rlmgmdRouterInterfaceQrLastMembQueryIntvl
Module: CISCOSB-MGMD-ROUTER-MIB
OID (symbolic): CISCOSB-MGMD-ROUTER-MIB::rlmgmdRouterInterfaceQrLastMembQueryIntvl
OID (numeric): 1.3.6.1.4.1.9.6.1.101.225.1.1.13
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: The value of Last Member Query Interval in use 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'.
For IGMPv3/MLDv2, this may differ from the value configured using mgmdRouterInterfaceLastMembQueryIntvl if the local router is not the querier on this interface.
What is rlmgmdRouterInterfaceQrLastMembQueryIntvl?
This read-only Unsigned32 reports the Last Member Query Interval in effect on this interface, the response time inserted into Group-Specific and Source-Specific queries sent after Leave messages, which can be tuned to reduce leave latency at the cost of more query traffic. It shows the admin how quickly the router will confirm a group has no remaining members. For example, an admin troubleshooting slow multicast stream teardown after a host leaves would check this value to see if a long interval is delaying leave confirmation.
