产品功能

• D-Link Green
  D-Link is constantly striving to take the lead in developing innovative technology that allows for power-saving without sacrificing operational performance or functionality. The DGS-1210 series automatically detects the length of connected cables and can adjust power usage by saving energy on shorter cable connections of up to 20 meters. Link status drastically reduces power consumption by automatically toggling ports without a link to sleep mode. The DGS-1210 series takes the approach to green IT one step further by incorporating a special chipset with advanced silicon technology.
• Extensive Layer 2 features
  Equipped with a complete lineup of L2 features, these switches include IGMP Snooping, Port Mirroring, 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 switches are perfect for deployment in a VoIP environment, as they 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 safeguard engine protects the switches against traffic flooding caused by virus attacks. The switches also support 802.1x port-based authentication, allowing the network 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 series 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 ARP messages 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.
• Versatile management
  The DGS-1210 series 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 smart switches. Switches within the same L2 network segment that are connected to the user's PC are displayed on screen for instant access. This allows extensive switch configuration and basic setup of discovered devices including password changes and firmware upgrades.
