Product Introduction D-Link Web Smart Switch User Manual441 Product IntroductionThank you and congratulations on your purchase of D-Link Web Smart Switch Products.D-Link's next generation Web Smart Ethernet switch series blends plug-and-play simplicity with exceptionalvalue and reliability for small and medium-sized business (SMB) networking. All models are housed in a newstyle rack-mount metal case with easy-to-view front panel diagnostic LEDs, and provides advanced featuresincluding network security, traffic segmentation, QoS and versatile management.Flexible Port Configurations. The DGS-1210 series is the new generation of Web Smart series. It providesa variety of port counts- 16 or 24 10/100/1000Mbps ports plus 4 SFP ports, or 44 10/100/1000Mbps portsplus 4 Combo Copper/SFP ports.D-Link Green Technology. D-Link Green devices are about providing eco-friendly alternatives withoutcompromising performance. D-Link Green Technology includes a number of innovations to reduce energyconsumption on DGS-1210 series such as shutting down a port, or turning off some LED indicators, oradjusting the power usage according to the Ethernet cable connected to it.Extensive Layer 2 Features. Implemented as complete L2 devices, these switches include functions suchas IGMP snooping, port mirroring, Spanning Tree, 802.3ad LACP and Loopback Detection to enhanceperformance and network resiliency.Traffic Segmentation, QoS and Auto Surveillance VLAN. The switches support 802.1Q VLAN standardtagging to enhance network security and performance. The switches also support 802.1p priority queues,enabling users to run bandwidth-sensitive applications such as streaming multimedia by prioritizing thattraffic in network. These functions allow switches to work seamlessly with VLAN and 802.1p traffic in thenetwork. Auto Surveillance VLAN will automatically place the video traffic from pre-defined IP surveillancedevices to an assigned VLAN with higher priority, so it can be separated from normal data traffic. AsymmetricVLAN is implemented in these switches for a more efficient use of shared resources, such as server orgateway devices.Network Security. D-Link’s innovative Safeguard Engine function protects the switches against trafficflooding caused by virus attacks. Additional features like 802.1X port-based authentication provide accesscontrol of the network with external RADIUS servers. ACL is a powerful tool to screen unwanted IP or MACtraffic. Storm Control can help to keep the network from being overwhelmed by abnormal traffic. PortSecurity is another simple but useful authentication method to maintain the network device integrity.Versatile Management. The new generation of D-Link Web Smart Switches provides growing businesseswith a simple and easy management of their network, using a Web-Based management interface that allowsadministrators to remotely control their network down to the port level.Users can also access the switch via TELNET. Some basic tasks can be performed such as changing theSwitch IP address, resetting the settings to factory defaults, setting the administrator password, rebooting theSwitch, or upgrading the Switch firmware by using the Command Line Interface (CLI).In addition, users can utilize the SNMP MIB (Management Information Base) to poll the switches forinformation about the status, or send out traps of abnormal events. SNMP support allows users to integratethe switches with other third-party devices for management in an SNMP-enabled environment
