DES-3528 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 eight
units in a stack, so that the entire stack can act as a single
logical unit with up to 4Gbps of stacking backplane. The
DES-3528 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 four gigabit 10/100/1000BASE-T
ports. Two of these copper Gigabit 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 and 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 spoofi ng. For clients
with Windows

XP SP3, Windows Vista

, or servers
with Windows Server

2008, the 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 DES-3528 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 furthering contamination.
The DES-3528 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 ensuring
network integrity and helping to maintain open network
bandwidth channels.
In addition, the DES-3528 supports 802.1X authentication,
which securely allows 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, in 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.
