This OID holds the Cell Delay Variation (CDV) tolerance for transmit traffic, specifying how much timing jitter is acceptable between cells. Network engineers set this based on the application's sensitivity to clock variation; tighter tolerances (lower values) are needed for real-time services like video. For example, a value of 8 means cells can arrive up to 8 microseconds earlier or later than perfectly evenly spaced without triggering a policing action.
