In addition, the DXS-3227P also supports IP static routing,
4000 VLANs, up to 64 trunk groups, and is ‘wireless-ready’,
making the DXS-3227P 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-3227P is capable of meeting this
demand and more. With a simple optional firmware upgrade,
the DXS-3227P 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-3227P
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-3227P 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 network. Furthermore, 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.
High Availability
The DXS-3227P 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 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 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 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.
Centralized 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.
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 or jamming
of the rogue signals.
Seamless Roaming
When a user roams between APs connected to different
broadcast domains, the users IP address is no longer
valid after the move to the new AP. This means the users
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 PDA’s
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 users 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.
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 802.11a/b/g as well as support
for Power over 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.
XStack 3200 Wireless AP License
