Description: This attribute counts valid cells received from the ATM interface. This count includes cells which may be subsequently discarded. The counter is reset to zero when the component is activated, or when any critical attribute of the component is changed. On ATM IP FPs valid cells include cells that arrive on a VCC whose VPI.VCI cannot be identified. These cells are also counted under the droppedRxCell attribute. The value of this attribute on ATM IP FPs should be greater than or equal to the sum of droppedRxCell and all the Vcc and Vpc rxCell attributes under this interface. The counter wraps to zero when it exceeds its maximum value of (2**64)-1.
