The DGS-3120 Series xStack switches are enhanced L2+ Gigabit switches designed to connect
end-users in a secure campus or enterprise network. These switches support physical stacking
multicast, and enhanced security, making them an ideal Gigabit access layer solution. The
DGS-3120-24TC/48TC provides 20 or 44 10/100/1000 Mbps Gigabit Ethernet ports, and 4
combo 1000BASE-T/SFP Gigabit Ethernet ports. The DGS-3120-24PC/48PC provides 24 or 48
10/100/1000 Mbps PoE Gigabit Ethernet ports and 4 combo 1000BASE-T/SFP Gigabit Ethernet
ports. The DGS-3120-24SC provides 16 SFP Gigabit Ethernet ports and 8 combo 1000BASE-T/
SFP Gigabit ports. Each 10/100/1000 Mbps port on the DGS-3120-24PC/48PC supports the
802.3af and 802.3at Power over Ethernet standards. The default power budget for these
models is 370 watts and can be expanded to 760 watts with the DPS-700 RPS. The switches are
also equipped with an SD Card slot, allowing the user to boot images and upload con guration
les directly from an SD Card as well as conveniently save syslog les onto the SD Card.
Standard and Enhanced Images
The DGS-3120 Series has support for two di erent software images - the Standard Image (SI)
and Enhanced Image (EI) The Standard Image provides sophisticated features for campus or
enterprise usage. It includes advanced Quality of Service (QoS), tra c shaping, L2 multicasting,
robust security features, and IPv6 features which are suitable for next-generation IPv6 networks
or triple play applications over Metro Ethernet. The Enhanced Image supports ERPS, Double
VLAN (Q-in-Q), Ethernet OAM, Static Route, IMPB, and sFlow.

Enhanced Network Reliability
The DGS-3120 Series targets enterprises, campuses, and customers who require
a high level of network security and maximum uptime. All the models in the
DGS-3120 Series support an external redundant power supply so that continued
operation can be assured. They also include other features, such as 802.1D
Spanning Tree (STP), 802.1w Rapid Spanning Tree (RSTP), and 802.1s Multiple
Spanning Tree (MSTP), Loopback Detection (LBD), and Broadcast Storm Control,
that enhances network resilience. G.8032 Ethernet Ring Protection Switching

If the worst should happen to your network you need the very best
support and fast. Downtime costs your business money. D-Link
Assist maximises your uptime by solving technical problems
quickly and e ectively. Our highly trained technicians are on
standby around the clock, ensuring that award-winning support
is only a phone call away.
Comprehensive Security
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
1
IP-MAC-Port Binding (IMPB)
feature allows administrators to bind a source IP address with an associated
MAC and also de ne 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 identi es and prioritizes “CPU interested” packets
to prevent malicious tra c from interrupting normal network ows, and to
protect switch operation.
with DHCP Snooping. The IP-MAC-Port Binding
Identity Driven Network Policies
The DGS-3120 Series supports authentication mechanisms such as 802.1X, Web-
based Access Control (WAC), and MAC-based Access Control (MAC) for strict
access control and easy deployment. After authentication, individual policies
such as VLAN membership, QoS policies, and ACL rules can be assigned to each
host. In addition, the switch also supports Microsoft® NAP (Network Access
Protection). NAP is a policy enforcement technology that allows customers to
protect network assets from compromised computers by enforcing compliance
with network health policies.
Traffi c Management for Triple Play
The DGS-3120 Series implements a rich set of multilayer QoS/CoS features to
ensure that critical network services such as VoIP, video conferencing, IPTV,
and IP surveillance are given high priority. Tra c Shaping features guarantee
bandwidth for these services when the network is busy. L2 Multicast support
enables the DGS-3120 to handle growing IPTV applications. Host-based IGMP/
MLD Snooping allows multiple multicast subscribers per physical interface and
ISM VLAN to send multicast streams in a multicast VLAN to save bandwidth
and to provide better security to the backbone network. The ISM VLAN pro les
allow users to bind/replace the pre-de ned multicast registration information
to subscriber ports quickly and easily.

DGS-3120 Series xStack L2+ Managed Gigabit Switches
Proactive, Eective Network Management
To uphold enterprise customers’ Service Level Agreements (SLA), service providers must reduce their Mean Time to Repair (MTTR) and increase service availability.
Ethernet OAM features address these challenges and enable service providers to oer 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 aected by network issues.
IPv6 Technology
The DGS-3120 Series is fully compliant with future IPv6 networks. It supports remote IPv6 manageability from telnet, HTTP, or SNMP. To create secure IPv6 networks,
the DGS-3120 Series uses IPv6 ACL, DHCPv6 Snooping, and Neighbor Discovery (ND) Snooping functions to protect the network from illegal IPv6 clients. The DGS-
3120 Series has been certied with IPv6 Ready Logo Phase 2 from the IPv6 forum, a worldwide IPv6 advocacy consortium. The IPv6 Ready Logo Program ensures
the conformance and interoperability of IPv6 products.
Green Technology
D-Link is striving to take the lead in developing innovative and power-saving technology that does not sacrice operational performance or functionality. The
DGS-3120 Series implements the D-Link Green Technology, which includes a power saving mode, Smart Fan, reduced heat, and cable length detection. The power-
saving feature automatically powers down ports that have no link or link partner. The Smart Fan feature enables the built-in fans to automatically turn on at a
certain temperature, providing continuous, reliable, and ecofriendly operation of the switch. Energy Ecient Ethernet (EEE) standard is also supported, which
helps to reduce the operating cost of the DGS-3120 Series.
Manageability
D-Link’s Single IP Management (SIM) simplies and speeds up management tasks, allowing multiple switches to be congured, 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.
