	STATUS mandatory
	DESCRIPTION "The version of IGMP which is running on this interface.
This object can be used to configure a router capable of
running either value.  For IGMP to function correctly, all

igmpInterfaceQuerierPresentTimeout OBJECT-TYPE
	SYNTAX INTEGER

	DESCRIPTION "A timeout interval.  If no IGMPv2 queries are heard on this
interface within this timeout interval, the local router
will take over the Querier on the IP subnet to which this
interface is attached.  This object is now deprecated,
since its value can be derived from 
igmpInterfaceRobustness."

igmpInterfaceLeaveEnabled OBJECT-TYPE
	SYNTAX TruthValue
	ACCESS read-only
	STATUS optional
	DESCRIPTION "An indication of whether the processing of IGMPv2 Leave
messages is enabled on this interface.  This object is
now deprecated since it must be true when
igmpInterfaceVersion is version2, and must be false when
it is version1 to comply with the IGMP specfication."

igmpInterfaceVersion1QuerierTimer OBJECT-TYPE
	SYNTAX INTEGER
	ACCESS read-only
	STATUS mandatory

IGMPv1 routers present on the interface.  While this is
non-zero, the host will reply to all queries with version 1
membership reports."

igmpInterfaceWrongVersionQueries OBJECT-TYPE
	SYNTAX Counter
	ACCESS read-only
	STATUS mandatory
	DESCRIPTION "The number of queries received whose IGMP version does not
match igmpInterfaceVersion.  IGMP requires that all routers
on a LAN be configured to run the same version of IGMP.
Thus, if any queries are received with the wrong version,
this indicates a configuration error."

object gives an indication of the amount of IGMP activity
over time."

igmpInterfaceLeaves OBJECT-TYPE
	SYNTAX Counter
	ACCESS read-only
	STATUS optional
	DESCRIPTION "The number of times a group membership has been removed
from this interface; that is, the number of times an entry
for this interface has been deleted from the Cache Table.
This object is deprecated since its value cannot be
usefully compared with igmpInterfaceJoins to get the
number of groups joined.  Instead, igmpInterfaceGroups
gives the number of groups joined, which may be compared
with igmpInterfaceJoins to derive the number of leaves."
	::= { igmpInterfaceEntry 12 }


igmpInterfaceGroups OBJECT-TYPE
	SYNTAX Gauge
	ACCESS read-only

there are no longer any IGMP version 1 members on the IP
subnet attached to this interface.  Upon hearing any IGMPv1
Membership Report, this value is reset to the group
membership timer.  While this time remaining is non-zero,
the local router ignores any IGMPv2 Leave messages for this
group that it receives on this interface."
