D-Link’s xStack 3200
series Switches are designed to provide effortless wireless technology
convergence with traditional Layer 2 data access switching, emphasizing
on security, performance, and resiliency. Featuring the latest stacking
technology from D-Link, the xStack DXS-3250 can stack up to 16
units in a stack providing up to 768 Gigabit ports. It can stack with
other D-Link switches such as the (DXS-3227, DXS-3227P), providing
extraordinary flexibility. It provides 48 built-in copper Gigabit
ports, including (4) combo SFP ports for easy, flexible connection to
fiber-based Gigabit media. The DXS-3250 is also equipped with 2 module
slots that support 10 Gigabit Ethernet for both copper CX-4 and fiber
XFP connections. When stacking through CX-4 interfaces, a stacking
bandwidth of 48Gbps can be achieved, for a total switching fabric
capacity of up to 144Gbps. In addition, the DXS-3250 also supports IP
static routing, 4000 VLANs, up to 64 trunk groups, and is
‘wireless-ready’, making the DXS-3250 the most feature rich, high
capacity switching solution in its class by far.
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 DXS-3250 is capable of meeting
this demand and more. With a simple optional firmware upgrade, the
DXS-3250 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 has become crucial for wireless technologies
deployed in real-time inventory, data mining, and an array of personal
electronics that demands mobility and seamless integration such as PDA
and 3G/VOIP mobile phones. With an optional software upgrade, the
DXS-3250 becomes a wireless switch providing secure, seamless roaming
between access points ensuring clear, uninterrupted data and voice
communication throughout your wireless network infrastructure.
Comprehensive Security
The DXS-3250 is equipped to handle many of today’s emerging security
vulnerabilities previously delegated to only stand-alone firewalls. It
incorporates built in ACLs for searching out and filtering such threats
as: Denial of Service attacks, Trojan Horses, Worms, and more. Other
access rules can also be set up to prevent network, and 802.1x
authentication login. In addition, port based security can also be set
up to protect the integrity of the network. Furthermore, the DXS-3250
protects against attacks towards the CPU itself, and improves
utilization to meet existing network demands to maximize device
responsiveness to user configuration activities. In addition,
well-known port numbers for allowed applications can be pre-programmed,
which will allow these applications faster service, and reduce the load
on the CPU.
High Availability
The DXS-3250 supports
“Shortest-Path” switching which improves resiliency, uptime and network
efficiency. It also supports an optional Redundant Power Supply
(DPS-600). It includes support for 802.3ad Link Aggregation, and 802.1w
Rapid Spanning Tree for increased network reliability and availability.
Network Management
The DXS-3250 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 stacking
technology is also supported, which allows up to 16 D-Link DXS-3250
switches to be stacked together and managed as a single unit,
regardless of its physical environment.
Advanced QoS
The DXS-3250 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.
