Basic switching RJ-45 Ethernet ports quantity: 24. Full duplex, Networking standards: IEEE 802.1p, IEEE 802.3, IEEE 802.3u, IEEE 802.3z","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.\r\n\r\nThe 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.\r\n\r\nAlternatively, 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.\r\n\r\nThe 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.\r\n\r\nThe 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.","https://images.icecat.biz/img/norm/high/469863-186.jpg","293x200","","","","","","","","","","Ports & interfaces","Basic switching RJ-45 Ethernet ports quantity: 24","Network","Networking standards: IEEE 802.1p, IEEE 802.3, IEEE 802.3u, IEEE 802.3z","Copper ethernet cabling technology: 100Base-TX, 10Base-T","Full duplex: Yes","Data transmission","Supported data transfer rates: 10/100/1000 Mbps","Maximum data transfer rate: 1 Gbit/s","Protocols","Management protocols: SNMP v1/v2c/v3","Other features","Management platform: Web-based, CLI, Telnet","Authentication method: 802.1x, RADIUS/TACACS+","Expansion slots: 3x 10GE","I/O ports: 24x Gigabit Ethernet\n4x Combo SFP","Technical features: IP v.4/v.6 static routing \n1 IP v.6 tunneling"
