•
Query Interval (1 to 60) – Enter a value, in seconds. The default is 1 second. This is the
interval between general queries sent by the unit. By varying the query interval, the
administrator may tune the number of IGMP messages on the subnet; note that larger
numbers cause the IGMP queries to be sent less often.
•
Query Response Interval (1 to 25) – This is the maximum response time inserted into the
periodic general queries. By varying the Query Response Interval, the administrator may
tune the "burstiness" of IGMP messages on the subnet; note that larger values make the
traffic less "bursty" as host responses are spread out over a large interval.
The number of seconds assigned to the Query Response Interval must be less
than the Query Interval.
