[. . . ] ExtensiveLayer2Features Implemented as complete L2 feature, these switches include features such as IGMP snooping, port mirroring, Spanning Tree and port trunks. The IEEE 802. 3xflowcontrolfunctionallowsyourserversto directly connect to the switch for fast, reliable data transfer. At2000Mbpsfullduplex, thegigabitports provide high-speed data pipes to your servers with minimum data transfer loss. QoS, 802. 1QVLANandAsymmetricVLAN Theswitchessupport802. 1QVLANstandardtagging by prioritizing traffic to enhance network security and performance. Also support 802. 1p priority queues, enabling users to run bandwidth-sensitive applicationssuchasstreamingmultimediaandVoIP in network. These functions allow switches to work seamlesslywithVLANand802. 1ptrafficinnetwork. AsymmetricVLANisimplementedintheseswitches for a more efficient use of shared resources such as server or gateway devices. SecureyourNetwork D-Link's innovative Safeguard Engine function protects the switches against traffic flooding caused by virus attacks. They support 802. 1X port-based authentication, allowing network to be configured with external RADIUSservers. VersatileManagement The new generation of web smart switches provides growing businesses simple and easy management of their network using an intuitive SmartConsole utility or a Web-Based management interface that allows administrators to remotely control their network down to the port level. The SmartConsole easily allows customers to discover multiple DLink web smart switches with the same L2 network segment connected to user's local PC. With this utility, users do not need to change the IP address of PC and also provides easy initial setting of smart switches. The switches with the same L2 network segment connected to user's local PC are displayed on the screen for instant access.
