Nereden Alınır


The DGS-3000 Series is part of the Layer 2 family of D-Link’s managed switch product line that

provides wired Gigabit speed access for metro and campus networks. The two embedded 10G

SFP+ ports on the DGS-3000-26TC guarantee performance during aggregation of numerous

Gigabit connections. The DGS-3000 Series is designed as a 1U rackmount case suitable for

desktops and telecom cabinets. The DGS-3000-10TC is more compact, using a 9-inch case

that comfortably fits in telecom distribution boxes. The smaller dimensions provide better air

flow in limited spaces and also make cable management easier. The embedded alarm port of

DGS-3000-24TC/26TC allows for input of external sensors to detect potential threats such as

open doors or cabinet overheating which then trigger warning events. This makes it ideal for

wide deployment across any metropolitan environment.

Reliable Networking

All of the Ethernet ports of the DGS-3000 Series support 6kV surge/lightning protection. This

feature protects the switch from power surges due to lightning or improper electrical wiring

when the Ethernet cables are exposed in open spaces, such as in old buildings. The switch

also provides an additional power connector for connection to D-Link’s DPS-200 Redundant

Power Supply, or a stable, protected 12VDC backup power source in case of a main power

failure. For Ethernet link fail-over, the DGS-3000 Series supports 802.1D Spanning Tree Protocol

(STP), 802.1w Rapid Spanning Tree Protocol (RSTP), and 802.1s Multiple Spanning Tree Protocol

(MSTP), to allow automatic backup of bridge paths. Using these features, the transmission

and reception of frames can be guaranteed even during a network failure. For mission critical

environments, the switches also support ITU-I G.8032 Ethernet Ring Protection Switching

(ERPS); traffic can be rerouted around the ring within 50 milliseconds, minimizing disruption to

service. D-Link Loopback Detection (LBD) is a protocol-less loop detection function that prevent

loop events from causing congestion in uncontrolled network segments such as unmanaged

switches or customer networks. The DGS-3000 Series also support 802.1AX and 802.3ad Link

Aggregation, which allows grouping of multiple ports in parallel to increase bandwidth and

redundancy for high availability and load sharing in a multi-client environment.

Deliver Triple Play Services

The DGS-3000 Series features full L2 multicast functions, including IGMP/MLD

snooping, fast leave, and filtering. With L2 multicast support, the switches

can handle the increasingly popular IPTV service. Host-based IGMP/MLD

Snooping provide service to multiple IPTV subscribers per physical interface

and ISM VLAN registers multicast streams in a multicast VLAN to save

bandwidth on the network backbone. The ISM VLAN profiles allow users to

bind or replace the channel profiles of subscription ports quickly and easily.

The DGS-3000 Series also supports IGMP authentication, which can prevent

rogue IPTV subscriptions by authenticating Set Top Boxes as well as channel

switching to secure Internet Service Provider (ISP) revenues.

The DGS-3000 Series also supports advanced Quality of Service (QoS)

functions to help ISPs reliably deliver high-quality triple play services. Flexible

packet classification can be based on various header fields or user-defined

packet content to help administrators prioritize network traffic. Two-rate and

single-rate Three Color Marker (trTCM/srTCM) help classify traffic streams

into conforming and nonconforming groups to guarantee the minimum

bandwidth for prioritized packets. The Bandwidth Control feature allows ISPs

to define the upstream/downstream throughput levels for each port with

granularity down to 64 kbps.

Easy Maintenance and Troubleshooting

The DGS-3000 Series features rich Operations, Administration, and

Management (OAM) features to help ISPs reduce the burden of maintenance

and troubleshooting. Cable diagnostics display the status of Ethernet cables

and locate the position of cable errors remotely, helping providers cut onsite

support costs. 802.1ag Connectivity Fault Management (CFM) provides

administrators with a convenient tool to monitor and troubleshoot end-to-end

service networks. This allows service providers to check connectivity, isolate

network issues, and identify the affected customers. D-Link Unidirectional

Link Detection (DULD) helps detect a broken one-way fiber connection,

improving the stability of the fiber infrastructure in a Metropolitan Area


Solid Security with High Availability

The DGS-3000 Series offers various user/device authentication features

including 802.1X, Web-based Access Control (WAC)2 and MAC-based Access

Control (MAC). The clientless WAC2 and MAC functions provide convenience

for IT managers implementing user/device authentication into a network. It

permits administrators to control security without installing client software

on each network device; this is especially important for devices on which the

software cannot be installed. For a greater security level, the DGS-3000 Series

also supports Compound Authentication2, letting IT managers choose

between multiple authentication methods for any single device. Selectable

host-based authentication and authorization provides the option to finely

control access by each device in the network. For advanced applications,

the switches also provide RADIUS and TACACS accounting information

for integration of backend services such as a billing system or advanced

user/device control. In mission critical networks, the DGS-3000 Series

supports strict address and interface binding function via IP-MAC-Port

Binding and ARP Spoofing Prevention to protect the networks from

Man-In-The-Middle or ARP Spoofing attacks.

To maintain a high availability network, the DGS-3000 Series uses D-Link

Safeguard Engine to manage the CPU and ensure that your network stays

up even if it is overloaded by malicious traffic caused by worms and viruses.

The switches also support DHCP Screening to filter out unauthorized DHCP

offerings from rogue DHCP servers or routers. Other security features such

as BPDU Attack Protection, DoS Attack Prevention, and L3 Control Packet

Filtering help to block leaks caused by protocol or behavioral security


IPv6 Ready

The DGS-3000 Series is IPv6 ready and supports various IPv6 functions such

as MLD Snooping, WAC2, IPv6 ACL/QoS, and IMPBv6 to ensure seamless

integration of next generation networks. The DGS-3000 Series also supports a

IPv4/v6 dual stack function that allows the switch to act as a bridge between

IPv4 and IPv6 networks. Finally, all DGS-3000 Series are certified to be

IPv6 ready, which guarantees interoperability for IPv6 environments.
