DGS-3000-28SC
The DGS-3000-28SC switch is part of the D-Link Level 2 line of managed switches and is designed for use in Metro Ethernet networks. The switch is equipped with 4 10GBase-X SFP+ ports, which guarantees high performance when aggregating a large number of gigabit connections. The DGS-3000-28SC is made in a 1U high housing and is suitable for both desktop installation and installation in a telecommunications cabinet.
Reliability
All Ethernet ports of the DGS-3000-28SC switch are equipped with built-in protection against static electricity up to 6 kV, which allows you to protect the device from voltage surges, especially if the Ethernet cables are located in an open space or in old buildings. In case of power outages, the switch has an additional connector for connecting a backup power supply DPS-200A/500A and DPS-500DC/B1 or a DC power supply with a voltage of 12 V. To ensure fault tolerance of Ethernet channels, the switch supports the protocols 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 reserve data transmission routes. The use of this functionality ensures the transmission and reception of frames even in the event of network failures. The switches also support Ethernet Ring Protection Switching technology (ERPS, ITU-T G.8032), thanks to which the recovery time of the ring after a failure does not exceed 50 ms. Using the Loopback Detection (LBD) loop detection function prevents congestion on uncontrolled network segments administered by subscribers or built on the basis of unmanaged switches. In addition, the DGS-3000-28SC switch supports port aggregation functionality based on the 802.1AX standard, the use of which allows you to combine several ports into a group, while increasing bandwidth and increasing fault tolerance of connections to ensure uninterrupted operation and load distribution between multiple network devices.
Triple Play Service
The DGS-3000-28SC switch implements a wide range of multicast functions of level 2, including IGMP/MLD Snooping, Fast Leave and filtering. Support for this functionality provides the opportunity to work with IPTV services, which are gaining popularity and are in increasing demand in the service market every year. The use of host-based IGMP/MLD Snooping functions ensures the connection of several IPTV subscribers to a single network interface. ISM VLAN profiles allow users to quickly and easily assign or replace preset settings for multicast subscriber ports. IGMP Authentication support eliminates the possibility of unauthorized IPTV subscriptions due to the authentication of set-top boxes.
The DGS-3000-28SC switch supports advanced QoS (Quality of Service) functionality to provide quality Triple Play service. Packet classification is based on various header fields or user-defined packet content, providing the possibility of prioritizing traffic. Using the bandwidth management function, providers will be able to determine the bandwidth level of the incoming/outgoing channel for each port in increments of up to 64 Kbit/s.
Easy maintenance, efficient troubleshooting
The support of advanced OAM functionality (Operation, Administration and Management) implemented in the switches makes it possible to significantly simplify maintenance, troubleshooting and troubleshooting. Using the cable diagnostics function, you can remotely monitor the status of the Ethernet cable and determine the location of the fault, which will allow the provider to reduce equipment maintenance costs. The Connectivity Fault Management (CFM, IEEE 802.1ag) function is designed for monitoring, troubleshooting and troubleshooting in End-To-End Ethernet networks, providing providers with the ability to perform connection verification, isolate problematic network segments and identify users of such segments. D-Link Unidirectional Link Detection (DULD) technology allows you to track problems of fiber-optic connection, and thereby increase the stability of the cable infrastructure in MAN (Metropolitan Area Network) networks.
High level of security and operability
The DGS-3000-28SC switch provides advanced user/device authentication functionality, including 802.1X, Web-based access control (WAC) and MAC addresses (MAC). WAC and MAC functions allow network administrators to authenticate a user/device and manage network security without the need to install client software, which is very important if installing software on client hardware is not possible. Also, the DGS-3000-28SC switch supports the functionality of Compound Authentication, providing network administrators with a choice of several authentication methods for one device. Node-based authentication provides precise access control for each device on the network. For integration with billing systems and services, support for RADIUS and TACACS protocols is implemented. The IP-MAC-Port Binding (IMPB) function provided in the DGS-3000-28SC switch provides strict binding by addresses and interfaces, and ARP Spoofing Prevention protects the network from Man–In-The-Middle and ARP Spoofing attacks.
To ensure the smooth operation of the network, the DGS-3000-28SC switch implements the D-Link Safeguard Engine mechanism to protect the CPU from overloading with malicious broadcast traffic caused by viral activity. The switch also supports the DHCP Screening function, which provides filtering of DHCP requests from unauthorized DHCP servers or routers. The use of protection functions against BPDU/DoS attacks and L3 Control Packet Filtering allows you to increase the level of network security.
IPv6 support
The DGS-3000-28SC switch supports IPv6 functionality, including MLD Snooping, WAC, IPv6 ACL/QoS and IMPBv6, which facilitates easy integration of equipment into next-generation networks. In addition, this series supports the functions of both IPv4/v6 protocol stacks, allowing switches to act as a bridge between IPv4 and IPv6 networks.
