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 xStack DGS-3420 series of next generation Layer 2+ Gigabit switches delivers performance, flexibility, security, multi-layer QoS, and accessibility, along with redundant power solutions for SMBs and enterprises. With high Gigabit port densities, Gigabit SFP, 10-Gigabit SFP+ support, and advanced software solutions, these switches can act as either departmental access layer devices or aggregation switches to form a multilevel network structured with backbone and centralized high-speed servers.


Features Summary

  • Unparalleled flexibility
    Easily deployed and simple to manage, the DGS-3420 can be stacked with any switch that supports D-Link's Single IP Management to form a multi-level network structured with backbone and centralized high-speed servers. The virtual stack can include units located anywhere on the same network domain, and uses optional 10-Gigabit uplinks to move intra-stack traffic at 20 Gbps full duplex speeds.
  • Redundant ring stacking
    Alternatively, depending on whether linear or fault tolerant ring stacking is implemented, users can use one or two 10-Gigabit SFP+ ports to create a physical stack. 12 units or 576 Gigabit ports can be configured for a stack using direct attach cables to provide high-bandwidth on the DGS-3420 series with cost efficiency.
  • Security, performance and availability
    The DGS-3420 series provides a complete set of security features including L2/L3/L4 multi-layer Access Control Lists and 802.1X user authentication via TACACS+ and RADIUS servers. The DGS-3420 series offers extensive VLAN support including GVRP and 802.1Q VLAN to enhance security and performance. A robust set of L2/L3/L4 QoS/CoS solutions help ensure that critical network services such as VoIP, ERP, Intranet, and video conferencing are served with proper priority. The series also provides D-Link's Safeguard Engine to increase the switch's reliability, serviceability, and availability to prevent malicious flooding traffic caused by worms or virus infections.
  • IPv6 technology
    The DGS-3420 series also features comprehensive IPv6 support, including IPv6 tunnel, ICMPv6, DHCPv6, RIPng, and more. With 10-Gigabit connectivity and IPv6 support, the series enables you to future-proof your network for cost efficiency and longevity while meeting the requirements that future IPv6 capable network devices require.
  • D-Link Green technology
    D-Link is striving to take the lead in developing innovative and power-saving technology that does not sacrifice operational performance or functionality. The DGS-3420 series implements D-Link Green technology, which includes a power saving feature, smart fan design, reduced heat dissipation, and cable length detection. The power saving feature automatically powers down ports that have no link or link partner. The smart fan design allows the built-in fans to automatically turn on only at a certain temperature, providing continuous, reliable and eco-friendly operation of the switch.
