The DGS-3000 Series Gigabit L2 Managed Switches are part of the Layer 2 family of D-Link’s
managed switch product line that provides wired Gigabit speeds for Metro Ethernet and
campus networks. They feature a variety of ports, including 10/100/1000BASE-T RJ-45 ports, 1G
SFP ports, and 10G SFP+ ports for increased network bandwidth. Surge protection, advanced
Layer 2 functions, and a suite of security and management tools make the DGS-3000 Series
Gigabit L2 Managed Switches ideal for Metro Ethernet and campus applications.
Multi-Gigabit Performance
The DGS-3000 Series Gigabit L2 Managed Switches come with a variety of port types, including
1 G RJ-45 ports, 1 G SFP ports, and 10G SFP+ ports, with all models oering a minimum of at
least 2 1 G SFP ports. The DGS-3000-28X and DGS-3000-52X oer 4 10G SFP+ ports for improved
bandwidth and fault tolerance. The DGS-3000-28LP and DGS-3000-28XMP switches feature
Power over Ethernet (PoE), allowing compatible devices to be installed in remote locations
without immediate access to power outlets.
Ecient and Resilient Networking
The DGS-3000 Series supports up to 6 kV surge protection on all Ethernet ports, protecting
the switch from power surges due to lightning strikes or faulty electrical cabling. The
DGS-3000 Series supports ITU-T G.8032 Ethernet Ring Protection Switching (ERPS), which
allows 50-millisecond failover in the event of a failure of one of the rings, minimising service
disruption. The switches also support IEEE 802.1AX and 802.3ad Link Aggregation, which
allows grouping of multiple ports to provide redundancy and load balancing in mission-critical
environments.

Quality of Service
The DGS-3000 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. Flexible packet classication can
be based on various header elds or user-dened packet content to help
administrators prioritise network trac. Trac Shaping features guarantee
bandwidth for these critical services when the network is busy. Multilayer
QoS/CoS features let IT managers arrange network resources more eciently
in enterprise environments.
Identity-driven Network Policies
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 eectively. Our highly trained technicians are on
standby around the clock, ensuring that award-winning support
is only a phone call away.
The DGS-3000 Series supports authentication mechanisms such as 802.1X
port-based Access Control, Web-based Access Control (WAC), and MAC-based
Access Control (MAC) for strict access control to network resources. After
authentication, individual policies such as VLAN membership, QoS policies,
and ACL rules can be assigned to each host. Additionally, the switches support
Microsoft® NAP (Network Access Protection), which allows network assets to
be protected from compromised computers by enforcing compliance with
network health policies.
Manageability
D-Link 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 and with network connectivity.
All switches can be managed as a virtual stack, allowing physically separate
switches to be managed using a single IP address. The DGS-3000 Series also
supports management tools such as a Web UI, SSH, Telnet, and console, and
standards-based protocols such as SNMP, RMON, and SSL.
Security & Authentication
The DGS-3000 Series oers user and device authentication, including host-
based authentication and authorization, which provide the option to nely
control network access for each device on the network. Advanced features
such as RADIUS accounting allow the switches to be integrated with back-
end systems for billing or advanced access control. The DGS-3000 Series also
supports address and interface binding features such as IP-MAC-Port Binding
and ARP Spoong Prevention to protect against Man-in-the-Middle or ARP
Spoong attacks.
