The DGS-1210 Series includes a wide range of port and media types, including 10/100/1000BASE-T RJ-45 ports, 100/1000 Mbps combo ports, and 100/1000 Mbps SFP ports, allowing you to choose the most suitable media type for your requirements. The DGS-1210-28 switch comes with 28 Gigabit copper ports capable of connecting to existing Cat.5 (or higher) twisted-pair cables. Additionally, the last 4 ports of the DGS-1210-28 offer either RJ45 or SFP connectivity and therefore provide an option for upstream or downstream server connections via fibre interface. Using the default presets, the administrator can quickly set up the switch without reconfiguring any settings.
Extensive Layer 2 Features
Equipped with a complete lineup of L2 features, the DGS-1210-28 includes IGMP Snooping, Port Mirroring, Rapid Spanning Tree and Link Aggregation Control Protocol (LACP). The IEEE 802.3x Flow Control function allows servers to directly connect to the switch for fast, reliable data transfer. At 2000 Mbps Full Duplex, the Gigabit ports provide high-speed data pipes to servers with minimum data transfer loss. Network maintenance features include Loopback Detection and Cable Diagnostics. Loopback Detection is used to detect loops created by a specific port and automatically shut down the affected port. The Cable Diagnostic feature, designed primarily for administrators and customer service representatives, can rapidly discover the type of error and determine the cable quality.
QoS, Bandwidth Control
The DGS-1210-28 is perfect for deployment in a VoIP environment, as it support Auto Voice VLAN and Differentiated Services Code Point (DSCP) QoS for VoIP. Auto Voice VLAN will automatically place voice traffic from an IP phone to an assigned VLAN and by doing so enhance the VoIP service. With a higher priority and individual VLAN, this feature guarantees the quality and security of VoIP traffic. DSCP marks parts of an IP packet, enabling different levels of service to be assigned for network traffic. With Bandwidth Control, network administrators can reserve bandwidth for important functions that require a larger bandwidth or might have high priority.
Secure your Network
D-Link’s innovative Safeguard Engine protects the switches against traffic flooding caused by virus attacks. The switches also support 802.1x port-based authentication, allowing the network users to be authenticated through external RADIUS servers. In addition, the Access Control List (ACL) feature enhances network security and helps to protect the internal IT network. The DGS-1210-28 switch includes ARP Spoofing Prevention, which protects from attacks on the Ethernet network that may allow an intruder to sniff data frames, modify traffic, or bring traffic to a halt altogether by sending fake ARPmessages to the network. To prevent ARP Spoofing attacks, the switch uses Packet Control ACLs to block invalid packets that contain fake ARP messages. For added security, the DHCP Server Screening feature screens rogue DHCP server packets from user ports to prevent unauthorized IP assignment.
The DGS-1210-28 provides a SmartConsole utility and a web-based management interface that enables administrators to remotely control their network down to the port level. The SmartConsole easily allows customers to discover multiple D-Link Web Smart Switches within the same L2 network segment. With this utility, users do not need to change the IP address of their PC. It also simplifies the initial setup of the WebSmart Switches. The DGS-1210-28 also supports D-View and Compact Command Line Interface (CLI) through Telnet. D-View is a Network Management System that allows for the central management of critical network characteristics such as availability, reliability, resilience, and security. CLI management of the switches is possible via Telnet. This makes it possible to adjust basic settings, passwords, configuration files, and firmware with ease.
