xStack® DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch 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. Both devices must support LACP. 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 (see above). After setting the previous parameters, click Apply to allow your changes to be implemented. The LACP Port Information table on the LACP Port Settings window displays which ports are active and passive. IGMP Snooping Internet Group Management Protocol (IGMP) snooping allows the Switch to recognize IGMP queries and reports sent between network stations or devices and an IGMP host. When enabled for IGMP snooping, the Switch can open or close a port to a specific device based on IGMP messages passing through the Switch. In order to use IGMP Snooping it must first be enabled for the entire Switch (see the Device Information window that opens when clicking the Web Management Tool at the top of the Web Manager menu in the left pane). Users may then fine-tune the settings for each VLAN using the IGMP Snooping Settings folder under L2 Features. When enabled for IGMP snooping, the Switch can open or close a port to a specific multicast group member based on IGMP messages sent from the device to the IGMP host or vice versa. The Switch monitors IGMP messages and discontinues forwarding multicast packets when there are no longer hosts requesting that they continue. IGMP Snooping Settings This window is used to Enable, Disable or Modify the IGMP Snooping Settings on the Switch. To view this window, click L2 Features > IGMP Snooping > IGMP Snooping Settings, as shown below. Figure 3 - 28 IGMP Multicast Router Only Settings window The following parameters can be configured: Parameter Description IGMP Multicast Router Only Use the pull-down menu to enable or disable the IGMP multicast router.
