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 it an ideal access layer solution. The DGS-3120 Series provides 8/24/48 10/100/1000Mbps Gigabit ports, 4/8 combo SFP and embedded with two CX4 interfaces for high speed switch stacking. Each 10/100/1000 Mbps port of DGS-3120-24PC/48PC supports 802.3af and 802.3at Power over Ethernet standard to connect with PoE devices such as high speed 802.11n Access Points, IP phones and cameras. The DGS-3120-24SC provides 16 dedicated SFP ports with 8 combo Gigabit Ethernet copper/ SFP ports and 2 CX4 ports for high-speed switch stacking. This device has high port density of SFP interfaces, which is ideal for WAN aggregation. The dedicated CX4 stacking ports provide up to 40G bidirectional bandwidth which makes the DGS-3120 Series suitable as a backbone solution for SMBs. The integrated and comprehensive D-Link End-to-End Security solution (E2ES) on DGS-3120 Series extends the network security coverage from core to the edge. D-Link Safeguard Engine protects DGS-3120 Series from the threat of worms/virus increasing the overall reliability, serviceability and availability. Furthermore, D-Link Green Technology decreases energy costs by reducing power consumption, without compromising on performance. The DGS-3120 Series supports Smart Fan feature which has heat sensors and a fan that maintains the temperature of the device for optimum performance. To minimize noise reduction, the default fan speed is set to low. These switches are ideal for deployment in offices or environments that require silence.

End-to-End Security (E2ES)
D-Link extends intelligence by combining Endpoint, Joint and Gateway Security to provide a complete End-to-End Security Solution. This integrated security solution combines switches, firewalls and Wireless LAN with unified threat management for easy security management for the edge, to the core enterprise network. The DGS-3120 Switch Series provides a rich list of Endpoint Security features to add confidence and assurance to your network. It offers comprehensive protection, including user authentication, VLAN authorization, traf?c control and segmentation, node address control, and attack mitigation. The switches also support 802.1X Port-based/Hostbased Access Control, Guest VLAN, and RADIUS and TACAS+ for strict access control over the network along with Web-based Access Control (WAC) and MAC-based Access Control (MAC) for easy deployment. User-defined Access Control List (ACL) secures your internal IT network against viruses and enhances switch performance. The IP-MAC-Port Binding feature allows administrators to bind a source IP address with an associated MAC and also lets the administrator define the port number to enhance user access control. The switches also support DHCP Server Screening, a feature that denies access to rogue DHCP servers. Enable this function to filter out all the DHCP Server packets from a specific port. Other security features like port security and traffic segmentation provide granular control to businesses and enhance network security. D-Link’s Joint Security solution provides admission control and real-time defense through Microsoft’s NAP (Network Access Protection) and D-Link’s ZoneDefense respectively. The ZoneDefense technology allows customers to integrate their switches with D-Link’s NetDefend firewall, for full coverage and proactive security architecture. NAP is a policy enforcement technology built into Windows 7®, Vista and XP SP3 that allows customers to protect network assets from unhealthy computers by enforcing compliance with network health policies.

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. For IPv6 Management, the switches support Web, telnet and SNMP over IPv6.

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 ecofriendly 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.

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.

The switches are also equipped with an SD Card reader, allowing the user to boot images and upload configuration files directly from an SD Card. Furthermore, syslog files can also be conveniently saved to a card.
