Description :    The switches provide MAC address filters screen access to the network. They support 802.1x port-based authentication, allowing the network to be configured with external RADIUS servers. Additional features like D-Link Safeguard Engine protect the switches against traffic flooding caused by virus/worm outbreaks. With full colour graphic pictures, diagrams, and easy to understand navigation menus, the switches' Web based SmartConsole Utility is as easy to use as surfing the net. It includes useful features like auto-discovery for automatic display of all DES-1228 and DES-1252 switches running on the network, Monitor List for status and trap messages and Trap View for system events, device boot up, abnormal data transfer errors and illegal login. With built-in SNMP-based MIBs, the switches can also be integrated in an SNMP-based network and polled to provide valuable information about the status of the unit and send traps on abnormal events.
