Overview

Range/Series Overview


IMPORTANT: This Range/Series overview section describes the range of which this product belongs. Features of different versions might be mentioned and may not apply to the specific product on this page. Please view Specs for specification of product.

The D-Link DGS-1250 Series Smart Managed Switches deliver real value as an Enterprise Access and Small-to-Medium Business (SMB) Access/Aggregation solution. They provide a range of physical interfaces (including a Console Port with full CLI), multiple management interfaces, 11 Web languages, QoS enablement, and Advanced Layer-2 with Lite Layer-3 features.

The DGS-1250 Series switches support 24 or 48 x 10/100/1000BASE-T ports, with each switch also supporting an additional 4 x 10G SFP+ ports for optical connections using multimode or single-mode SFP transceivers - enabling real network horsepower at a value price.


Features Summary

  • Easy maintenance, less downtime
    The DGS-1250 Series supports Dual Image and Dual Configuration functionality, as well as a Console Port, all of which make it easier to configure, troubleshoot, and make other changes without interfering with network operation, while full Command Line Interface (CLI) functionality enables remote configuration, without the need for the Internet. And if a network issue ever does occur, the supported Spanning Tree Protocols (STP/RSTP/MSTP) help keep things running without interruptions or downtime.
  • Quality of Service (QoS)
    Automatic Configuration
    The DGS-1250 Series supports Auto Voice VLAN and Surveillance Mode, which allow Voice and Video traffic to be automatically identified and handled differently from regular network traffic. Auto Voice VLAN detects Voice over IP (VoIP) traffic and automatically segments it from the rest of the network, increasing security and allowing Quality of Service (QoS) to be applied.
  • High PoE budget (370W)
    The DGS-1250 series offers Power-over-Ethernet (PoE), which simplifies deployment with IP cameras, VoIP phones, Wireless Access Points, and other powered devices. Using the switch's management interface, an administrator can control various PoE functions, such as remotely rebooting Cameras or Access Points, from anywhere on the network, including over the Internet. All PoE models support the IEEE 802.3af and 802.3at standards, and each PoE power budget varies per model.
  • Extensive management and advanced features
    The DGS-1250 Series comes with 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. The series also supports advanced features such as Static Routing, which allows for communication between different user groups in different VLAN segments in a network.
  • Management versatility
    The DGS-1250 Series comes with the D-Link Network Assistant (DNA) utility so admins can remotely control their network to the port level. DNA allows customers to easily discover multiple D-Link Smart Managed Switches within the same L2 network segment and display them onscreen for instant access.
