The DGS-3120 xStack Series are enhanced L2 stackable access 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-3120-24TC and DGS-3120-48TC provide
20 or 44 10/100/1000 Mbps Gigabit Ethernet ports and 4 combo 1000BASE-T/
SFP Gigabit Ethernet ports. The DGS-3120-24PC and DGS-3120-48PC provide 20
or 44 10/100/1000 Mbps PoE Gigabit Ethernet ports and 4 combo 1000BASE-T/
SFP Gigabit Ethernet ports. Each 10/100/1000 Mbps port of DGS-3120-24PC/48PC
supports IEEE 802.3af and IEEE 802.3at Power over Ethernet standard. The default
power budget is 370 Watts and can be expanded to 740 Watts with the DPS-700
RPS. The switches are also equipped with an SD Card slot, 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.
Standard and Enhanced Software Images
The DGS-3120 Series supports two different software images - Standard Image (SI)
and Enhanced Image (EI). The Standard Image provides sophisticated features for
campus, or enterprise. It includes 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.
All DGS-3120 models are shipped with the Standard Image. A separately orderable
license key may also be ordered which activates the Enhanced Image.
DGS-3120 Series
xStack L2 Managed Stackable Gigabit Switches
Enhanced Network Reliability
Proactive, Effective Network Management
The DGS-3120 Series targets enterprise/campus and customers
who 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 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
enhance network resilience. The G.8032 Ethernet Ring Protection
Switching (ERPS) function minimizes the recovery time to 50 ms2.
For load sharing and redundancy backup in switch cascading/server
attachment configuration, the DGS-3120 Series provides dynamic
802.3ad Link Aggregation Port Trunking.
To uphold enterprise customers’ 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,
IEEE 802.1ag, 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.
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 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.
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 unhealthy computers by enforcing compliance
with network health policies.
Traffic Management for Triple Play
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. Host-based IGMP/MLD
Snooping allows multiple multicast subscribers per physical interface,
ISM VLAN sends multicast streams in a multicast VLAN to save
bandwidth and to provide better security to the backbone network.
The ISM VLAN profiles allow users to bind/replace the pre-defined
multicast registration information to subscriber ports quickly and
easily.
IPv6 Technology
The DGS-3120 Series is fully compliant with the 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 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.
D-Link Green Technology
D-Link is striving to take the lead in developing innovative and powersaving 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 adjust
their speed at a certain temperature, providing continuous, reliable and
eco-friendly operation of the switch.
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 DGS3120 Series also supports standard-based management protocols such
as SNMP, RMON, Telnet, Console, Web-based GUI and SSH/SSL security
authentication.
Lifetime Warranty and NBD Replacement
D-Link offers a Lifetime Warranty and Next Business Day (NBD)
hardware replacement on the DGS-3120 Series of xStack L2 Managed
Stackable Gigabit Switches to further its commitment to product
quality and long-term customer confidence.
