DXS-3227 Layer 2+ Stackable Gigabit Wireless-Ready Switch

L2+ 24-Port Gigabit Switch with 10 Gigabit Uplinks

network. Furthermore, the DXS-3227 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-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 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. D-Link’s exclusive

DNA stacking technology is also supported, which allows

up to 16* D-Link DXS-3227 switches to be stacked together

and managed as a single unit, regardless of its physical

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.

Centralized Management

The xStack DXS-3227 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-3227 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-3227 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-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 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-3227 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.
