DEFVAL { 125 } ::= { mldInterfaceEntry 2 } mldInterfaceStatus OBJECT-TYPE SYNTAX RowStatus MAX-ACCESS read-create STATUS current DESCRIPTION "The activation of a row enables MLD on the interface. The destruction of a row disables MLD on the interface." ::= { mldInterfaceEntry 3 } mldInterfaceVersion OBJECT-TYPE SYNTAX Unsigned32 MAX-ACCESS read-create STATUS current 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 SYNTAX InetAddressIPv6 (SIZE (16)) MAX-ACCESS read-only STATUS current DESCRIPTION "The address of the MLD Querier on the IPv6 subnet to which this interface is attached." ::= { mldInterfaceEntry 5 } mldInterfaceQueryMaxResponseDelay OBJECT-TYPE SYNTAX Unsigned32 UNITS "seconds" MAX-ACCESS read-create STATUS current DESCRIPTION "The maximum query response time advertised in MLD queries on this interface." DEFVAL { 10 } ::= { 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.

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 { true } ::= { mldCacheEntry 3 } mldCacheLastReporter OBJECT-TYPE SYNTAX InetAddressIPv6 (SIZE (16)) MAX-ACCESS read-only STATUS current DESCRIPTION "The IPv6 address of the source of the last membership report received for this IPv6 Multicast group address on this interface. If no membership report has been received, this object has the value 0::0." ::= { mldCacheEntry 4 } mldCacheUpTime OBJECT-TYPE SYNTAX TimeTicks 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." ::= { mldCacheEntry 6 } mldCacheStatus OBJECT-TYPE SYNTAX RowStatus MAX-ACCESS read-create STATUS current DESCRIPTION "The status of this row, by which new entries may be created, or existing entries deleted from this table." ::= { mldCacheEntry 7 } -- conformance information mldMIBConformance OBJECT IDENTIFIER ::= { mldMIB 2 } mldMIBCompliances OBJECT IDENTIFIER ::= { mldMIBConformance 1 } mldMIBGroups OBJECT IDENTIFIER ::= { mldMIBConformance 2 } -- compliance statements mldHostMIBCompliance MODULE-COMPLIANCE STATUS current DESCRIPTION "The compliance statement for hosts running MLD and implementing the MLD MIB."
