The DGS-3120 xStack Series switches 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.
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.
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).
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.
