This example shows how to configure IGMP snooping parameters for a VLAN:
switch# configure terminal
switch(config)# vlan configuration 5
switch(config-vlan)# ip igmp snooping last-member-query-interval 3
switch(config-vlan)# ip igmp snooping querier 172.20.52.106
switch(config-vlan)# ip igmp snooping explicit-tracking
switch(config-vlan)# ip igmp snooping fast-leave
switch(config-vlan)# ip igmp snooping report-suppression
switch(config-vlan)# ip igmp snooping mrouter interface ethernet 1/10
switch(config-vlan)# ip igmp snooping static-group 230.0.0.1 interface ethernet 1/10
switch(config-vlan)# end
Verifying the IGMP Snooping Configuration

Purpose
Removes the group from the associated VLAN port if no hosts
respond to an IGMP query message before the last member
query interval expires. Values range from 1 to 25 seconds.
The default is 1 second.
Configures a snooping querier when you do not enable PIM
because multicast traffic does not need to be routed. The IP
address is used as the source in messages. The default is
disabled.
Limits the membership report traffic sent to multicast-capable
routers. When you disable report suppression, all IGMP
reports are sent as is to multicast-capable routers. The default
is enabled.
Configures a static connection to a multicast router. The
interface to the router must be in the selected VLAN. You
can specify the interface by type and number.
Configures a static connection to a virtual port channel (vPC)
peer link. By default, the vPC peer link is considered as a
multicast router port and the multicast packet is sent to the
peer link for each receiver VLAN. To send the multicast traffic
over a vPC peer link to each receiver VLAN that has orphan
ports, use the no ip igmp snooping mrouter vpc-peer-link
command. The IGMP snooping mrouter VPC peer link should
also be globally disabled on the peer VPC switch.
Configures an interface belonging to a VLAN as a static
member of a multicast group. You can specify the interface
by type and number.
