Description: Counter of L3 control protocol frames dropped due to packet fragmentation.
What is cmEthernetTrafficPortHistoryDroppedFragmented?
This counter records the number of Layer 3 control protocol frames dropped on this port during the archived historical interval because the packet was fragmented. A historical nonzero value helps the admin confirm that a past intermittent control-plane session issue was caused by fragmented packets being rejected on this port. For example, if a management session over this port failed intermittently last week, the admin would check cmEthernetTrafficPortHistoryDroppedFragmented from that period to see whether fragmentation drops correlate with the failures.
