This read-write TruthValue lets an administrator override the IGMP/MLD query-related timer values, like query interval or max response time, on this VLAN instead of using the values learned from an upstream router's queries. An administrator enables this when they need the switch's own configured timers to take precedence over whatever an external querier advertises. For example, enabling rlIgmpMldSnoopVlanQueryOverride ensures the switch enforces its own admin-configured query interval rather than adopting a longer interval advertised by an external router.
