xStack® DGS-3120 Series Managed Switch Web UI Reference Guide decides there are no more listeners of a group on a network. Other Querier present interval - Amount of time that must pass before a multicast router decides that there is no longer another multicast router that is the Querier. Last listener query count - Number of group-specific queries sent before the router assumes there are no local listeners of a group. The default number is the value of the robustness variable. By default, the robustness variable is set to 2. You might want to increase this value if you expect a subnet to be loosely. Last Listener Query Interval The maximum amount of time between group-specific query messages, including those sent in response to done-group messages. You might lower this interval to reduce the amount of time it takes a router to detect the loss of the last listener of a group. Data Driven Group Expiry Time Here the user can enter the data driven group expiry time value.

Fast Done Here the user can enable or disable the fast done feature. State Used to enable or disable MLD snooping for the specified VLAN. This field is Disabled by default.
