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 followed by the new value. For example, to set the IGMP last
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 command by entering:
-> 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.
Modifying the IGMP Query Response Interval
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
how to restore it with the ip multicast query-response-interval command.
Configuring the IGMP Query Response Interval
You can modify the IGMP query response interval from 1 to 65535 in tenths of seconds by entering
ip multicast query-response-interval followed by the new value. For example, to set the IGMP query
response interval to 6000 tenths-of-seconds you would enter:
-> ip multicast query-response-interval 6000
You can also modify the IGMP query response interval on the specified VLAN by entering:
-> ip multicast vlan 3 query-response-interval 6000
