D-Link xStack DXS-3250 Managed Stackable Ethernet Switch - 48 x 10/100/1000Base-T LAN - 4 x SFP, 2 x Expansion Slot - Managed Ethernet Switch

D-Links 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 todays 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-Links 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.
