Bytes Tail Dropped.
What is cmTrafficPortQosShaperHistoryBTD?
This counter tracks the total number of bytes that have been tail-dropped (discarded due to queue overflow) from a port's QoS traffic shaper during a historical measurement interval. Tail-drop indicates that the shaper's queue became full and newer arriving packets were dropped. Operators examine this metric to identify congestion patterns and tune QoS shaper parameters to minimize packet loss.
