enabled."
::= { igmpInterfaceEntry 1 }
igmpInterfaceQueryInterval OBJECT-TYPE
SYNTAX Unsigned32

transmitted on this interface."
DEFVAL { 125 }
::= { igmpInterfaceEntry 2 }
igmpInterfaceStatus OBJECT-TYPE
SYNTAX RowStatus
MAX-ACCESS read-create

DESCRIPTION
"The activation of a row enables IGMP on the interface. The
destruction of a row disables IGMP on the interface."
::= { igmpInterfaceEntry 3 }
igmpInterfaceVersion OBJECT-TYPE
SYNTAX Unsigned32
MAX-ACCESS read-create
STATUS current
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
routers on a LAN must be configured to run the same version
of IGMP on that LAN."
DEFVAL { 2 }
::= { igmpInterfaceEntry 4 }

SYNTAX IpAddress
MAX-ACCESS read-only

DESCRIPTION
"The address of the IGMP Querier on the IP subnet to which
this interface is attached."
::= { igmpInterfaceEntry 5 }
igmpInterfaceQueryMaxResponseTime OBJECT-TYPE
SYNTAX Unsigned32 (0..255)
UNITS "tenths of seconds"
MAX-ACCESS read-create

igmpInterfaceQuerierExpiryTime OBJECT-TYPE
SYNTAX TimeTicks
MAX-ACCESS read-only

DESCRIPTION
"The amount of time remaining before the Other Querier

igmpInterfaceVersion1QuerierTimer OBJECT-TYPE
SYNTAX TimeTicks
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The time remaining until the host assumes that there are no
IGMPv1 routers present on the interface. While this is non-
zero, the host will reply to all queries with version 1
membership reports."
::= { igmpInterfaceEntry 9 }
igmpInterfaceWrongVersionQueries OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The number of queries received whose IGMP version does not
match igmpInterfaceVersion, over the lifetime of the row
entry. 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."
::= { igmpInterfaceEntry 10 }
igmpInterfaceJoins OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The number of times a group membership has been added on
this interface; that is, the number of times an entry for
this interface has been added to the Cache Table. This
object gives an indication of the amount of IGMP activity
over the lifetime of the row entry."
::= { igmpInterfaceEntry 11 }
igmpInterfaceProxyIfIndex OBJECT-TYPE
SYNTAX InterfaceIndexOrZero
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"Some devices implement a form of IGMP proxying whereby
memberships learned on the interface represented by this
row, cause IGMP Host Membership Reports to be sent on the
interface whose ifIndex value is given by this object. Such
a device would implement the igmpV2RouterMIBGroup only on
its router interfaces (those interfaces with non-zero
igmpInterfaceProxyIfIndex). Typically, the value of this
object is 0, indicating that no proxying is being done."
DEFVAL { 0 }
::= { igmpInterfaceEntry 12 }

SYNTAX Gauge32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The current number of entries for this interface in the
Cache Table."
::= { igmpInterfaceEntry 13 }
igmpInterfaceRobustness OBJECT-TYPE
SYNTAX Unsigned32 (1..255)
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The Robustness Variable allows tuning for the expected
packet loss on a subnet. If a subnet is expected to be
lossy, the Robustness Variable may be increased. IGMP is
robust to (Robustness Variable-1) packet losses."
DEFVAL { 2 }
::= { igmpInterfaceEntry 14 }
igmpInterfaceLastMembQueryIntvl OBJECT-TYPE
SYNTAX Unsigned32 (0..255)
UNITS "tenths of seconds"
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The Last Member Query Interval is the Max Response Time
inserted into Group-Specific Queries sent in response to
Leave Group messages, and is also the amount of time between
Group-Specific Query messages. This value may be tuned to
modify the leave latency of the network. A reduced value
results in reduced time to detect the loss of the last
member of a group. The value of this object is irrelevant
if igmpInterfaceVersion is 1."

this group address on this interface."

igmpCacheLastReporter OBJECT-TYPE
SYNTAX IpAddress
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The IP address of the source of the last membership report
received for this IP Multicast group address on this
interface. If no membership report has been received, this
object has the value 0.0.0.0."
::= { igmpCacheEntry 4 }
igmpCacheUpTime OBJECT-TYPE
SYNTAX TimeTicks
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The time elapsed since this entry was created."
::= { igmpCacheEntry 5 }
igmpCacheExpiryTime OBJECT-TYPE
SYNTAX TimeTicks
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The minimum amount of time remaining before this entry will
be aged out. A value of 0 indicates that the entry is only
present because igmpCacheSelf is true and that if the router
left the group, this entry would be aged out immediately.
Note that some implementations may process membership
reports from the local system in the same way as reports
from other hosts, so a value of 0 is not required."
::= { igmpCacheEntry 6 }
igmpCacheStatus OBJECT-TYPE
SYNTAX RowStatus
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The status of this entry."
::= { igmpCacheEntry 7 }
igmpCacheVersion1HostTimer OBJECT-TYPE
SYNTAX TimeTicks
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The time remaining until the local router will assume that
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."
