A multicast router periodically sends IGMP general query messages onto the attached subnets to 

determine whether multicast group members are present on the subnets. The IGMP query interval can 

be tuned according to the practical conditions of the network. 

Related commands: igmp timer other-querier-present. 

# Set the IGMP query interval to 150 seconds on VLAN-interface 2.

Interface view 

1: Specifies IGMP version 1. 

2: Specifies IGMP version 2. 

Use the igmp version command to specify the version of IGMP to run on the interface.  

Use the undo igmp version command to restore the default. 

The default IGMP version is IGMP version 2.  

The device cannot automatically switch between different IGMP versions, so all the devices on a subnet 

must run the same version of IGMP.  

# Run IGMPv1 on VLAN-interface 10.
