DESCRIPTION
"The version of MLD which is running on this interface.
This object is a place holder to allow for new versions
of MLD to be introduced. Version 1 of MLD is defined
in RFC 2710."
DEFVAL { 1 }
::= { mldInterfaceEntry 4 }
mldInterfaceQuerier OBJECT-TYPE

::= { mldInterfaceEntry 6 }
mldInterfaceJoins 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

::= { mldInterfaceEntry 8 }
mldInterfaceRobustness OBJECT-TYPE
SYNTAX Unsigned32
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. MLD is
robust to (Robustness Variable-1) packet losses. The
discussion of the Robustness Variable is in Section 7.1
of RFC 2710."
DEFVAL { 2 }
::= { mldInterfaceEntry 9 }
mldInterfaceLastListenQueryIntvl OBJECT-TYPE
SYNTAX Unsigned32
UNITS "seconds"
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The Last Member Query Interval is the Max Response
Delay 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."
DEFVAL { 1 }
::= { mldInterfaceEntry 10 }
mldInterfaceProxyIfIndex OBJECT-TYPE
SYNTAX InterfaceIndexOrZero
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"Some devices implement a form of MLD proxying whereby
memberships learned on the interface represented by this
row, cause MLD Multicast Listener Reports to be sent on
the internetwork-layer interface identified by this
object. Such a device would implement mldRouterMIBGroup
only on its router interfaces (those interfaces with
non-zero mldInterfaceProxyIfIndex). Typically, the
value of this object is 0, indicating that no proxying
is being done."
DEFVAL { 0 }
::= { mldInterfaceEntry 11 }

DESCRIPTION
"The time remaining before the Other Querier Present
Timer expires. If the local system is the querier,
the value of this object is zero."

contains information for an IPv6 multicast group
address."

MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The time elapsed since this entry was created."
::= { mldCacheEntry 5 }
mldCacheExpiryTime 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 mldCacheSelf 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."
