DWS-3227
xStack
®
Managed 24-Port Gigabit Stackable L2+ Wireless Switch with
4 Combo SFP, 1 Fixed XFP slot, 2 10-Gigabit Slots, and 10-AP License
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-exclusive
DNA stacking technology allows up to eight DWS-3227
switches to be stacked together and managed as a single
unit, regardless of its physical environment.
Advanced QoS
The DWS-3227 provides a robust and consistent set of
QoS/CoS, supporting eight 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 DWS-3227 provides secure, seamless roaming
between access points to ensure clear, uninterrupted
data and voice communication throughout your wireless
network. 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.
Unified Wireless Switching

Centralized AP Management
The DWS-3227 can also centrally manage compatible
wireless access points. No longer will each individual
access point need to be configured independently. Your
entire wireless network can be managed through a single
interface. The DWS-3227 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 DWS-3227 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.
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 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 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. The user’s device retains its VLAN
membership and IP address, guaranteeing uninterrupted
communication.
Inter-switch Roaming
The DWS-3227 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.
