תאור

The series switches DGS-3120 c software Routed Image (RI) includes switches Level 3, ensuring a secure connection end-user to the network of large enterprises and small and medium-sized businesses (SMB). The switches provide support for multicast and enhanced security features that make this device an ideal solution gigabit aggregation layer. Switch DGS-3120-24TC features 20 ports of 10/100/1000 Mbit / s Gigabit Ethernet and four combo ports 1000BASE-T / SFP Gigabit Ethernet. Switch DGS-3120-24SC equipped with 16-port SFP Gigabit Ethernet and 8-port combo 1000BASE-T / SFP Gigabit. The switches support CardReader for reading memory cards SD, allows booting software and configuration files directly from the SD-card. Furthermore, log files can also be stored on the card.
 
Software Standard Image (SI), Enhanced Image (EI) and Routed Image (RI)
The set switches DGS-3120 series includes three different versions of the software: Standard Image (SI), Enhanced Image (EI) and Routed Image (RI). Switches to the standard version of the software (SI) support advanced features for network construction scale of the campus or enterprise, including advanced settings Quality of Service (QoS), traffic shaping, multicast Layer 2, various security features and functions IPv6, used in networks of new generation IPv6 support or for applications Triple play networks Metro Ethernet.
Software Version Enhanced Image (EI) supports ERPS, Double VLAN (Q-in-Q), Ethernet OAM, Static Route, IMPB and sFlow.
Routed Image (RI) includes support for DHCP-server, VRRP, tunneling IPv6, RIP, OSPF, IGMP, MLD, PIM and DVMRPv3.
 
High reliability
Switches DGS-3120 series are designed for enterprise networks / campus, as well as for users who require high availability and maximum uptime. All models series switches DGS-3120 supports external redundant power supply, thus providing, continuous operation. The switches also support functions 802.1D Spanning Tree (STP), 802.1w Rapid Spanning Tree (RSTP) and 802.1s Multiple Spanning Tree (MSTP), Loopback Detection (LBD), and protection from broadcast storms that enhance network resilience. Thanks to the G.8032 Ethernet Ring Protection Switching (ERPS) provides a failover about 50 ms. For load balancing and fault tolerance by using multiple switches series DGS-3120 supports dynamic 802.3ad Link Aggregation Port Trunking.
 
Enhanced security features
Switches DGS-3120 series software Routed Image (RI) supports the latest security features such as Multi-level access control lists (ACL), protection from storms and IP-MAC-Port Binding (IMPB) with DHCP Snooping. Function IP-MAC-Port Binding allows administrators to bind a source IP-addresses and MAC-address of the user to determine the port number on the switch, thereby prohibiting the user to change the network settings. Moreover, thanks to the DHCP Snooping, the switch automatically detects pairs of IP / MAC-address given by the server, DHCP-tracking packages and storing them in a "white list" IMPB. In addition, the function of D-Link Safeguard Engine identifies and prioritizes packets for processing CPU, to prevent network attacks and protect the management interface on the switch.
 
Identity Driven Network Policies
Switches DGS-3120 Series supports authentication mechanisms such as an 802.1X, Access Control Web-based interface (WAC) and access control MAC-based, easy deployment. After authentication, individual policies such as belonging to a VLAN, QoS policies, and ACL rules can be assigned to each host. In addition, the switch supports Microsoft® NAP (Network Access Protection). NAP technology allows users to deny access to a network of computers that do not meet the safety requirements.
 
Traffic Management for Triple Play services
DGS-3120 series provides a set of features multi-level QoS / CoS, to ensure that critical network services such as VoIP, video conference, IPTV and IP-surveillance are served with proper priority. Options Traf fi c Shaping provide guaranteed bandwidth for data services in the case of high network load. With the support of multicast Layer 2 Switch DGS-3120 implements IPTV-processing applications using the growing market demand. IGMP / MLD Snooping allows host-based connection of multiple customer multicast group to a single interface. When you use the ISM VLAN multicast traffic for the purpose of efficient spending of bandwidth and enhance network security is transferred in a separate VLAN. ISM VLAN profiles allow users to quickly and easily assign / change the preset settings on ports multicast subscribers.
 
Effective management
For the implementation of the Agreement on the level of quality of service SLA (Service Level Agreement), service providers must reduce the mean time to repair performance device (Mean Time to Repair - MTTR) and increase service availability. A functional Ethernet OAM contributes to solving these problems and allows service providers to ensure the best quality of service. Switches DGS-3120 supports standardized OAM, including IEEE 802.3ah, IEEE802.1ag and ITU-T Y.1731. Connectivity Fault Management (CFM) provides monitoring functions, and troubleshooting networks Ethernet, allowing you to control the connectivity, isolate network issues, and identify customers affected by network issues.
 
IPv6 Technology
Switches DGS-3120 series is fully compatible with the next-generation networks based on IPv6 protocol and IPv6 support remote management via telnet, HTTP or SNMP. To organize secure IPv6-network switches DGS-3120 Series uses IPv6 ACL, DHCPv6 Snooping and functions Neighbor Discovery (ND) to protect the network from unauthorized IPv6-customers. The series has successfully passed the certification IPv6 Logo Phase 2 from the IPv6 Forum, a global alliance of industry, whose main activity is to ensure the implementation and development of technology IPv6. Certification Program IPv6 Ready Logo testing equipment provides IPv6 interoperability and compliance protocols.
 
Green Technology
D-Link is a leader in the development of innovative energy-saving technology that does not sacrifice performance or functionality. Switches DGS-3120 series support the technology D-Link Green, which allows the use of power-saving mode, lower the heat and automatically reduces power consumption depending on the length of the cable. The power saving feature automatically powers down ports. Smart Fan function automatically turns on the built-in fans at a certain temperature, providing continuous, reliable and eco-friendly operation of the switch. The switch also supports Energy Efficient Ethernet (EEE), which reduces operating costs.
 
Management
Function D-Link Single IP Management (SIM) simplifies and speeds up the administration, since it is possible to configure, monitor and maintain multiple switches connected to the same IP-address from any computer with support for Web-browser. Through the use of this technology in the management of all devices in the virtual stack are treated as a single entity and managed through a single IP-address. Switches DGS-3120 series supports standard management protocols such as SNMP, RMON, Telnet, Console, Web-interface, and authentication protocols SSH / SSL.
