DGS-3000-24TCEOL EOS
Tanımlama
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
Network.
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
intrusions.
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.
