Product Description:
The D-Link xStack™ DES-3526 is a
high-performance, managed, stackable
Layer 2 switch that provides an ideal
solution for workgroups and departments.
D-Link Single IP Management (SIM) allows
to cluster up a virtual stack of up to
32 DES-3526 switches dispersed switches
with fewer distance limitation through a
single IP address. The clustering
environment spans buildings, making it
perfect for businesses that require
multiple building deployment. The xStack
switch also provides comprehensive
security for edge access such as Access
Control List, DHCP server screening, and
DoS attack prevention.
Non-Blocking Switching
The D-Link xStack DES-3526 provides non-blocking
switching solution for a 10/100 fast Ethernet
connection. The DES-3526 supports 24 10/100Mbps
ports, with 2 gigabit 10/100/1000BASE-T ports. These
gigabit copper ports will be disabled if the two
1000BASE-X SFP are used - known as dual personality
or combo ports. The DES-3526 has a non-blocking
bandwidth of 8.8Gbps and has a redundant power
option for mission critical apps.
D-Link Safeguard Engine and Security
The DES-3526 incorporates advanced mechanisms to
detect an attack against the central processing unit
of the switch and to take corrective action on the
attacking interface. When a Denial of Service (DoS)
attack is waged against the xStack switches, the
D-Link Safeguard Engine detects the threat and
prevents overload of the central processor thus
insuring network integrity and helping to maintain
open network bandwidth channels.
In addition, the DES-3526 supports 802.1x
authentication, which is a secure means to allow
users to log onto your network. When used in
conjunction with a RADIUS server, 802.1x requires
each user workstation attached to the xStack
switches to provide a username and password before
gaining access to the local area network. Other
security features include access control list, which
an administrator can restrict the access of a
network through a variety of means including MAC
address, IP, UDP/TCP, and even VLAN ID.
For edge network security, the DES-3526 supports
features such as DHCP server screening, client
filtering, and IP-MAC-Port Binding to prevent
security breaches such as rogue DHCP server,
man-in-the-middle attacks or IP spoofing. For
clients with Windows® XP SP3, Windows Vista®, or
servers with Microsoft® Windows Server 2008, the
DES-3526 works in conjunction with the Microsoft®
Network Access Protection (NAP) as part of an
ecosystem that enforces compliance with network
health policies. xStack switches will grant network
host access only if it complies with IT security
policies such as up-to-date anti-virus signatures
and operating system patches. This prevents an
infected client or server from gaining access and
further contaminating the network.
Ease of Management
DES-3526 supports SNMP v1/2/3 so traps can be set on
abnormal events and information can be polled to
maximize the productivity of the network. Other
standard management features are also supported
including RMON, intuitive Web-based graphic
interface, and industry-standard Command Line
Interface (CLI).
IP Clustering Stackable
The xStack DES-3526 includes D-Link Single IP
Management Technology (SIM), which allows a set of
switches to be managed by a single IP, regardless of
geographical locations. Traffic running across units
in this virtual stack utilize full-duplex interfaces
and network wires, eliminating costly and cumbersome
cables. Without any stacking cables, cable distance
barriers, and physical stacking limitations, your
stack can be comprised of units that are located
anywhere on the network, minimizing the impact of
any single point of failure. Furthermore, multiple
xStack switches can be configured, monitored, and
maintained from any workstation running a Web
browser through one unique IP address. The stack is
managed as a single object, with all units
identified by a single IP address. You can see a
Tree View of the members of the stack and a network
topology showing the locations of the units and
their link information. This simple yet powerful
Web-based management eliminates the need for you to
install expensive SNMP network management software.
Add up to 32 switches per stack, not limited to any
specific D-Link models. With embedded SIM, you can
expand your Ethernet stack to include L3 core
Gigabit and chassis based switches to accommodate
your network growth.
Voice and Video Applications
For today’s business, having voice, data and video
on the same network is common practice. This
challenge is met by the D-Link DES-3526, which
supports 802.1p with 4 queues. The administrator can
designate the priority of the traffic based on a
variety of means including IP or MAC address, so
that voice data always is always clear and jitter
free. Video traffic can also be assigned with the
same priority. In addition, the D-Link DES-3526
provides IGMP Snooping, which allows the forwarding
of multicast packets such as streaming audio, video,
without increasing network broadcast congestion. By
snooping IGMP registration information within a
frame, a list of workstations who have joined the
multicast group is created. This list then allows
the switch to intelligently forward packets to only
the appropriate member workstations. In conjunction
with 802.1Q VLANs, Quality of Service and security
can be achieved on a network infused with data
traffic.
For other multimedia-on-demand applications, such
as IPTV deployments, the xStack DES-3526 provides
advanced features for easy video streaming
management. For example, this xStack supports per
port multicast stream control, which allows a
service provider to assign limited multicast
addresses per port. This means it can act as a
security control pre-configured channels for each
subscriber on a port level to prevent unauthorized
multicast access. DES-3526 also supports IGMP
multicast VLAN, which eliminates duplicate multicast
traffic being sent to clients in different VLANs and
thus removing bottlenecks in the uplink port.
