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
Use the following commands to verify the IGMP snooping configuration.
Command
show ip igmp snooping [[vlan] vlan-id]
show ip igmp snooping groups [[vlan] vlan-id]

Purpose
software assumes that no more than one host is present on
each VLAN port. The default is disabled for all VLANs.
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 an interface belonging to a VLAN as a static
member of a multicast group. You can specify the interface
by type and number.
