The latest generation of D-Link xStack switches support IPv6 routing and have more advanced features than ever to address today’s concerns regarding security, QoS, and management. The xStack DGS-3650 is a 48-Port gigabit managed switch with 4 combo SFP slots and 2 optional 10Gigabit uplinks for stacking. The D-Link DGS-3650 is equipped with robust features that fulfill the most demanding network for voice and video streaming. The DGS-3650 is stackable up to 12 units with 40Gbps full-duplex of stacking bandwidth fixed-in. To help secure your network, the D-Link Safeguard Engine helps prevent Denial-of-Service (DoS) attacks while the Access Control List (ACL) enhances security of your network. The DGS-3650 is equipped with industry standard management features including an easy-to-use web-based administrator interface and a standard CLI interface. D-Link provides these features on a scalable platform that increases your company’s productivity while protecting your investment.

IPv6 and IPv4 Routing
The xStack DGS-3650 provides current IPv4 networks with a simple migration path to IPv6 and protects your investment for future network upgrades when greater security and larger addressing are required. Basic static routing such as RIP and RIP2 are supported for small network routing applications. Advanced routing protocols such as OSPF and equal cost routing are supported for load balancing and building a scalable network.

Stackable Up to 12 Units
The xStack DGS-3650 has two optional ports to install stacking modules that provide up to 40Gbps in data stacking backplane, full-duplex. This enhances your overall network performance for those switches transmitting large files such as graphics or pictures. Under stacking mode, the switches are hot-swappable. This means that in a stack configuration, any of the switches can be replaced or removed without affecting the network. There is no need to reconfigure a replacement switch; just give the new switch the same stack number ID as the old switch and the network will carry the same configuration as before. This minimizes the downtime of a network and maximizes the productivity of your business. Also, to facilitate network administration, cross stack port mirroring and port trunking are supported.

The D-Link Safeguard Engine and Security
The DGS-3650 incorporates advanced mechanisms to detect an attack against the central processing unit of the switch and to take corrective action on the attacking interface. When a DoS attack is waged against the DGS-3650, the D-Link Safeguard Engine detects the threat and prevents overload of the central processor thus ensuring network integrity and helping to maintain open network bandwidth channels.

In addition, the D-Link xStack DGS-3650 offers a variety of authentication methods, including those without the requirement of a RADIUS server. It supports MAC based Access Control (MAC), which authenticates the user based on the MAC address of the client so that authentication is transparent to the client. It also supports Web-based Access Control (WAC), which prompts for username and password before allowing access to TCP traffic. Lastly, the xStack DGS-3650 supports Network Access Protection (NAP). This feature works in conjunction with Microsoft® software platforms such as Vista® to reinforce health and security policies of the network, including policy validation, network restriction, remediation, and ongoing compliance.

Voice and Video Applications
For today’s business, having voice, data, and video on the same network is common practice. This challenge is met by the D-Link xStack DGS-3650, which supports 802.1p with 8 queues. The administrator can designate the priority of the traffic based on a variety of means including IP and MAC address, so that voice data is clear and jitter-free. Video traffic can also be assigned with the same priority. In addition, the D-Link xStack DGS-3650 provides IGMP Snooping, which allows the forwarding of multicast packets such as streaming audio and video without increasing network broadcast congestion. By snooping IGMP registration information within a frame, a list of workstations that have joined the multicast group is created. This list then allows the switch to intelligently forward packets to only the appropriate member workstations. For IPv6 traffic, the DGS-3650 supports MLD snooping. Multicast routing is supported under independent multicast protocol, including PIM-SM and PIM-DM. DVMRP is also supported to interconnect two multicast-enabled networks across non-multicast networks. In conjunction with support for 802.1Q VLANs, Quality of Service (QoS) and security can be achieved on a network infused with data traffic.

Ease of Management
The DGS-3650 supports SNMP v1/2/3 so traps can be set on abnormal events and information can be polled to maximize the productivity of the network. Other standard management features also supported include RMON and IEEE 802.1d Spanning Tree. User interfaces include an intuitive web-based GUI or standard CLI, with administration traffic protected through SSL or SSH encryptions
