DWS-3227P Layer 2+ Stackable Gigabit Wireless Unifi ed Switch
L2+ 24-Port Gigabit PoE Switch with 10 Gigabit Uplinks
Comprehensive Security
The DWS-3227P is equipped to handle many of today’s
emerging security vulnerabilities previously delegated
to only standalone fi rewalls. It incorporates built-in
ACLs for searching out and fi ltering 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 confi guration 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
effi ciency. It also supports an optional Redundant Power
Supply. It includes support for 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 traffi c 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-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 802.1p/
ToS/DiffServ, with classifi cation 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.
Power over Ethernet IEEE 802.3af
Wherever the location—factory, warehouse, campus,
small offi ce, or enterprise facility—the challenge and
cost of running power to diffi cult-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 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
fl exibility 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 802.3af compliant, the
D-Link DWL-P50 adapter can be used to supply power
to the device making it fully compatible with any 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 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 xStack DWS-3227P switch 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 xStack DWS-3227P is capable of centralized
management of compatible wireless access points.
No longer will each individual access point need to be
confi gured independently. Now your entire wireless
network can be managed through a single interface.
The xStack 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 xStack DWS-3227P 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 identifi cation
of APs into “known” and “rogue” classifi cations. The
switch uses the APs to continuously scan radio channels
in an attempt to identify transmissions of unauthorized
WLAN nodes facilitating notifi cation 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-3227P addresses this problem by
bringing AP confi gurations 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-3227P 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 benefi cial feature
when creating a large WLAN environment such as a
campus or multi-fl oor offi ce. Inter-Switch roaming allows
the user complete freedom to roam between switches
located in different buildings or on different fl oors without
disconnection or need for re-authentication.
