DGS-3000-28SCמיועד לפרויקטים
תאור
Switch DGS-3000-28SC is a line of managed switches D-Link 2 levels and is designed for use in networks Metro Ethernet. The switch is equipped with a 4-port 10GBase-X SFP +, which guarantees high performance gigabit aggregation of a large number of compounds. DGS-3000-28SC made in a 1U and is suitable for desktop installation or for installation in the telecommunications closet.
Reliability
All Ethernet-switch ports DGS-3000-28SC 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-in open space or in old buildings. In the event of power failures in the switch, an additional connector for redundant power supply DPS-200A / 500A and DPS-500DC / B1 or DC power supply with a voltage of 12 V. In order to ensure fail-safe Ethernet-channels in the switch 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 switch DGS-3000-28SC support port aggregation functionality based on standard 802.1AX, 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 switch DGS-3000-28SC implemented a wide range of functions multicast Layer 2, 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. 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.
Switch DGS-3000-28SC support advanced functionality 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. 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 switch DGS-3000-28SC provides extended functionality of user authentication / devices, including 802.1X, Access Control Web-based interface (WAC) and MAC-address (MAC). Options WAC 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 when installing the software on the client equipment is not possible. The switch DGS-3000-28SC support functional Compound Authentication, providing network administrators with a choice of several methods of authentication for a single device. Authentication is based on the unit provides precise control access to each device on the network. For integration with billing systems and services supports protocols RADIUS and TACACS. Provided in the switch DGS-3000-28SC function 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 switch DGS-3000-28SC a mechanism D-Link Safeguard Engine to protect the CPU from malicious broadcast traffic congestion caused by viral activity. The switch also supports 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 switch DGS-3000-28SC supports functional IPv6, including MLD Snooping, WAC, 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.
