DWS-3227

Overview

The D-Link

xStack

3200 Series switches are designed to

provide effortless wireless convergence with traditional

Layer 2 data access switching, emphasizing security,

performance, and resiliency. Featuring the latest stacking

technology from D-Link, the DWS-3227 can stack up to eight

units, providing up to 200 Gigabit ports. It can stack with other

D-Link switches such as the DXS-32 50, DXS-3227P, and

DXS/DWS-3227, providing extraordinary flexibility. It provides

24 built-in copper Gigabit ports, including four combo SFP

slots for easy, flexible connection to fiber-based Gigabit

media. The DWS-3227 is also equipped with two module

slots that support 10-Gigabit Ethernet for both copper CX-4

and fiber XFP connections, as well as one fixed 10-Gigabit

XFP slot for a total switching capacity of up to 120Gbps. In

addition, the DWS-3227 supports IP static routing, 4000

VLANs, up to 64 trunk groups, and is ‘wireless-ready’,

making the DWS-3227 the most feature-rich, high-capacity

switching solution in its class by far. The DWS-3227 comes

standard with a 10-client AP license upgradeable to 50 and

is capable of supporting 50 APs per switch/stack with up to

600 WLAN clients.

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 DWS-3227 is capable of meeting this

demand and more. With a simple, optional firmware

upgrade, the DWS-3227 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

demand mobility and seamless integration such

as PDA and 3G/VoIP mobile phones. With an optional

software upgrade, the DWS-3227 becomes a wireless

switch providing secure, seamless roaming between

access points ensuring clear, 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 the latest

3200 Series of xStack switches. Switches built with DNA

are easily stackable with little or no system downtime for

expansion. For example, the xStack 3200 Series switches

self-heal 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 10-Gigabit interface

or using a 1000Base-X port to connect between wiring

closets. The 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 xStack 3200 Series switches

allow 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 allows 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 DWS-3227 handles many security vulnerabilities

previously delegated to standalone firewalls. It supports

Access Control Lists (ACLs) based on MAC address,

switch port, IP address, and/or TCP/UDP port numbers.

The DWS-3227 also features 802.1X Authentication, Guest

VLAN, and RADIUS and TACACS+ for strict access control

over the network. Additionally, port-based security can

help to protect network integrity. Port numbers can be

pre-programmed for specific applications, allowing these

applications to provide faster service and reduce load on

the CPU.
