DEFVAL { 125 } ::= { igmpInterfaceEntry 2 } igmpInterfaceStatus OBJECT-TYPE SYNTAX RowStatus MAX-ACCESS read-create STATUS current 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 } igmpInterfaceQuerier OBJECT-TYPE SYNTAX IpAddress MAX-ACCESS read-only STATUS current 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 STATUS current DESCRIPTION "The maximum query response time advertised in IGMPv2 queries on this interface."

If the local system is the querier, the value of this object is zero." ::= { igmpInterfaceEntry 8 } 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."

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."

DEFVAL { true } ::= { igmpCacheEntry 3 } 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." ::= { igmpCacheEntry 8 } -- conformance information igmpMIBConformance OBJECT IDENTIFIER ::= { igmpStdMIB 2 } igmpMIBCompliances OBJECT IDENTIFIER ::= { igmpMIBConformance 1 } igmpMIBGroups OBJECT IDENTIFIER ::= { igmpMIBConformance 2 } -- compliance statements igmpV1HostMIBCompliance MODULE-COMPLIANCE STATUS current DESCRIPTION "The compliance statement for hosts running IGMPv1 and implementing the IGMP MIB."
