The robustnessis the tuning for the expected packet loss on a subnet. If a subnet is expected to have a lot of loss, therobustness variable may be increased for the interface or VLAN.Syntax ip igmp robustness robustnessThe range for robustness is 1 to 255.The no ip igmp robustness command sets the robustness value to the default.Default 2Mode Interface Config; Interface VLANCommandHistoryip igmp startup-query-countThis command sets the number of Queries sent out on startup, separated by the Startup Query Intervalon the interface or VLAN.Syntax ip igmp startup-query-count countVersion 2.3 Modified: Added Interface VLAN mode.Parameters 0-255 Specify the maximum response time interval in tenths of a second.Range: 0 to 255 tenths of a secondVersion 2.3 Modified: Changed from ip igmp query-max-response-time to ip igmpquery-max-resp-time and added Interface VLAN mode.Version 2.3 Modified: Added Interface VLAN mode.
