Interval
To support existing configurations and for maximum flexibility, you can manually override the
Default Timeout Interval. We do not recommend this.
The warning message also displays when the router or switch starts up and in the log file, as
the following output shows.
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).
