Introducing the D-Link DGS-3100-48 gigabit stackable switch is designed for growing companies looking for scalability and robust security features. The D-Link DGS-3100-48 is equipped with robust features that fulfill the most demanding network needs in today’s multimedia-intensive world. Stackable up to 6 units under a single IP, the DGS-3100-48 provides a total of 20Gbps full-duplex of fixed stacking bandwidth. Designed with efficient QoS features, the DGS-3100-48 facilitates smooth videos and jitter-free VoIP deployments. To help secure your network, D-Link implements both the Safeguard Engine to prevent Denial-of-Service attacks, and Access Control Lists to enhance security to your network. The DGS-3100-48 is equipped with industry standard management features such as an easy-to-use web-based administrator interface and CLI interface. D-Link provides features on a cost-effective platform that will increase your company’s productivity and protect your investment.

Stackable up to 6 Units
The DGS-3100-48 includes two built-in stacking ports that can provide up to 20Gbps in stacking backplane. This will enhance your overall network performance for those switches transmitting large files. Under stacking mode, the switch is hot-swappable meaning 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; simply give the new switch the same stack number ID as the old switch and the new switch will carry the same configuration as before. This minimizes the downtime of a network and maximizes the productivity of your business. Also, cross stack port mirroring and port trunking are supported to facilitate network administration.

The D-Link Safeguard Engine and Security
The DGS-3100-48 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 Denial of Service attack is waged against the DGS-3100-48, the D-Link Safeguard Engine detects the threat and prevents an overload of the central processor, ensuring network integrity and helping to maintain open network bandwidth channels.

In addition, D-Link switches support 802.1x authentication, which is a secure implementation that allows users to log onto your network. When used in conjunction with a RADIUS server, 802.1x requires each workstation attached to the DGS-3100-48 to provide a username and password before gaining access to the local area network. D-Link also utilizes security features such as the Access Control List, allowing an administrator to restrict the access of a network through a variety of means including MAC address, IP, UDP/TCP, and even VLAN ID. Time-based ACL* is especially useful for K-12 or college environments when access can be limited based on time.

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 DGS-3100-48, which supports 802.1p Quality of Service (Qos) with 4 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 always clear and jitter-free. Video traffic can also be assigned with the same priority. In addition, the DGS-3100-48 provides IGMP Snooping, which allows the forwarding of multicast packets without increasing network broadcast congestion. By snooping IGMP registration information within a frame, a list of workstations who 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-3100-48 supports MLD snooping*. The DGS-3100-48 also supports 802.1Q VLANs, allowing QoS and security to be achieved on a data laden network.

Ease of Management
The DGS-3100-48 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. Users can interface using either an intuitive web-based browser graphic interface or a standard Command Line Interface (CLI), both of which are protected through SSL or SSH encryptions.
