User Guidelines
The last-member-query-interval is the amount of time in seconds after which
a host is considered to have left the group. This value must be less than the
IGMP Query Interval time value. The range is 1 to 25 seconds. The no form
of this command sets the last-member-query-interval on the VLAN to the
default value. When using IGMP Snooping Querier, this parameter should be
less than the value for the IGMP Snooping Querier query interval.
Example
The following example sets the maximum response time to 7 seconds on
VLAN 2.
console(config)#ip igmp snooping vlan 2 last-member-query-interval 7
