Overview
Standard and Enhanced Images
The DGS-3120 Series offer flexibility with 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.
Enhanced Network Reliability
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 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 prioritizes CPU interested packets to prevent malicious traffic
from interrupting normal network flows, and to protect switch
operation.
Identify Driven Netwrok 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 and 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.
Proactive, Effective Network Management
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, 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 affected by network
issues.
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 Neighbour
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 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.
Manageability
D-Links
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.
