DXS-3227
xStack
®
Managed 24-Port Gigabit Stackable L2+ Switch
with 4 Combo SFP, 1 Fixed XFP Slot, and 2 10-Gigabit Slots
High Availability
The DXS-3227 supports “Shortest-Path” switching, which
improves resiliency, uptime, and network efficiency. It
includes support for 802.3ad Link Aggregation and 802.1w
Rapid Spanning Tree for increased network reliability and
availability. It also supports an optional Redundant Power
Supply (DPS-500).
Network Management
The DXS-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. The
D-Link-exclusive DNA stacking technology allows up
to eight DXS-3227 switches to be stacked together and
managed as a single unit, regardless of the environment.
Advanced QoS
The DXS-3227 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.
Wireless AP License
The xStack DXS-3227 switch provides secure, seamless
roaming between access points, to ensure clear,
uninterrupted data and voice communication throughout your
wireless network. The DXS-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 DXS-3227 can also centrally manage compatible
wireless access points. No longer will each access point
need to be configured independently. Your entire wireless
network can be managed through a single interface. The
DXS-3227 includes support for automatic discovery of APs
with real-time monitoring, providing visibility of all WLAN
users and devices.
Wireless Security
The DXS-3227 provides enhanced wireless security
features to protect your data. Support for WEP, WPA™
and WPA2™ encryption guarantees your network’s
privacy. Rogue AP detection and containment ensure
that only the APs you install function on your network.
AP detection identifies APs as “known” and “rogue”.
The switch uses the APs to continuously scan radio
channels, identifying transmissions of unauthorized
WLAN nodes and jamming rogue signals.
Seamless Wireless Roaming
When roaming between broadcast domains, a user’s
IP address may become invalid. 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 to provide seamless
roaming between APs on different subnets becomes
essential to maintaining active sessions and VoIP calls.
The DXS-3227 brings AP configuration and support directly
to the switch. This allows the user to move between
access points seamlessly. 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 for
uninterrupted communication.
Inter-switch Roaming
The DXS-3227 supports 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 extremely beneficial
in a large WLAN environment, such as a campus or multi-
floor office. Inter-switch roaming allows complete freedom
to roam between switches located in different buildings
or on different floors without disconnection or need for
re-authentication.
