Description

• D-Link green

  D-Link is constantly striving to take the lead in developing innovative technology that allows for power-saving while not sacrificing operational performance or functionality. Power saving by link status helps to further save energy by automatically switching ports without a link to sleep mode and thus drastically reducing power consumption. The DGS-1210 series takes the approach to green IT and power saving one step further by incorporating a special chipset with Silicon technology.

• Seamless integration

  The DGS-1210 series comes with Ethernet and Gigabit copper ports capable of connecting to existing Cat.5 twisted-pair cables. Additionally, the four ports of the DGS-1210 series combine SFP and copper connectivity into one port and therefore provide a more flexible solution for upstream or downstream server connections via fiber interface. Using the default presets, the administrator can quickly set up the switch without worrying about reconfiguring any settings and providing easy access for the user.

• 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 2000Mbps 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. Cable diagnostics is designed for network administrators to quickly examine the quality of the copper cables and also determine the type of cable error.

• 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 application. 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, the network administrator 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 function 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 on a LAN, 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.
