cmFlowPointHistoryFMCD
Module: CM-PERFORMANCE-MIB
OID (symbolic): CM-PERFORMANCE-MIB::cmFlowPointHistoryFMCD
OID (numeric): 1.3.6.1.4.1.2544.1.12.5.1.26.1.21
Node type: OBJECT-TYPE
Type: PerfCounter64
Access: read-only
Description: The number of Frame with Destination MAC MultiCast dropped in ingress FP.
What is cmFlowPointHistoryFMCD?
This read-only PerfCounter64 counts frames addressed to a multicast destination MAC that were dropped on ingress at this Ethernet flow point. It flags multicast traffic the flow point could not admit inward, which matters because a rising count can point to misconfigured multicast filtering, a full ingress queue, or an over-subscribed multicast group feeding this flow point. For example, a technician troubleshooting missing IPTV channels on one flow point would check whether cmFlowPointHistoryFMCD climbed during the outage window before suspecting a switch-side multicast join problem.
