DLINK DGS-3426P

Switch xStack L2+ 24 Puertos 10/100/1000 PoE gestionable y apilable (19″/1U) con 4 de los puertos Combo Mini-GBIC/1000BaseT/SFP + 2 slots para módulos opcionales de 10Gb con (DEM-410X, DEM-410CX). Apilable hasta 12 unidades de la serie DGS-3400.

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 stack2. 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 Tunnelling1 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 administrator3.

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.
