| IfIndex |
| The ifIndex value of the interface for which IGMP is operating. Range: 1 to 2147483647 |
| QueryInterval |
| The frequency at which IGMP Host-Query packets are transmitted on this interface. |
| Version |
| The version of IGMP which is running on this interface. |
| Querier |
| The address of the IGMP Querier on the IP subnet to which this interface is attached. |
| QueryMaxResponseTime |
| The maximum query response time advertised in IGMPv2 queries on this interface. Range: 0 to 255 |
| QuerierUpTime |
| The time since igmpInterfaceOperQuerier was last changed. |
| QuerierExpiryTime |
| The time when the Other Querier Present Timer expires. If the local system is the querier, the value of this object is zero. |
| Version1QuerierTimer |
| The time when 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. |
| WrongVersionQueries |
| The number of queries received whose IGMP version does not match igmpInterfaceOperVersion, 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. |
| Joins |
| 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. |
| ProxyIfIndex |
| Copied from related 'igmpInterfaceProxyIfIndex' entry (see description there). Range: 0 to 2147483647 |
| Groups |
| The current number of entries for this interface in the Cache Table. |
| Robustness |
| 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. Range: 1 to 255 |
| LastMembQueryIntvl |
| 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 igmpInterfaceOperVersion is 1. Range: 0 to 255 |
| Version2QuerierTimer |
| The time when the host assumes that there are no IGMPv2 routers present on the interface. While this is non- zero, the host will reply to all queries with version 1 or 2 membership reports. |
| GeneralQueryTimer |
| The time when the next general Query is issued on this interface. |
| StateLimit |
| The maximum allowed number of Reports/Queries per seconds on this interface. Must be greater zero to be active. |
| HostOnlyMode |
| An indication of whether the interface is running in host-only mode. If set to false this interface will operate in host and routing mode. Enumerations: |
| Fallback1ProxyIfIndex |
| Copied from related 'igmpInterfaceFallback1ProxyIfIndex' entry (see description there). Range: 0 to 2147483647 |
| Fallback2ProxyIfIndex |
| Copied from related 'igmpInterfaceFallback2ProxyIfIndex' entry (see description there). Range: 0 to 2147483647 |
| ChosenProxyIfIndex |
| Tells currently chosen 'upstream' interface (see further description in 'igmpInterfaceProxyIfIndex'). Range: 0 to 2147483647 |
| Fallback3ProxyIfIndex |
| Copied from related 'igmpInterfaceFallback3ProxyIfIndex' entry (see description there). Range: 0 to 2147483647 |
