What Is IGMP-STD-MIB?

IGMP-STD-MIB is a vendor-neutral IETF standards MIB (RFC 2933) for managing the Internet Group Management Protocol on router/multicast-capable interfaces. It exposes per-interface IGMP configuration (query interval, version, max response time) and operational status (querier presence, querier uptime/expiry, wrong-version query counts) along with a multicast group membership cache. It is used to monitor multicast networking software status — confirming which interface is the active IGMP querier, tracking querier uptime/expiry to detect querier failover, and catching wrong-version query counts that flag IGMP version mismatches between devices. As the canonical IGMP-STD-MIB reference (RFC 2933), this module standardizes how any compliant router exposes querier state and group-membership data regardless of vendor. As a standards MIB it typically works alongside PIM/multicast routing MIBs to give a complete multicast management picture. It is deployed on any IP router or Layer-3 switch that participates in IP multicast group management across enterprise and service-provider networks.

IPNetwork Monitor allows you to monitor SNMP objects defined in IGMP-STD-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

What Can Be Monitored

IGMP querier status and uptime
querier expiry timer
configured query interval
IGMP version per interface
wrong-version query count
multicast group membership cache

Supported Devices

vendor-neutral, standards-based MIB, not tied to a specific manufacturer — applies to any IP router or Layer-3 switch supporting multicast/IGMP

Monitoring Examples

An admin polls igmpInterfaceTable/igmpInterfaceEntry (by igmpInterfaceIfIndex) to check igmpInterfaceQuerier and igmpInterfaceQuerierUpTime, confirming which router is currently the elected IGMP querier and for how long, useful when diagnosing a querier failover event. igmpInterfaceWrongVersionQueries rising indicates a version mismatch (e.g., IGMPv2 vs v3) between neighboring devices, and igmpInterfaceQueryMaxResponseTime/igmpInterfaceQueryInterval confirm the configured timers match network design.

OIDs

OID symbolic	OID numeric	Type	Access	Description
igmpBaseMIBGroup	1.3.6.1.2.1.85.2.2.1			The basic collection of objects providing management of IGMP version 1 or 2.
IP igmpCacheAddress	1.3.6.1.2.1.85.1.2.1.1	IpAddress	not-accessible	The IP multicast group address for which this entry contains information.
igmpCacheEntry	1.3.6.1.2.1.85.1.2.1		not-accessible	An entry (conceptual row) in the igmpCacheTable.
TIK igmpCacheExpiryTime	1.3.6.1.2.1.85.1.2.1.6	TimeTicks	read-only	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.
NUM igmpCacheIfIndex	1.3.6.1.2.1.85.1.2.1.2	InterfaceIndex	not-accessible	The interface for which this entry contains information for an IP multicast group address.
IP igmpCacheLastReporter	1.3.6.1.2.1.85.1.2.1.4	IpAddress	read-only	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.
T/F igmpCacheSelf	1.3.6.1.2.1.85.1.2.1.3	TruthValue	read-create	An indication of whether the local system is a member of this group address on this interface.
ROW igmpCacheStatus	1.3.6.1.2.1.85.1.2.1.7	RowStatus	read-create	The status of this entry.
igmpCacheTable	1.3.6.1.2.1.85.1.2		not-accessible	The (conceptual) table listing the IP multicast groups for which there are members on a particular interface.
TIK igmpCacheUpTime	1.3.6.1.2.1.85.1.2.1.5	TimeTicks	read-only	The time elapsed since this entry was created.
TIK igmpCacheVersion1HostTimer	1.3.6.1.2.1.85.1.2.1.8	TimeTicks	read-only	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.
igmpHostOptMIBGroup	1.3.6.1.2.1.85.2.2.4			A collection of optional objects for IGMP hosts. Supporting this group can be especially useful in an environment with a router which does not support the IGMP MIB.
igmpInterfaceEntry	1.3.6.1.2.1.85.1.1.1		not-accessible	An entry (conceptual row) representing an interface on which IGMP is enabled.
G32 igmpInterfaceGroups	1.3.6.1.2.1.85.1.1.1.13	Gauge32	read-only	The current number of entries for this interface in the Cache Table.
NUM igmpInterfaceIfIndex	1.3.6.1.2.1.85.1.1.1.1	InterfaceIndex	not-accessible	The ifIndex value of the interface for which IGMP is enabled.
C32 igmpInterfaceJoins	1.3.6.1.2.1.85.1.1.1.11	Counter32	read-only	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.
U32 igmpInterfaceLastMembQueryIntvl	1.3.6.1.2.1.85.1.1.1.15	Unsigned32	read-create	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.
NUM igmpInterfaceProxyIfIndex	1.3.6.1.2.1.85.1.1.1.12	InterfaceIndexOrZero	read-create	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.
IP igmpInterfaceQuerier	1.3.6.1.2.1.85.1.1.1.5	IpAddress	read-only	The address of the IGMP Querier on the IP subnet to which this interface is attached.
TIK igmpInterfaceQuerierExpiryTime	1.3.6.1.2.1.85.1.1.1.8	TimeTicks	read-only	The amount of time remaining before the Other Querier Present Timer expires. If the local system is the querier, the value of this object is zero.
TIK igmpInterfaceQuerierUpTime	1.3.6.1.2.1.85.1.1.1.7	TimeTicks	read-only	The time since igmpInterfaceQuerier was last changed.
U32 igmpInterfaceQueryInterval	1.3.6.1.2.1.85.1.1.1.2	Unsigned32	read-create	The frequency at which IGMP Host-Query packets are transmitted on this interface.
U32 igmpInterfaceQueryMaxResponseTime	1.3.6.1.2.1.85.1.1.1.6	Unsigned32	read-create	The maximum query response time advertised in IGMPv2 queries on this interface.
U32 igmpInterfaceRobustness	1.3.6.1.2.1.85.1.1.1.14	Unsigned32	read-create	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.
ROW igmpInterfaceStatus	1.3.6.1.2.1.85.1.1.1.3	RowStatus	read-create	The activation of a row enables IGMP on the interface. The destruction of a row disables IGMP on the interface.
igmpInterfaceTable	1.3.6.1.2.1.85.1.1		not-accessible	The (conceptual) table listing the interfaces on which IGMP is enabled.
U32 igmpInterfaceVersion	1.3.6.1.2.1.85.1.1.1.4	Unsigned32	read-create	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.
TIK igmpInterfaceVersion1QuerierTimer	1.3.6.1.2.1.85.1.1.1.9	TimeTicks	read-only	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.
C32 igmpInterfaceWrongVersionQueries	1.3.6.1.2.1.85.1.1.1.10	Counter32	read-only	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.
