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, and DXS/DWS-3227,
providing extraordinary flexibility. It
provides 24 built-in copper Gigabit
ports, including 4 combo SFP ports for
easy, flexible connection to fiber-based
Gigabit media. The DWS-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 1 fixed 10GbE XFP port for a
total switching capacity of up to
120Gbps. In addition, the DWS-3227 also
supports IP static routing, 4000 VLANs,
up to 64 trunk groups, and is
‘wireless-ready’, making the DWS-3227
the most feature rich, high capacity
switching solution in its class by far.
The DWS-3227 comes standard with a 10
client AP license upgradeable to 50, and
is capable of supporting 50 APs per
switch /stack with up to 600 WLAN
clients.
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 DWS-3227
is capable of meeting this demand and more. With a
simple optional firmware upgrade, the DWS-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 demand mobility and
seamless integration such as PDA and 3G/VOIP mobile
phones. With an optional software upgrade, the
DWS-3227 becomes a wireless switch providing secure,
seamless roaming between access points ensuring
clear, 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 3200 Series of xStack
switches. Switches built with DNA are easily
stackable with little or no system downtime for
expansion. For example, the DWS-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 10 GbE
interface or using a 1000Base-X port to connect
between wiring closets. The DWS-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 DWS-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 allows 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 DWS-3227 is equipped to handle many of today’s
emerging security vulnerabilities previously
delegated to only standalone 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 network. Furthermore, the
DWS-3227 protects against attacks towards the CPU
itself and improves utilization to meet existing
network demands to maximize device responsiveness to
user configuration activities.
High Availability
The DWS-3227 supports “Shortest-Path” switching,
which improves resiliency, uptime and network
efficiency. It also supports an optional Redundant
Power Supply (DPS-500). It includes support for
802.3ad Link Aggregation, and 802.1w Rapid Spanning
Tree for increased network reliability and
availability.
Network Management
The DWS-3227 features a variety of network
management options: Console CLI, Telnet, Web GUI,
SNMPv1/v2/v3, and RMON. It also supports a variety
of advanced traffic management options including:
Layer 3 Static Routing, Bandwidth Control, Broadcast
Storm Control, Private VLANs, and support for IGMP
Snooping. D-Link’s exclusive DNA stacking technology
is also supported, which allows up to 16 D-Link
DWS-3227 switches to be stacked together* and
managed as a single unit, regardless of its physical
environmen.
Advanced QoS
The DWS-3227 provides a robust and consistent set of
QoS/CoS, supporting 8 priority queues for 802.1p/ToS/DiffServ,
with classification and marking based on MAC SA/DA,
IP SA/DA, and/or TCP/UDP. It also provides extensive
support for GARP/GVRP, 802.1q, and port-based VLANs
for up to 4000 groups per device.
Wireless AP License
The xStack DWS-3227 switch provides secure, seamless
roaming between access points ensuring clear,
uninterrupted data and voice communication
throughout your wireless network infrastructure. The
DWS-3227 supports an optional 10, 25, or 50 client
AP license and is capable of supporting up to 50 APs
per switch /stack with up to 600 WLAN clients.
Centralized Management
The xStack DWS-3227 is capable of centralized
management of compatible wireless access points. No
longer will each individual access point need to be
configured independently. Now your entire wireless
network can be managed through a single interface.
The xStack DWS-3227 includes support for automatic
discovery APs with real-time monitoring, providing
visibility into utilization and performance of WLAN
users and devices.
Wireless Security
The D-Link xStack DWS-3227 provides Enhanced
Wireless Security features to ensure your data is
protected from hackers. Support for WEP, WPA™ and
WPA2™ Encryption guarantees the privacy of your
network data. Rogue AP detection and containment
ensure that only the APs you install are able to
function on your network. AP detection allows
identification of APs into “known” and “rogue”
classifications. The switch uses the APs to
continuously scan radio channels in an attempt to
identify transmissions of unauthorized WLAN nodes
facilitating notification, and/or jamming of the
rogue signals.
Seamless Wireless Roaming
When a user roams between APs connected to different
broadcast domains, the user’s IP address is no
longer valid after the move to the new AP. This
means the user’s device (laptop, PDA, VoIP phone)
will need to change its IP address thus breaking the
active session. With “always connected” devices such
as VoIP phones and PDAs, this can create a huge
problem. The need for a solution to provide seamless
roaming between APs on different subnets becomes
essential to maintaining active sessions and VoIP
calls.
The D-Link DWS-3227 addresses this problem by
bringing AP configurations and support directly into
the switch itself. This allows the user to move
between access points with seamless mobility. To the
user’s PDA or VoIP phone, the move appears as if it
were between APs on a single broadcast domain. This
means the user’s device will retain its VLAN
membership and IP address guaranteeing uninterrupted
communication.
Inter-Switch Roaming
The xStack DWS-3227 supports roaming of wireless
stations between access points attached to different
switches. The seamless inter-switch roaming
procedure allows a station’s VLAN membership (IP
subnet) and QoS parameters to be retained when
roaming between APs connected to multiple switches
throughout the network. Inter-Switch roaming is an
extremely beneficial feature when creating a large
WLAN environment such as a campus or multi-floor
office. Inter-Switch roaming allows the user
complete freedom to roam between switches located in
different buildings or on different floors without
disconnection or need for re-authentication.
Supported Access Points
Designed for the xStack 3200 series line of wireless
switches, the DWL-2130AP, DWL-2230AP, DWL-7130AP,
and DWL-7230AP wireless thin access points offer a
flexible solution for integration with the xStack
3200 series wireless switch series. With distinct
models for every topology, these access points offer
a variety of features ranging from support for

Ethernet (PoE). When used in conjunction with the
xStack DXS/DWS-3227, DXS/DWS-3227P, and DXS/DWS-3250,
these thin access points unlock the power of
wireless switching and facilitate advanced features
such as centralized AP management, seamless Layer 3
roaming, and rogue AP detection and jamming.
