Product Description:

Designed to provide aggregation for servers in data centers, the DXS-3250E xStack® Managed Layer 2 switch emphasizes security, performance, and resiliency.

The D-Link® xStack® DXS-3250E switch is designed to provide aggregation for servers in data centers with an emphasis on security, performance, and resiliency. With a hot swappable power supply and removable fan tray in a 2U case, the xStack DXS-3250E can be used to optimize switching performance in a rack server configuration. It provides 48 built-in copper Gigabit ports, including four combo SFP ports for easy, flexible connection to fiber-based Gigabit media. It is also equipped with one module slot that supports optional 10-Gigabit Ethernet for two XFP fiber connection.

Load-Sharing Power Supply For Non-Stop Redundancy
The xStack DXS-3250E supports two power supply trays for redundancy and continuous support. Each switch contains one internal power supply tray with one slot for an optional additional power supply tray, which can be installed for redundancy and load sharing. Both trays are located in the front of the switch for convenient access. In the event of a failure of one tray, power will immediately failover to the other active tray without interrupting or affecting the system. The failed power supply tray can be removed and replaced by a new power supply tray without powering down the switch, thus maximizing the uptime of the network. The DXS-3250E also has a removable fan tray that can easily be accessed and replaced.

Security at the Edge
The DXS-3250E is equipped to handle many of today’s emerging security vulnerabilities at the edge, where malicious attacks come from within the network. It features the D-Link advanced Safeguard Engine™, which 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 be set up to protect the integrity of the network. Furthermore, the DXS-3250E protects against attacks towards the CPU itself and improves utilization to meet existing network demands to maximize the device’s responsiveness to user configuration activities.

Other common security issues on the edge include rogue DHCP servers, man-in-the-middle attacks, and access control. To address these potential vulnerabilities and manage the integrity of the network, the DXS-3250E supports DHCP Snooping, DHCP Option 82, and Access Control List. For authentication, the DXS-3250E supports 802.1x and TACACS+.

Voice and Video Requirements
The DXS-3250E provides a robust and consistent set of QoS/CoS, supporting eight priority queues for 802.1p/ToS/DiffServ, with classification and marking based on MAC SA/DA, IP SA/DA, and/or TCP/UDP. The DXS-3250E also supports IEEE 802.3ad Link Aggregation for bandwidth management. Other traffic management features include: Layer 3 static routing, bandwidth control, broadcast storm control, and private VLAN Edge. For multicast traffic, IGMP snooping v1/2/v3 and IGMP query are supported.

Besides multicast forwarding, the DXS-3250E also supports Multicast TV. In today’s deployment for IPTV, this feature is crucial for bandwidth management. Multicast TV allows subscribers to join the same multicast stream, even if the subscribers are not members of the same VLAN, eliminating television traffic duplication.

Network Management
The DXS-3250E features a variety of network management options: Industry standard console CLI, Telnet, easy-to-use Web Graphic Interface, and SNMPv1/2c/3. Administrative access can be secured through SSH2/SSLv3. It also features 802.1w Rapid Spanning Tree to increase network reliability and availability.

For larger networks, 802.1s Multiple Spanning Tree is supported to provide up to 15 instances per switch. To monitor traffic, the DXS-3250E supports RMON and port mirroring. The xStack® switch also allows dual firmware image and configurations to be stored to ease deployments. Furthermore, cable diagnostics is included to minimize deployment issues that may be associated with bad cables.
