Configuring the IGMP Last Member Query Interval

You can modify the IGMP last member query interval from 1 to 65535 in tenths of seconds by entering
ip multicast last-member-query-interval
member query interval to 60 tenths-of-seconds on the system if no VLAN is specified, you would enter:
-> ip multicast last-member-query-interval 60
You can also modify the IGMP last member query interval on the specified VLAN by entering:
-> ip multicast vlan 3 last-member-query-interval 60

Restoring the IGMP Last Member Query Interval

To restore the IGMP last member query interval to its default (i.e., 10 tenths-of-seconds) value on the
system if no VLAN is specified, use the
-> ip multicast last-member-query-interval 0
Or, as an alternative, enter:
-> ip multicast last-member-query-interval
To restore the IGMP last member query interval to its default value.
You can also restore the IGMP last member query interval on the specified VLAN by entering:
-> ip multicast vlan 2 last-member-query-interval 0
Or, as an alternative, enter:
-> ip multicast vlan 2 last-member-query-interval
To restore the IGMP last member query interval to its default value.

The default IGMP query response interval (i.e., the time period to reply to an IGMP query message) is 100
in tenths of seconds. The following subsections describe how to configure the query response interval and
