Information
ip igmp snooping last-member-query-interval
Queriers normally send a certain number of queries when a leave message is received prior to
deleting a group from the membership database. There may be situations in which fast
deletion of a group is required. When IGMP fast leave processing is enabled, the switch will
remove an interface from the multicast group as soon as it detects an IGMP version 2 leave
message on the interface.
ip igmp snooping last-member-query-interval
c e s The last member query interval is the “maximum response time” inserted into Group-Specific
queries sent in response to Group-Leave messages. This interval is also the interval between
successive Group-Specific Query messages. Use this command to change the last member
query interval.
