The general trademark of a manufacturer by which the consumer knows its products. A manufacturer can have multiple brand names. Some manufacturers license their brand names to other producers.
Product name:
Product name is a brand's identification of a product, often a model name, but not totally unique as it can include some product variants. Product name is a key part of the Icecat product title on a product data-sheet.
xStack 24-Port Gigabit L2+ Stackable Switch
Product code :
The brand's unique identifier for a product. Multiple product codes can be mapped to one mother product data-sheet if the specifications are identical. We map away wrong codes or sometimes logistic variants.
Category :
A switch is a device with which it is possible to connect computers into a (local area) network, provided your computers all have an appropriate networking device installed. Switches can be daisy chained to form larger networks and come in managed and unmanaged variaties. The unmanaged versions generally cannot filter data and will forward any data that is fed into them, so they are better suited for small networks. Switches are easy to set up (just plug in the network cables) and allow you to share printers, storage space and other network resources with your entire home or office network.

Data-sheet quality: created/standardized by Icecat
The quality of the product data-sheet can be on several levels:
only logistic data imported: we have only basic data imported from a supplier, a data-sheet is not yet created by an editor.
created by D-Link: a data-sheet is imported from an official source from a manufacturer. But the data-sheet is not yet standardized by an Icecat editor.

The official marketing text of D-Link xStack 24-Port Gigabit L2+ Stackable Switch as supplied by the manufacturer
The xStack DGS-3427 next generation switch delivers performance, flexibility, security, multi-layer Quality of Service (QoS) and redundant power option for the SMB and enterprises. With high Gigabit port densities for desktop connections, SFP fibre connectivity, 10-Gigabit uplink options and enhanced Layer 2+ functions, this switch comprises the workgroup access-layer stack for seamless integration with L3 core switches to form part of a multilevel network structured with high-speed backbone and centralized servers.

The DGS-3427 can operate as a stand-alone device or part of a scalable stack. Embedded with Single IP Management capability, a stand-alone switch can form part of a virtual stack, where intra-stack traffic flows through the usual network wires, doing away with the costly stacking cables. Without stacking cables, cable distance barriers and physical stacking limitations, a virtual stack can comprise units that are located anywhere on the network that minimizes the impact of any single point of failure.

Alternatively, optional 10-Gigabit modules can be installed in the open slots to create a physical stack. Up to 12 units or 288 Gigabit ports can be configured for a stack. Users can install one or two single-port modules, depending on whether the fault-tolerant Ring or Star stacking is implemented. With each of these ports providing 20Gbps full duplex transmission on the cost-effective coaxial cable, the DGS-3427 provides not only high-bandwidth stacking but also cost control capability that allows users to add ports strictly on a per need basis. Modules with single 10-Gigabit XFP can also be installed in any of the open slots for uplink to a server or a fibre backbone.

The DGS-3427 provides a complete set of security features, which includes L2/L3/L4 multi-layer Access Control Lists and 802.1x user authentication via TACACS+ and RADIUS servers. In addition, it offers suppression capabilities, Layer 3 IP v.4/v.6 Static Routing and IP v.6 Tunnelling to increase network performance and security. To ensure that not only proper user access is served, but also malicious traffic within the network is prevented, the DGS-3427 includes a Health Check mechanism that provides pro-active network security without the need for manual intervention from the administrator.

The DGS-3427 provides extensive VLAN support including GARP/GVRP, 802.1Q and asymmetric VLAN to enhance security and performance. To support converged applications including VoIP, ERP, Intranet and videoconference, a robust set of L2/L3/L4 QoS/CoS features ensures that critical network services are served with proper priority. With Multi-layer L2/L3/L4 bandwidth control and D-Link Safeguard Engine, the DGS-3427 can set limits to traffic flows from the edge of the network while automatically prevents broadcast packets and bulk traffic generated by Internet DoS-related activities from utilizing the switch's CPU resources. This prevention of unnecessary and harmful traffic can increase the overall network serviceability, reliability and availability of the stack.
