Overview
D-Link’s xStack 3200 Series switches are designed to
provide effortless wireless technology convergence with
traditional Layer 2 data access switching, emphasizing
on security, performance, and resiliency. Featuring
the latest stacking technology from D-Link, the
xStack DXS-3227 can stack up to 16 units*, providing
up to 400 Gigabit ports. It can stack with other D-Link
switches such as the (DXS/DWS-3250, DXS/DWS-3227P),
advocating extraordinary flexibility. It provides 24 built-in
copper Gigabit ports, including four combo SFP ports
for easy, flexible connection to fiber-based Gigabit
media. The DXS-3227 is also equipped with 2 module
slots that support 10 Gigabit Ethernet for both copper
CX-4 and fiber XFP connections, as well as one fixed
10GbE XFP port for a total switching capacity of up to
108Gbps. In addition, the DXS-3227 also supports IP
static routing, 4000 VLANs, up to 64 trunk groups, and is
‘wireless-ready’, making the DXS-3227 the most feature
rich, high capacity switching solution in its class by far.
Unified Wired/Wireless Ready
In a mixed network of wired and wireless environments,
predictable coverage and security become paramount.
The need for a switching solution capable of addressing
these needs in both the wired and wireless environment
becomes key. The DXS-3227 is capable of meeting this
demand and more. With a simple optional firmware
upgrade, the DXS-3227 transforms from a standard Layer
2 switch into an integrated wired and wireless switching
solution capable of providing powerful wireless security,
easy deployment, the ability to detect rogue access
points, and centralized management for all compatible
WLAN components. Centralized management is crucial
for wireless technologies deployed in real-time inventory,
data mining, and an array of personal electronics that
demands mobility and seamless integration such as
PDA and 3G/VOIP mobile phones. With an optional
software upgrade, the DXS-3227 provides secure,
seamless roaming between access points, ensuring
uninterrupted data and voice communication
throughout your wireless network infrastructure.
DNA Stacking Architecture
Distributed Network Architecture (DNA) is a combination
of hardware and software that is embedded in D-Link’s
latest DXS-3200 series of xStack switches. Switches built
with DNA are easily stackable with little or no system
downtime for expansion. For example, the DXS-3200
Series switches are self-healing by quickly discovering
failures in the stack and re-routing traffic to automatically
avoid the failed device and discover the new topology.
The flexibility of DNA lets network designers choose the
right topology for connecting their devices whether it be
through a 10GbE interface or using a 1000Base-X port to
connect between wiring closets. The DXS-3200 series
switches can be used in a number of topologies such as
ring or chain stacking. When changes are made to the
stack, DNA automatically discovers the new topology
and reconfigures the system to accommodate the
changes. In the unlikely event of equipment failure, the
switches rapidly reconfigure the stack to avoid the failed
switch, resulting in extremely fast failover times and little
to no downtime. In addition, the DXS-3200 Series allows
the network administrator to maintain transparency of
system features such as Port Mirroring, VLANs, and
link aggregation across the stack. Unlike other stacking
solutions, this feature will allow an administrator to
add and remove ports from VLANs without having to
configure the VLAN on each switch and without the
added hassle of creating VLAN trunks between devices.
This also allows, through the use of port mirroring, the
ability to monitor any port throughout the stack without
having to be physically connected to the same device.
This flexibility allows for better troubleshooting, faster
configuration, and a lower risk of configuration errors.
Comprehensive Security
The DXS-3227 is equipped to handle many of today’s
emerging security vulnerabilities previously delegated to
only stand-alone firewalls. It incorporates built in ACLs
for searching out and filtering such threats as: Denial of
Service attacks, Trojan Horses, Worms, and more. Other
access rules can also be set up to prevent network,
and 802.1x authentication login. In addition, port-based
security can also be set up to protect the integrity of the
