DWS-3227P Layer 2+ Stackable Gigabit Wireless Unified Switch
xStack Managed 24-Port Stackable PoE Gigabit Wireless
Switch, 10AP License
Comprehensive Security
The DWS-3227P 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. With the D-Link
Safeguard Engine, the DWS-3227P protects against
attacks towards the CPU itself and improves utilization
to meet existing network demands to maximize device
responsiveness to user configuration activities.
In addition, well-known port numbers for allowed
applications can be pre-programmed, which will allow
these applications faster service and reduce the load
on the CPU.
High Availability
The DWS-3227P supports “Shortest-Path” switching,
which improves resiliency, uptime and network efficiency.
It also supports an optional Redundant Power Supply. It
includes support for IEEE 802.3ad Link Aggregation,
and 802.1w Rapid Spanning Tree for increased network
reliability and availability.
Network Management
The DWS-3227P 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 8 D-Link DWS-3227P
switches to be stacked together and managed as a single
unit, regardless of its physical environment.
Advanced QoS
The DWS-3227P provides a robust and consistent set of
QoS/CoS, supporting 8 priority queues for IEEE 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, IEEE 802.1q, and
port-based VLANs for up to 4000 groups per device.
Power over Ethernet IEEE 802.3af
Wherever the location—factory, warehouse, campus,
small office, or enterprise facility—the challenge and cost
of running power to difficult-to-reach locations in order to
meet network design can become a disruption to business
and a drain on resources. To solve this problem, the
DWS-3227P is equipped with 24 10/100/1000BASE-T ports
that support the IEEE 802.3af PoE protocol. The DWS-
3227P is designed to inject up to 15.4 Watts of power per
port on all 24 RJ-45 ports to support IP Phones, Access
Points, Cameras, and more. The DWS-3227P provides
amazing security and flexibility when utilizing the DWS-
3227P’s ‘wireless switching’ features. When used to
power IEEE 802.3af compliant wireless access points,
such as the DWL-2230AP or DWL-7230AP, this ‘wireless-
ready’ switch transforms into a complete wireless
enterprise solution. For devices that are not IEEE 802.3af
compliant, the D-Link DWL-P50 adapter can be used
to supply power to the device making it fully compatible
with any IEEE 802.3af compliant switch. The DWS-3227P
is ideal for today’s popular PoE applications. Best of all,
with 15.4 watts of total power per port, the DWS-3227P
will be capable of providing power to future high wattage
IEEE 802.3af devices such as monitors, scanners, PDA
cradles, cell phone chargers and more, insuring a future
proof network for years to come.
Wireless AP License
The DWS-3227P provides secure, seamless roaming
between access points ensuring clear, uninterrupted
data and voice communication throughout your wireless
network infrastructure. The DWS-3227P 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 AP Management
The DWS-3227P can also centrally manage compatible
wireless access points. No longer will each access point
need to be configured independently. Now your entire
wireless network can be managed through a single
interface. The DWS-3227P includes support for automatic
discovery of APs with real-time monitoring, providing
visibility into utilization and performance of WLAN users
and devices.
Wireless Security
The D-Link DWS-3227P provides enhanced wireless
security features to protect your data. 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.

oaming
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 and break 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-3227P 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. The user’s device will retain its VLAN
membership and IP address, guaranteeing uninterrupted
communication.
Inter-Switch Roaming
The DWS-3227P supports wireless roaming between
access points attached to different switches.
Seamless inter-switch roaming 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.
