Overview
The D-Link xStack 3200 Series switches are designed to
provide effortless wireless technology convergence with
traditional Layer 2 data access switching, emphasizing
security, performance, and resiliency. Featuring the latest
stacking technology from D-Link, the xStack DWS-3227P
can stack up to 8 units, providing up to 200 Gigabit ports. It can
stack with other D-Link switches such as the DXS/DWS-3250,
DXS/DWS-3227, and DXS/DWS-3227P, providing extraordinary
flexibility. It provides 24 built-in copper Gigabit ports,
including 4 combo SFP ports for easy, flexible connection to
fiber-based Gigabit media. The DWS-3227P is also equipped
with 2 module slots that support 10 Gigabit Ethernet for both
copper CX-4 and fiber XFP connections, as well as 1 fixed
10GbE XFP port. When stacking through CX-4 interfaces, a
stacking bandwidth of 48Gbps can be achieved, for a total
switching fabric capacity of up to 120Gbps. In addition, the
DWS-3227P also supports IP static routing, 4000 VLANs, up
to 64 trunk groups, and is 'wireless-ready', providing wireless
roaming, centralized AP management, and rogue AP
detection in a single switching solution. The DWS-3227P
comes standard with a 10 client AP license upgradeable
up 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-3227P is capable of meeting this demand
and more. With a simple optional firmware upgrade, the
DWS-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 demand mobility and seamless
integration such as PDA and 3G/VoIP mobile phones. With
an optional software upgrade, the DWS-3227P 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 3200 Series
of xStack switches by D-Link. Switches built with DNA are
easily stackable with little or no system downtime for
expansion. For example, the DWS-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 they be through a 10 GbE interface or
using a 1000Base-X port to connect between wiring closets.
The DWS-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 DWS-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 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.
