The DGS-3120 xStack Series are enhanced L2 access stackable switches designed to connect end-users in a secure SMB or enterprise network. These switches support physical stacking, multicast and enhanced security, making them an ideal Gigabit access layer solution. They are equipped with an SD Card slot, allowing the user to boot images and upload configuration files directly from an SD Card.

The DGS-3120 Series is embedded with two different software images - Standard Image (SI) and Enhanced Image (EI). The Standard Image provides sophisticated features for small and medium businesses, including advanced Quality of Service (QoS), traffic shaping, L2 multicasting, and robust security features. The Enhanced Image supports ERPS, Double VLAN (Q-in-Q), Ethernet OAM, Static Route, IMPB, sFlow, IPv6 features which are suitable for the next generation IPv6 networks or triple play applications in Metro Ethernet.

The DGS-3120 Series targets small and medium businesses that require a high level of network security and maximum uptime. All the models in DGS-3120 Series support an external redundant power supply so that continued 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 network resilience. The Ethernet Ring Protection Switching (ERPS) function minimizes the recovery time in case of a loop failure. For load sharing and redundancy backup in switch cascading/server attachment configuration, the DGS-3120 Series provides dynamic port trunking.

The DGS-3120 Series provides users with the latest security features 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 source IP address with an associated MAC and also define the port number to enhance user access control. With the DHCP Snooping feature, the switch automatically learns IP/MAC pairs by snooping DHCP packets and saving them to the IMPB white list. In addition, the D-Link Safeguard Engine identifies and prioritizes "CPU interested" packets to prevent malicious traffic from interrupting normal network flows, and to protect switch operation.

The DGS-3120 Series supports authentication mechanisms and security policies that can be applied individually to each connected host. In addition, the switch also supports Microsoft NAP (Network Access Protection). NAP is a policy enforcement technology that allows administrators to protect network assets from unhealthy computers by enforcing compliance with network health policies.

The DGS-3120 Series implements a rich set of multilayer QoS/CoS features to ensure that critical network services like VoIP, video conference, IPTV and IP surveillance are served with high priority. The Traffic Shaping features guarantee bandwidth of these services when the network is busy. With L2 Multicast support, the DGS-3120 shows its ability to handle growing IPTV applications.

To uphold users' Service Level Agreements (SLA), service providers must reduce the Mean Time to Repair (MTTR) and increase service availability. Ethernet OAM features address these challenges and enable service providers to offer carrier-grade services. The DGS-3120 Series supports 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 network issues, and identify customers affected by network issues.

The DGS-3120 Series is fully compliant with the future IPv6 networks. It supports IPv6-based security functions to protect the network from illegal IPv6 clients. The DGS-3120 Series has been certified with IPv6 Ready Logo Phase 2 from the IPv6 forum, a worldwide IPv6 advocacy consortium.

IPv6 technology
The DGS-3120 Series supports both IPv4 and IPv6 protocols to meet the ever-increasing demand of larger address space. IPv6 simplifies, streamlines network configuration and also reduces costs of deployment. These switches have been certified with IPv6 ready logo phase 2 from the IPv6 forum, a worldwide IPv6 advocacy consortium. The IPv6 ready logo program provides conformance and interoperability of IPv6 products. MLD snooping enhances efficiency in selective distribution by forwarding multicast data to ports that receive data, rather than flooding all ports in a VLAN. Features such as QoS, ACL (based on IPv6 flow label and traffic class), provide a faster and more efficient service.

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-3120 Series implements the D-Link Green technology, which includes a power saving mode, smart fan, 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 feature allows for the built-in fans to automatically turn on at a certain temperature, providing continuous, reliable and eco-friendly operation of the switch.

Resilience/performance enhancement
The DGS-3120 Series offers superior performance and enhanced network resilience, through the latest 802.1D-2004 RSTP and 802.1Q-2005 MSTP spanning tree protocols. STP allows you to configure the switch with a redundant backup bridge path, so transmission and reception of packets can be guaranteed in event of any fail-over switch on the network. 802.3ad Link Aggregation provides aggregated bandwidth between switches or servers to increase redundancy for higher availability. The switches support 802.1p for Quality of Service (QoS). This standard is a mechanism that classifies realtime traffic into 8 priority levels mapped to 8 queues. Packet classification is based on TOS, DSCP, MAC, IPv4, VLAN ID, TCP/UDP port number, protocol type and user defined packet content, which enables flexible configuration especially for real-time streaming multimedia applications such as Voice over IP (VoIP). The switches also provide a Safeguard Engine for network protection to increase reliability, serviceability and availability. The switches support 802.1p for Quality of Service (QoS).

Traffic control
Network administrators can define throughput levels for each port to allocate its essential bandwidth. Broadcast storm control and flow-based bandwidth control can reduce the level of damage from virus attacks or P2P applications to the network.

Manageability
D-Link's Single IP Management (SIM) simplifies and speeds up management tasks, allowing multiple switches to be configured, monitored and maintained from any workstation running a web browser through one unique IP address. This virtual stack is managed as a single object, having all units maintained by one IP address. The DGS-3120 Series also supports standard-based management protocols such as SNMP, RMON, Telnet, Console, Web-based GUI and SSH/SSL security authentication.
