Gigabit Switch DGS-3000 Series is a line of managed switches D-Link Layer 2 and are intended for use in networks Metro Ethernet. DGS-3000-26TC equipped with two ports of 10G SFP +, which guarantees high performance gigabit aggregation of a large number of compounds. Switches DGS-3000 series are made in a 1U and suitable for desktop installation or for installation in the telecommunications closet. DGS-3000-10TC made in a more compact 9-inch housing that provides better air circulation in the confined space of the telecommunication closet and simplifies cabling infrastructure. Provided for in the DGS-3000-26TC port Alarm allows you to connect external alarm devices to detect potential threats, such as opening doors or overheating in the closet, which is triggered off an alarm. This functionality is very useful for devices used in urban networks and provider networks.
All Ethernet-ports switches DGS-3000 series are equipped with built-in protection against static electricity to 6 kV, allowing the device to protect against power surges, especially if the cables are Ethernet-located in an open space or in old buildings. In the event of power failures in the switches, an additional connector for redundant power supply DPS-200 or a DC power supply with a voltage of 12 V. For failover Ethernet-channel devices supports protocol 802.1D Spanning Tree (STP), 802.1w Rapid Spanning Tree (RSTP) and 802.1s Multiple Spanning Tree (MSTP), the use of which allows you to automatically backup data path. Using this functionality allows the transmission and reception of frames even when faults occur in the network. The switches also support Ethernet Ring Protection Switching (ERPS, ITU-T G.8032), whereby the recovery operation after a failure of the ring does not exceed 50 ms. Using detection loops Loopback Detection (LBD) prevents overloading at uncontrolled network segments administered by subscribers or constructed on the basis of unmanaged switches. In addition, the series switches DGS-3000 supports port aggregation functionality of standards-based 802.1AX and 802.3ad, the use of which allows you to combine multiple ports into a group, while increasing bandwidth and improving the fault-tolerant connections to ensure smooth operation and load balancing across multiple network devices .
Triple Play Service
The series switches DGS-3000 is a wide set of functions Layer 2 multicast, including IGMP / MLD Snooping, Fast Leave, and filtering. Support for this functionality provides the ability to work with IPTV-services that are gaining popularity with each passing year and are increasingly in demand in the market. Application features IGMP / MLD Snooping allows host-based connection of multiple IPTV-subscribers to one network interface. When you use the ISM VLAN multicast transmission is performed in a separate VLAN, which promotes effective spending of bandwidth. ISM VLAN profiles allow users to quickly and easily assign or change the preset settings for ports multicast subscribers. Support for IGMP Authentication eliminates the possibility of unauthorized IPTV-subscription due to conduct authentication set-top boxes.
Switches DGS-3000 series support the advanced functionality of QoS (Quality of Service) to provide quality service Triple Play. Packet classification is based on various header fields or user-defined packet content, allowing traffic prioritization. The use of markers "Two speed, three-colored marking" and "One speed three color labeling" (trTCM / srTCM) allows you to classify traffic to maximize bandwidth for priority traffic. By using the bandwidth management providers will be able to determine the level of bandwidth of incoming / outgoing channel per port increments up to 64 kbit / s.
Ease of maintenance, efficient troubleshooting
Implemented in the switches support extended functionality OAM (Operation, Administration and Management) can significantly simplify maintenance, and troubleshooting. By using the diagnostics cable, you can remotely monitor the status of Ethernet-cable and determine the location of a fault, allowing the provider to reduce the maintenance costs of the equipment. Function Connectivity Fault Management (CFM, IEEE 802.1ag) is designed for monitoring and troubleshooting in End-To-End Ethernet-networks, giving service providers the ability to perform the connection test to isolate the problematic segments of the network and identify the users of such segments. Technology D-Link Unidirectional Link Detection (DULD) allows you to track the problem of fiber optic connections, and thereby improve the stability of the cable infrastructure networks MAN (Metropolitan Area Network).
High level of safety and efficiency
The series switches DGS-3000 provides advanced functionality of user authentication / devices, including 802.1X, Access Control Web-based interface (WAC) ² and MAC-address (MAC). Options WAC² and MAC allows network administrators to authenticate the user / device and manage the security of the network without the need to install client software, which is very important if the software is installed on the equipment of the customer is not possible. Also switches DGS-3000 series support the functional Compound Authentication², giving network administrators a choice of several methods of authentication for a single device. Host-based authentication provides precise control access to each device on the network. For integration with billing systems and services supports protocols RADIUS and TACACS. Provided for in DGS-3000 Series feature IP-MAC-Port Binding (IMPB) provides strong binding to the addresses and interfaces, and ARP Spoofing Prevention - protects the network from attacks such as Man-In-The-Middle and ARP Spoofing.
To ensure the smooth operation of the network switches DGS-3000 series has a mechanism D-Link Safeguard Engine to protect the CPU from malicious broadcast traffic congestion caused by viral activity. The switches also support DHCP Screening, provides filtering DHCP-requests from unauthorized DHCP-servers or routers. Application protection functions BPDU / DoS-attacks and filtering L3 Control Packet Filtering allows you to increase the level of network security.
Support for IPv6
The DGS-3000 Series supports functional IPv6, including MLD Snooping, WAC², IPv6 ACL / QoS and IMPBv6, which promotes easy equipment integration in next-generation networks. In addition, this series supports both protocol stacks IPv4 / v6, allowing the switches to act as a bridge between IPv4 and IPv6. All models DGS-3000 successfully passed the certification IPv6 Logo Phase 2, which proves their full conformance and interoperability when using IPv6-networks.
