ip igmp snooping leave-time-out
The ip igmp snooping leave-time-out command configures the leave-time-out. If an IGMP report
for a Multicast group is not received within the leave-time-out period after an IGMP leave was
received from a specific port, the current port is deleted from the member list of that Multicast
group. To configure the default leave-time-out, use the
no form of this command.
