This command suppresses general queries except for ports attached to
downstream multicast hosts. Use the no form to flood general queries to all ports
except for the multicast router port.

Command Usage
By default, general query messages are flooded to all ports, except for the
multicast router through which they are received.
If general query suppression is enabled, then these messages are forwarded
only to downstream ports which have joined a multicast service.
Example
Console(config)#ip igmp snooping vlan 1 general-query-suppression
Console(config)#
ip igmp snooping vlan
immediate-leave
This command immediately deletes a member port of a multicast service if a leave
packet is received at that port and immediate-leave is enabled for the parent VLAN.
Use the no form to restore the default.
Syntax
ip igmp snooping vlan vlan-id immediate-leave [by-host-ip]
no ip igmp snooping vlan vlan-id immediate-leave
vlan-id - VLAN ID (Range: 1-4094)

there are no hosts joining this group.
