, IP interfaces, and IPv6 Neighbor Discovery for efficient network segmentation and communication between VLANs.
Quality of Service & Traffic Management
The switch supports 802.1p Quality of Service (QoS), DSCP marking, and bandwidth control to prioritize critical network traffic. Auto Voice VLAN automatically detects and segments VoIP traffic for enhanced security and quality, while Surveillance Mode with ONVIF support streamlines IP camera deployment by automatically identifying and prioritizing video traffic in dedicated VLANs.
Network Maintenance & Diagnostics
-
Loopback Detection: Automatically detects and shuts down switching loops to prevent network disruption
-
Cable Diagnostics: Quickly identifies cable quality issues and errors for swift troubleshooting
-
D-Link Network Assistant (DNA): Free utility for discovering and managing multiple D-Link switches within the same network segment
-
IEEE 802.3x Flow Control: Enables fast, reliable data transfers when connecting servers directly to the switch
Energy Efficiency
Compliant with IEEE 802.3az Energy-Efficient Ethernet (EEE) standards, the DGS-1250-28X features a smart 5-speed fan that automatically adjusts for optimal cooling while minimizing power consumption and noise. The switch intelligently adjusts power usage based on cable length and link status, reducing energy costs without sacrificing performance.
