D-Link xStack DXS-3227P- Datasheet page 2

Comprehensive Security
The DXS-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 DXS-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 DXS-3227P supports "Shortest-Path" switching,
which improves resiliency, uptime and network
efficiency. 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 DXS-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 16 D-Link DXS-3227P
switches to be stacked together* and managed as a
single unit, regardless of its physical environment.
Advanced QoS
The DXS-3227P 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.

Power over Ethernet IEEE802.3af
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 DXS-3227P is equipped with 24
10/100/1000BASE-T ports that support the 802.3af PoE
protocol. The DXS-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
DXS-3227P provides amazing security and flexibility
when utilizing the DXS-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 PoE adapter can be used to supply power to
the device making it fully compatible with any 802.3af
compliant switch. The DXS-3227P is ideal for today's
popular PoE applications. Best of all, with 15.4 watts of
total power per port, the DXS-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 DXS-3227P switch provides secure, seamless
roaming between access points ensuring clear,
uninterrupted data and voice communication throughout your
wireless network infrastructure. The DXS-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 DXS-3227P 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 DXS-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 DXS-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 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 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 DXS-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 users 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 DXS-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 upon 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.
