DES-1100 Series Easy Smart Swtiches Green Technology Fanless Design Advanced Features Intuitive Management VLAN Features Advanced QoS D-Link DES-1100-16/24 is the latest series of EasySmart Switches. Equipped with 16 or 24 10/100 Mbps ports, the series integrates basic configurable functions that provide performance and scalability. With easy to use management interface via PC Utility or Web Browser, these EasySmart series help customers to quickly and easily deploy their network. The DES-1100 Series provides a complete and affordable solution for Small and Medium Business or communities without IT staff. They are suitable for Enterprise deployment, such as branch offices and meeting rooms that require simple management. Management options for the switches include Web Management and SmartConsole Utility. The series also supports Layer 2 features such as Port Mirroring, Statistics and IGMP Snooping to optimize performance for multicast applications. Both models come with an innovative fanless design in compact 11"metal cases. Equipped with a complete lineup of L2 features, these switches include IGMP Snooping and Port Mirroring. Network maintenance features include Loopback Detection and Cable Diagnostics. Loopback Detection is used to detect loops created by a specific port and automatically shuts 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. For Quality of Service (QoS), the switches support 802.1p. This standard is a mechanism that allows real-time traffic classification into 8 priority levels mapped to 4 queues. The DES-1100 series supports 802.1Q VLAN and Portbased VLAN, for traffic segregation. The bandwidth control feature allows network administrators to define the throughput levels for each port in order to manage bandwidth. It also provides fine granularity to define the ingress/egress traffic limits down to 512 kbps segments. The Storm Control feature allows detection when broadcast, multicast or unknown unicast traffic hit the definable threshold. The switch will start blocking or discarding packets which would otherwise ‘flood' the network. The blocked port will be activated only when the broadcast or multicast traffic falls below the defined threshold. Port Mirroring helps administrators facilitate traffic diagnostics or track switch performance and alter when necessary.
