—Frequency, in seconds, at which the switch sends IGMP query
messages from the interface. The range is from 30 to 18000.

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:
switchxxxxxx(config)# interface vlan 100
switchxxxxxx(config-if)# ip igmp query-interval 180
switchxxxxxx(config-if)# exit
21.5 ip igmp query-max-response-time
To configure the maximum response time advertised in Internet Group
Management Protocol (IGMP) queries, use the ip igmp query-max-response-time
command in Interface Configuration mode. To restore the default value, use the no
form of this command.
