The DGS-2000 Series provide a diverse range of Gigabit port densities to accommodate various needs of enterprise access layer connectivity. With options such as PoE to conveniently power edge devices, SFP ports to extend network connectivity, advanced Layer 2 functionalities, and Layer 3 Lite manageability, the DGS-2000 Series is the ideal choice for any enterprise access layer deployment. Ultra High Availability For mission critical environments, the DGS-2000 series supports IGMP snooping, port mirroring, Spanning Tree Protocol (STP), and Link Aggregation Control Protocol (LACP). The IEEE 802.3x Flow Control function allows servers to directly connect to the switch for fast, reliable data transfers. Network maintenance features include loopback detection and cable diagnostics. Loopback detection significantly speeds up troubleshooting by automatically detecting and terminating switching loops. The cable diagnostics feature, designed primarily for administrators and customer service representatives, determines the cable quality and quickly discovers errors, allowing for effortless diagnostics and maintenance. An Added Line of Defense Against Attacks? Defend your network with D-Link's innovative Safeguard Engine to neutralize threats such as malicious network flooding attacks, ARP spoofing, and bogus DHCP IP addressing. Compatible with 802.1X RADIUS server applications, port-based and host-based authentication are applied through the Access Control List (ACL) to enhance network security.? Seamless Integration for All Access Layer Requirements The DGS-2000 Series includes a wide variety of port and media types, including 10/100/1000BASE-T RJ-45 ports, 100/1000 Mbps GbE/SFP combo ports, and 100/1000 Mbps SFP ports. The DGS-2000-10, DGS-2000-26, DGS-2000-10P and DGS-2000-10MP models feature two 100/1000 Mbps SFP ports, while all other DGS-2000 Series models feature two or four GbE/SFP combo ports, allowing you to choose the most suitable media
