With high Gigabit port densities, Gigabit SFP, 10-Gigabit SFP+ support, and advanced\u003cbr\u003esoftware solutions, these switches can act as either departmental access layer devices or aggregation\u003cbr\u003eswitches to form a multilevel network structured with backbone and centralized high-speed servers.\u003cbr\u003eService providers can take advantage of the high SFP density switches (such as DGS-3420-28SC\/26SC) to structure the aggregation of Fiber to the Building (FTTB)\u003cbr\u003enetworks that are extended to the subscribers’ sites.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eUnparalleled Flexibility\u003c\/b\u003e\u003cbr\u003eEasily 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\u003cbr\u003esame network domain, and uses optional 10-Gigabit uplinks to move intra-stack traffic at 20 Gbps full duplex speeds.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eRedundant Ring Stacking\u003c\/b\u003e\u003cbr\u003eAlternatively, depending on whether linear or faulttolerant 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.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eSecurity, Performance \u0026amp; Availability\u003c\/b\u003e\u003cbr\u003eThe 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.\u003cbr\u003eThe 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,\u003cbr\u003eserviceability, and availability to prevent malicious flooding traffic caused by worms or virus infections. Bandwidth Control can be flexibly set for each port using pre-defined thresholds to assure a committed level of service for endusers. For advanced applications, flow-based bandwidth control allows easy fine-tuning of service types based on specific IP addresses or protocols.\u003cbr\u003e\u003cbr\u003eIPv6 Technology\u003cbr\u003eThe DGS-3420 Series also features comprehensive IPv6 support, including IPv6 Tunnel, ICMPv6, DHCPv6, RIPng, IPv4\/IPv6 dual stack, 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.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eD-Link Green Technology\u003c\/b\u003e\u003cbr\u003eD-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 power saving through link status, smart fan design, increased 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.\u003c\/p\u003e\u003c\/div\u003e\u003cdiv id=\"icepim-attributes\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\u003cth colspan=\"2\"\u003eManagement
