Configuring IGMP Snooping Parameters

To manage the operation of the IGMP snooping process, you can configure the optional IGMP snooping parameters described in the following table.

Table 11: IGMP Snooping Parameters
Parameter	Description
IGMP snooping	Enables IGMP snooping on a per-VLAN basis. The
	default is enabled.
	Note	If the global setting is disabled, then all
		VLANs are treated as disabled, whether they
		are enabled or not.
Explicit tracking	Tracks IGMPv3 membership reports from individual
	hosts for each port on a per-VLAN basis. The default
	is enabled.
Fast leave	Enables the software to remove the group state when
	it receives an IGMP Leave report without sending an
	IGMP query message. This parameter is used for
	IGMPv2 hosts when no more than one host is present
	on each VLAN port. The default is disabled.
Last member query interval	Sets the interval that the software waits after sending
	an IGMP query to verify that no hosts that want to
	receive a particular multicast group remain on a
	network segment. If no hosts respond before the last
	member query interval expires, the software removes
	the group from the associated VLAN port. Values
	range from 1 to 25 seconds. The default is 1 second.
Snooping querier	Configures a snooping querier on an interface when
	there is no multicast router in the VLAN to generate
	queries. The default is disabled.
Report suppression	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.
Multicast router	Configures a static connection to a multicast router.
	The interface to the router must be in the selected
	VLAN.
