Syntax
ip igmp last-member-query-interval seconds

source-specific queries upon receipt of a leave message. (Range: 1-255
tenths of a second)
Default Setting

Command Usage
When the switch receives an IGMPv2 or IGMPv3 leave message from a host that
wants to leave a multicast group, source or channel, it sends a number of group-
specific or group-source-specific query messages at intervals defined by this
command. If no response is received after this period, the switch stops forwarding
for the group, source or channel.
Example
Console(config)#interface vlan 1
Console(config-if)#ip igmp last-member-query-interval 20
Console(config-if)#
