cmFlowPointHistoryFBCD
Module: CM-PERFORMANCE-MIB
OID (symbolic): CM-PERFORMANCE-MIB::cmFlowPointHistoryFBCD
OID (numeric): 1.3.6.1.4.1.2544.1.12.5.1.26.1.22
Node type: OBJECT-TYPE
Type: PerfCounter64
Access: read-only
Description: The number of Frame with Destination MAC BroadCast dropped in ingress FP.
What is cmFlowPointHistoryFBCD?
This read-only PerfCounter64 counts frames addressed to the broadcast MAC that were dropped on ingress at this flow point during the history bin. It helps an administrator spot broadcast storms or overly aggressive broadcast rate-limiting on the ingress side of the flow point, since legitimate ARP or DHCP broadcasts should rarely be dropped in normal operation. For instance, if end users on a VLAN report intermittent ARP failures, comparing spikes in cmFlowPointHistoryFBCD against the time of the complaint can confirm broadcast frames were being discarded rather than lost elsewhere.
