Product Description
The xStack DGS-3426 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-3426 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-3426 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-3426 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-3426 includes a Health Check mechanism that provides pro-active network security without the need for manual intervention from the administrator.***
The DGS-3426 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-3426 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.
