Interval

To support existing configurations and for maximum flexibility, you can manually override the Default Timeout Interval. We do not recommend this.

Manager Switch 1> set ip igmp timeout=180

Warning (2005430): The Default Timeout Interval is below the default safe value of (Default Query Interval * Robustness ) + (Query Response Interval / 10).
