You can modify the IGMP last member query interval from 1 to 65535 in tenths of seconds by entering 

 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

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 

 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.

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 

 command.

You can modify the IGMP query response interval from 1 to 65535 in tenths of seconds by entering 

 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
