[. . . ] 75 iv About This Guide D-Link Web Smart Switch User Manual About This Guide This guide provides instructions to install the D-Link Fast Ethernet Web Smart Switch DES-1210-28/28P/52, how to use the SmartConsole Utility, and to configure Web-based Management step-by-step. Note: The model you have purchased may appear slightly different from the illustrations shown in the document. Refer to the Product Instruction and Technical Specification sections for detailed information about your switch, its components, network connections, and technical specifications. Getting Started: A startup guide for basic switch installation and settings.

Up to eight Trunk groups may be created, and each group can be consisted of up to eight ports. Select the ports to be grouped together, and then click Apply to activate the selected Trunking groups. Two types of link aggregation can be selected: Static - Static link aggregation. Figure 72 – Configuration > Link Aggregation > Port Trunking NOTE: Each combined trunk port must be connected to devices within the same VLAN group. Configuration > Link Aggregation > LACP Port Settings The LACP Port Settings is used to create port trunking groups on the Switch. The user may set which ports will be active and passive in processing and sending LACP control frames Figure 73 – Configuration > Link Aggregation > LACP Port Settings From Port: The beginning of a consecutive group of ports may be configured starting with the selected port. To Port: The ending of a consecutive group of ports may be configured starting with the selected port. Port Priority (0-65535): Displays the LACP priority value for the port. Activity: There are two different roles of LACP ports: 41 5 Configuration D-Link Web Smart Switch User Manual Active - Active LACP ports are capable of processing and sending LACP control frames. This allows LACP compliant devices to negotiate the aggregated link so the group may be changed dynamically as needs require. In order to utilize the ability to change an aggregated port group, that is, to add or subtract ports from the group, at least one of the participating devices must designate LACP ports as active. Passive - LACP ports that are designated as passive cannot initially send LACP control frames. In order to allow the linked port group to negotiate adjustments and make changes dynamically, one end of the connection must have "active" LACP ports. The possible field values are: Short (3 Sec) - Defines the LACP timeout as 3 seconds. Configuration > IGMP Snooping With Internet Group Management Protocol (IGMP) snooping, the Web Smart Switch can make intelligent multicast forwarding decisions by examining the contents of each frame’s Layer 2 MAC header. With IGMP snooping enabled globally, the Web Smart Switch will forward multicast traffic only to connections that have group members attached. figure 74 – Configuration > IGMP Snooping Configuration By default , IGMP is disabled. If enabled, the IGMP Global Settings will need to be entered: Host Timeout (130-153025 sec): This is the interval after which a learned host port entry will be purged. For each host port learned, a 'Port Purge Timer' runs for 'Host Port Purge Interval'. This timer will be restarted whenever a report message from host is received over that port. [. . . ] And with expected advances in the coming years in silicon technology and digital signal processing that will enable Gigabit Ethernet to eventually operate over unshielded twisted-pair (UTP) cabling, outfitting your network with a powerful 1000-Mbps-capable backbone/server connection which will create a flexible foundation for the next generation of network technology products. Fast Ethernet Technology The growing importance of LANs and the increasing complexity of desktop computing applications are fueling the need for high performance networks. A number of high-speed LAN technologies have been proposed to provide greater bandwidth and improve client/server response times. Among them, 100BASE-T (Fast Ethernet) provides a non-disruptive, smooth evolution from the current 10BASE-T technology. [. . . ]
