This read-only Counter64 counts queries discarded specifically because they arrived before the minimum allowed interval since the previous query. This typically flags a misconfigured or rogue second querier flooding queries faster than the IGMP query interval allows — a cause the general QueryDiscards counter on this instance would not distinguish; because it is drawn from this instance's running statistics bin, it behaves like a long-running total rather than a rotating window, so admins baseline against it instead of expecting it to reset daily. On a metro aggregation uplink carrying several video EVCs, a count of 1,635 over the current statistics window is the kind of number an admin would trend against the join/leave rate on the same port to judge whether it's normal channel-surfing or an anomaly worth a closer look.
