Product Description:
The DES-3528 xStack® 24-port Managed
Layer 2 switch is ideal for light to
medium voice, video and data
applications and features advanced QoS,
network management and security.
The xStack® DES-3528 by D-Link is a
high-performance, managed, stackable Layer 2 switch
that provides an ideal solution for workgroups and
edge deployments of a network. The D-Link Single IP
Management (SIM) allows administrators to cluster up
a virtual stack of up to 32 DES-3528 dispersed
switches with fewer distance limitations through a
single IP address. The clustering environment spans
buildings, making it perfect for businesses that
require multiple building deployments. The DES-3528
also supports physical stacking of up to 8 units in
a stack, so that the entire stack can act as a
single logical unit with up to 4Gbps of stacking
backplane. 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 DES-3528 provides a non-blocking switching
solution for 10/100 Fast Ethernet connections. The
DES-3528 supports 24 10/100Mbps ports, with 4
gigabit 10/100/1000BASE-T ports. Two of these
gigabit copper ports are disabled when the two
1000BASE-X SFP are used, also known as dual
personality or combo ports. The DES-3528 has a
non-blocking bandwidth of 12.8Gbps; the xStack
switch has a redundant power option for mission
critical applications.
Advanced Network Security
For edge network security, the DES-3528 supports
DHCP server screening, client filtering, and
IP-MAC-Port Binding to prevent security breaches
such as rogue DHCP server, man-in-the-middle attacks
and IP spoofing. For clients with XP SP3, Vista, or
servers with Microsoft’s Server 2008, DES-3528 works
in conjunction with Microsoft’s Network Access
Protection (NAP) as part of an ecosystem that
enforces compliance with network health policies.
The xStack switch 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 a virus-infested
client or server from gaining access and further
contamination.
The xStack switch also supports loopback
detection, which detects a loop in the network even
though the end device causing the loop is without
spanning tree. When the switch detects a loop is in
the connected node, the DES-3528 shuts down the port
with the loop so that the entire system will
continue to function normally. This feature can also
be VLAN based.
The DES-3528 incorporates advanced mechanisms to
detect an attack against the switch’s central
processing unit and to take corrective action on the
attacking interface. When a Denial of Service attack
is waged against the xStack switch, 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-3528 supports 802.1x
authentication, which securly 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
network. Web-based authentication option is
available for those clients who may not have the
802.1x supplicant, while MAC-based authentication
can make the authentication process automatically,
authenticated by the 802.1x server based on the
client’s MAC address. 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.
IP Clustering Stackable
The xStack DES-3528 provides D-Link Single IP
Management Technology (SIM), allowing a set of
switches to be managed by a single IP, regardless of
geographical locations. Traffic running among units
in this virtual stack is through the full-duplex
Gigabit interfaces and your usual network wires,
doing away with the costly and cumbersome stacking
cables. Without any stacking cable, cable distance
barrier and physical stacking limitations, your
stack can comprise 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. With Tree View, you can obtain and
overview of the members of the stack and a network
topology showing the locations of the units and
their link information. This provides simple yet
powerful web-based management without expensive SNMP
network management software. You can 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 businesses, having voice, data and video
on the same network is common practice. This
challenge is met by the DES-3528, which supports
802.1p with 8 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 is always clear and jitter free.
Video traffic can also be assigned with the same
priority. In addition, the switch provides IGMP
Snooping or MLD snooping, which allows the
forwarding of multicast packets such as streaming
audio and video, without increasing network
broadcast congestion. By snooping IGMP registration
information within a frame, a list of workstations
in the multicast group is created. This list then
allows the switch to intelligently forward packets
to only the appropriate member workstations. In
conjunction with the 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 DES-3528 provides advanced
features for easy video streaming management. For
example, this xStack family 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
that pre-configures channels for each subscriber on
a port level to prevent unauthorized multicast join.
DES-3528 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.
Ease of Management
The DES-3528 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 and IEEE 802.1d/w/s spanning tree,
User interface includes intuitive web-based browser
graphic interface or industry-standard CLI, either
administration traffic can be protected thru SSL or
SSH encryptions.
