DES-3326SR Layer 3 Fast Ethernet Switch CLI Reference Manual config igmp_snooping querier Parameters − The name of the VLAN for which IGMP snooping querier is to be configured. query_interval − Specifies the amount of time in seconds between general query transmissions. the default setting is 125 seconds. max_response_time − Specifies the maximum time in seconds to wait for reports from members. The default setting is 10 seconds. robustness_variable − Provides finetuning to allow for expected packet loss on a subnet. The value of the robustness variable is used in calculating the following IGMP message intervals: • Group member interval- Amount of time that must pass before a multicast router decides there are no more members of a group on a network. This interval is calculated as follows: (robustness variable x query interval) + (1 x query response interval). • 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. This interval is calculated as follows: (robustness variable x query interval) + (0.5 x query response interval). IGMP Snooping Commands 243
