What is cienaCesPmIGMPTotalStatsBinIgmpnumQueryDiscardsPortDown?
This counter records IGMP queries that arrived tagged to a logical port the switch currently considers down, so it discards them rather than forwarding or processing them. A nonzero count here on an element that is supposed to be actively serving multicast traffic is a direct symptom of a link or port-state problem coinciding with active querier traffic, not a multicast-protocol issue in itself. For example, this counter beginning to increment right after a fiber cut takes down an uplink confirms the switch is still receiving querier traffic destined for a port that's no longer up.
