D-Link's DGS-3120 xStack Series are enhanced L2 access stackableswitches designed to connect end-users in a secure SMB or enterprisenetwork. These switches support physical stacking, multicast andenhanced security, making them an ideal Gigabit access layer solution. The DGS-3120-24SC provides 16 SFP Gigabit ports and 8 combo1000Base-T/SFP ports. This switch is also equipped with an SD Card slot, allowing the user to boot images and upload configuration filesdirectly from an SD Card. Standard and Enhanced Images The DGS-3120 Series is embedded with two different software images-Standard Image (SI) and Enhanced Image (EI). The Standard Imageprovides sophisticated features for small and medium businesses, including advanced Quality of Service (QoS), traffic shaping, L2multicasting, and robust security features. The Enhanced Image supportsERPS, Double VLAN (Q-in-Q), Ethernet OAM, Static Route, IMPB, sFlow, IPv6 features which are suitable for the next generation IPv6 networksor triple play applications in Metro Ethernet. Enhanced Network Reliability The DGS-3120 Series targets small and medium businesses that require ahigh level of network security and maximum uptime. All the models inDGS-3120 Series support an external redundant power supply so thatcontinued operation can be assured. They also include other features, such as Spanning Tree, Rapid Spanning Tree and Multiple Spanning Tree, Loopback Detection, and Broadcast Storm Control, which enhance networkresilience. The Ethernet Ring Protection Switching (ERPS) functionminimises the recovery time in case of a loop failure. For load sharingand redundancy backup in switch cascading/server attachmentconfiguration, the DGS-3120 Series provides dynamic port trunking. Comprehensive Security D-Link's DGS-31 20 Series provides users with the latest securityfeatures such as Multi-layer and Packet Content Access Control Lists(ACL), Storm Control, and IP-MAC-Port Binding (IMPB) with DHCP Snooping. The IP-MAC-Port Binding feature allows administrators to bind a sourceIP address with an associated MAC and also define the port number toenhance user access control. With the DHCP Snooping feature, the switchautomatically learns IP/MAC pairs by snooping DHCP packets and savingthem to the IMPB white list. In addition, the D Link Safeguard Engineidentifies and prioritises CPU interested packets to prevent malicioustraffic from interrupting normal network flows, and to protect switchoperation. Identity Driven Network Policies The DGS-3120 Series supports authentication mechanisms and securitypolicies that can be applied individually to each connected host. Inaddition, the switch also supports Microsoft® NAP (Network AccessProtection). NAP is a policy enforcement technology that allowsadministrators to protect network assets from unhealthy computers byenforcing compliance with network health policies. Traffic Management for Triple Play D-Link's DGS-3120 Series implements a rich set of multilayer QoS/CoSfeatures to ensure that critical network services like VoIP, videoconference, IPTV and IP surveillance are served with high priority. TheTraffic Shaping features guarantee bandwidth of these services when thenetwork is busy. With L2 Multicast support, the DGS-3120 shows itsability to handle growing IPTV applications. Proactive, Effective Network Management To uphold users’ Service Level Agreements (SLA), service providersmust reduce the Mean Time to Repair (MTTR) and increaseserviceavailability. Ethernet OAM features address these challenges and enableservice providers to offer carrier-grade services. The DGS-3120 Seriessupports industry-standard OAM tools, including IEEE 802.3ah, IEEE802.1ag, and ITU-T Y. 1731. Connectivity Fault Management (CFM)provides tools to monitor and troubleshoot end-to-end Ethernet networks, allowing service providers to check connectivity, isolate networkissues, and identify customers affected by network issues. IPv6 Technology The DGS-3120 Series is fully compliant with the future IPv6 networks. It supports IPv6-based security functions to protect the network fromillegal IPv6 clients. The DGS-3120 Series has been certified with IPv6Ready Logo Phase 2 from the IPv6 forum, a worldwide IPv6 advocacyconsortium. The IPv6 Ready Logo Program provides conformance andinteroperability of IPv6 products. Manageability

D-Link’s Single IP Management (SIM) simplifies and speeds upmanagement tasks, allowing multiple switches to be configured, monitoredand maintained from any workstation running a web browser through oneunique IP address. This virtual stack is managed as a single object, having all units maintained by one IP address. The DGS-3120 Series alsosupports standard-based management protocols such and secureauthentication. D-Link Green Technology D-Link is striving to take the lead in developing innovative andpower-saving technology that does not sacrifice operational performanceor functionality. The DGS-3120 Series implements the D-Link GreenTechnology, which includes a power saving mode, smart fan, reduced heatdissipation, and cable length detection. The power saving featureautomatically powers down ports that have no link or link partner. TheSmart Fan feature allows for the built-in fans to automatically turn onat a certain temperature, providing continuous, reliable and ecofriendly operation of the switch.
