Product Description
The xStack DGS-3426P 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-3426P 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 CX4 cable, the DGS-3426P 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-3426P provides up to 15.4W power on all 10/100/1000 Mbps ports. It complies with the IEEE 802.3af standard, delivering power over cat5 Ethernet cable for PoE-capable wireless APs, IP cameras and IP phones.
The DGS-3426P 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-3426P 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-3426P 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.
