DGS-3100 Family
DGS-3100-24 DGS-3100-24P
Managed 24/48-port Gigabit Stackable L2 Switches
with 4 Combo SFP Slots
Overview
The D-Link DGS-3100 family of switches provides
®
entry-level, Layer 2 managed performance at gigabit
speeds. Each model provides 10/100/1000Base-T
auto-sensing ports, in both 24 and 48-port options.
Power over Ethernet (PoE) models are available with
24 or 48-ports, supplying up to 15.4 Watts of power to
802.3af-compliant devices, such as high-demand 802.11n
Access Points, IP Phones and Cameras. Every model
also comes equipped with 4 combo SFP ports, giving
you greater network flexibility, and 2 HDMI ports for
high-speed switch stacking. Up to 6 switches can be
stacked under a single IP Address, providing up to
288Gbps total bandwidth for the ideal small-to-medium
business backbone solution.
Management and security features round out these robust
switches. An advanced Access Control List (ACL) and the
D-Link Safeguard Engine provide security coverage from
core to edge and protect against worms and viruses and
Denial-of-Service attacks. Quality of Service (QoS) and
IGMP Snooping move your data smoother and faster. And
easy-to-use administration interfaces, along with SNMP
and RMON, mean faster setup and configuration with less
downtime.
High-Speed Switch Stacking
Each switch in the DGS-3100 family includes two HDMI
stacking ports to provide up to 20Gbps in stacking backplane,
or 10Gbps on each port. That's 5 times the speed of a gigabit
port! These switches are also hot-swappable and can be
replaced or removed without affecting the network. With
cross stack port mirroring and port trunking to facilitate
network administration, your network data will move more
efficiently than ever before.
D-Link Safeguard Engine ™ and Security
The DGS-3100 family incorporates advanced mechanisms
to detect attacks and take corrective action on the attacking
interface. When a Denial of Service (DoS) attack is waged,
DGS-3100-48 DGS-3100-48P
the D-Link Safeguard Engine detects the threat and prevents
overload of the central processor to insure network integrity
and help maintain open network bandwidth channels.
In addition, the switches support 802.1x authentication,
which is used in conjunction with a RADIUS server to
require a username and password before access to the
network is allowed. Granular management can even be
based on the MAC Address, for those clients that are not
802.1x-compliant. Other security features include an access
control list, which restricts network access through such
means as a MAC address, IP, UDP/TCP, and even VLAN ID.
Future firmware downloads will also include time-based
ACLs, especially useful for educational infrastructures that
provide time-limited access.
Advanced Enterprise Features
With voice, data and video often on the same network,
today's businesses often need to prioritize network traffic.
The DGS-3100 family meets this challenge with a variety of
advanced features, beginning with 4 queue 802.1p QoS. This
feature allows the administrator to prioritize traffic based on
IP or MAC address, for voice data that is always clear and
jitter free. Video traffic can also be assigned as a priority.
The switches also utilize IGMP Snooping to analyze data
packets and forward them through only where appropriate.
This means that multicast packets, such as streaming audio
and video or other bandwidth hogs, get through without
creating extra network congestion. This smart packet
management also reduces the workload of other devices
further down the line, making your entire network function
more efficiently. With these advanced features used in
conjunction with 802.1Q VLANs, Quality of Service and
greater security can be achieved on your network.
The DGS-3100 family also supports 802.1Q VLANs, for
greater QoS and security on the most data-laden networks.
IPv6 traffic will move even more efficiently with MLD
Snooping. DGS-3100 also supports IEEE 802.1AB LLDP, so
administrators can easily find other devices attach to the
network and manage them.
