| IfIndex |
| The ifIndex value of the interface for which IGMP is enabled. Range: 1 to 2147483647 |
| QueryInterval |
| The frequency at which IGMP Host-Query packets are transmitted on this interface. |
| Status |
| The activation of a row enables IGMP on the interface. The destruction of a row disables IGMP on the interface. Enumerations: - active (1)
- notInService (2)
- notReady (3)
- createAndGo (4)
- createAndWait (5)
- destroy (6)
|
| 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 (in tenths of seconds) advertised in IGMPv2 queries on this interface. Range: 0 to 255 |
| QuerierUpTime |
| The time since igmpInterfaceQuerier 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 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. |
| 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 |
| If not 0, specifies related 'upstream' interface for proxy-forwarding (see RFC-4605). In this case, all memberships learned on 'downstream' interface (represented by this row) are reported on upstream, and all related multicast-traffic is forwarded from upstream to downstream, from downstream to upstream (and from downstream to downstream, if further downstream interfaces refer to same upstream interface). For case that upstream interface is not usable (no related entries in MIB-table 'ipAddr'), 'fallback' interfaces can be specified via 'igmpInterfaceFallback(1/2/3)ProxyIfIndex', to be used instead for all reporting and forwarding. Currently chosen 'upstream' interface is told by 'igmpInterfaceOperChosenProxyIfIndex'. 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 (in tenths of seconds) 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. 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 |
| If not 0, specifies '1st fallback' for 'igmpInterfaceProxyIfIndex' (see further description there). Range: 0 to 2147483647 |
| Fallback2ProxyIfIndex |
| If not 0, specifies '2nd fallback' for 'igmpInterfaceProxyIfIndex' (see further description there). Range: 0 to 2147483647 |
| Fallback3ProxyIfIndex |
| If not 0, specifies '3rd fallback' for 'igmpInterfaceProxyIfIndex' (see further description there). Range: 0 to 2147483647 |
