User Guidelines
Use the ip igmp query-interval command to configure the frequency at
which the IGMP querier sends IGMP host-query messages from an interface.
The IGMP querier sends query-host messages to discover which multicast
groups have members on the attached networks of the router.
The query interval must be bigger than the maximum query response time.
Example
The following example shows how to increase the frequency at which the
IGMP querier sends IGMP host-query messages to 180 seconds:
console(config)#
interface vlan 100
console(config-if)#
ip igmp query-interval 180
console(config-if)#
exit
