If IGMP is disabled on an interface, the IGMP parameters on the interface return to the
default values.
Example
The following example configures the frequency at which the software sends IGMP host query
messages on port g5 to 600 seconds.
Console (config)# interface ethernet g5
Console (config-if)# ip igmp query-interval 600
ip igmp last-member-query-interval
The ip igmp last-member-query-interval interface configuration command configures the
frequency at which the software sends Internet Group Management Protocol (IGMP) group-
specific host query messages. To set this frequency to the default value, use the no form of this
command.
