The lastmember-queryinterval command globally sets the interval for the IGMP querier to send IGMP group-specific query messages after the interface receives an IGMP Leave message from a host.
The undo lastmember-queryinterval command restores the default configuration.
| Parameter | Description | Value |
|---|---|---|
| interval | Specifies the interval for the IGMP querier to send group-specific query messages after the interface receives a Leave message from a host. | The value ranges from 1 to 5, in seconds. By default, the value is 1. |
In IGMPv3, this command can also be used to set the interval for an IGMP querier to send group/source-specific messages after receiving the Report message about the change of the relationship between the multicast group and its source list.
The function of this command is the same as that of the igmp lastmember-queryinterval command used in the interface view, except for the function range. The configuration in the IGMP view is globally valid in the instance, whereas the configuration in the interface view is valid only for the current interface. The system prefers the configuration in the system view. The configuration in the IGMP view is used only when the configuration in the interface view is not done.
