xStack® DES-3528/DES-3552 Series Layer 2 Stackable Fast Ethernet Managed Switch Web UI Reference Guide Max Response Time (1- The maximum time in seconds to wait for reports from listeners. The default setting is 25) 10 seconds. Robustness Value (1-7) Provides fine-tuning to allow for expected packet loss on a subnet. The value of the robustness variable is used in calculating the following MLD message intervals: Group listener interval - Amount of time that must pass before a multicast router 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 (1-25) 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 (1-65535) Enter the data driven group expiry time value. Querier State This allows the Switch to be specified as an MLD Querier (sends MLD query packets) or a Non-Querier (does not send MLD query packets). Set to enable or disable. Fast Done 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. Report Suppression Enable or disable the report suppression features. Data Driven Learning State Enable or disable data driven learning of MLD snooping groups. Data Driven Learning Aged Out Enable or disable the age out function for data driven entries. Version Specify the version of MLD packet that will be sent by this port.
