This attribute is not applicable and is not displayed on CQC-based
ATM cards.
This attribute counts frames received from the ATM interface which
have been discarded. This count includes the count of
rxFrameDiscardClp and aal5RxErrors. It is independent of the
rxCellDiscard attribute.
This count includes frames discarded due to an AAL5 frame
reassembly error, frames discarded due to early packet discard
(EPD), and frames discarded due to processor (CPU) congestion.
This attribute is applicable only for connections that reassemble
incoming cells into frames. Connections which reassemble cells
into frames have a connectionPointType of connectionEndPoint.
AAL1 connections are an exception to this rule; even though they
have a connectionPointType of connectionEndPoint, they do not
do adaptation at this point.
The counter is reset to zero when the component is activated, or
when any critical attribute of the component is changed. The
counter wraps to zero when it exceeds its maximum value of
(2**64)-1.
