DGS-3120-48PC/*RIEOL
תאור
The series switches DGS-3120 c software Routed Image (RI) includes switches, Layer 3, provide a secure connection end-users to networks of large enterprises and small and medium businesses (SMB). The switches support advanced security features, making them an ideal Gigabit access layer solution or aggregation, depending on the task at hand. Model DGS-3120-24PC / 48PC equipped with 20 and 44 ports of 10/100 / 1000Base-T, respectively, and 4 combo ports 1000Base-T / SFP. All ports are 10/100 / 1000Base-T Data switches support Power over Ethernet technology standard 802.3af and 802.3at. By default, the total budget power - 370 watts, which can be increased up to 760 watts when using the optional power supply DPS-700. The switches support CardReader for reading memory cards SD, which allows downloading of software and configuration files directly from the SD-card and save her log files.
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, a variety of security features and functions of IPv6, used in the networks of the new generation IPv6 support for applications or 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, Policy-based Routing (PBR), 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 802.3ad Link Aggregation.
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 the storm, 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 prioritize packets destined 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 802.1X, Access Control Web-based interface (WAC) and access control MAC-based, providing easy deployment. After authentication, individual policies such as belonging to a VLAN, QoS policies and rules ACL, can be assigned to each host. In addition, the switch supports Microsoft® NAP (Network Access Protection). Technology NAP 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, 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 a 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 efficient bandwidth consumption and improve network security is transferred to 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. Ethernet OAM features contribute 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, IEEE 802.1ag and ITU-T Y.1731. Connectivity Fault Management (CFM) provides monitoring functions, and troubleshooting networks Ethernet, allowing you to control the connection, isolate network issues, and identify customers affected by network issues.
IPv6 Technology
Switches DGS-3120 series is fully compatible with the networks of the next generation IPv6-based remote management and support IPv6 over telnet, HTTP or SNMP. For 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 the 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 limiting the functionality of the device. 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 feature automatically turns on the built-in fans at a certain temperature, providing continuous, reliable and sustainable performance of the switch. The switch also supports Energy Efficient Ethernet (EEE), which reduces operating costs.
Office
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.
