Node type: OBJECT-TYPE
Type: PerfCounter64
Access: read-only
Description: Minimum bits transmitted on a port in any 1-sec with the PM interval
What is cmEthernetTrafficPortStatsIBRMinTx?
This counter records the lowest instantaneous transmit bit rate measured in any single second during the current performance-monitoring interval on this port. A near-zero minimum on an otherwise busy port can flag momentary transmission stalls to the admin, worth investigating if they recur. For example, if cmEthernetTrafficPortStatsIBRMinTx repeatedly bottoms out to zero during peak hours, the admin would suspect brief buffer starvation or a queuing issue on that port.
