For DGS-3120-24PC/48PC models only.
The DGS-3120 xStack Series are enhanced
L2 access stackable switches designed to
connect end-users in a secure business
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
of DGS-3120-24PC/48PC supports 802.3af
and 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 Images
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
businesses. 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.

Enhanced Network Reliability
The DGS-3120 Series targets businesses
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
minimises the recovery time to 50 ms. For load
sharing and redundancy backup in switch
cascading/server attachment configuration,
the DGS-3120 Series provides dynamic
802.3ad Link Aggregation Port Trunking.

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 prioritises
“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.
