OBJECT-TYPE
1.2.826.42.1.1578918.5.86.1.1.3.1.20
Description
The desired value of Last Member Query Interval on this interface. The Last Member Query Interval is the Max Response Time inserted into Group-Specific and Group-and-Source-specific Queries sent in response to Leave messages, and is also the amount of time between successive 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 mgmdRouterInterfaceVersion is 1. The value of this object is also irrelevant if this interface is configured to use immediate-leave behavior without a last member query - that is, if mgmdRouterInterfaceImmedtLeave is 'true' and mgmdRouterInterfaceQryBefImmdLv is 'false'. Different versions of IGMP and MLD support different maximum values in protocol messages. Accordingly, while 83876 is the absolute maximum, the allowed range may be smaller, depending on the configured protocol and version for this interface. MLDv2 supports values up to 83876 (10ths of seconds). MLDv1 supports values up to 655 (10ths of seconds). IGMPv3 supports values up to 31744 (10ths of seconds). IGMPv2 supports values up to 255 (10ths of seconds). IGMPv1 does not support specific queries. This interval is stored with the same exponential encoding format used for protocol packets. Values above 327 will be rounded down to the next lower value that can be expressed by MLDv2. For IGMPv3/MLDv2, if the entity is not performing IGMP snooping, this configured value will not be used if the local router is not the querier on this interface. The in-use value can be read from mgmdRouterInterfaceQrLstQryIvl.
