Access: read-only

Description: This attribute counts the number of packets received from the remote module that have been discarded. It does not include the packets received from the interrupting queue that have been discarded. This counter wraps around to zero when the maximum value is exceeded. Two main reasons that cause this counter to increase are: (1) the remote protocol is not compatible with the local protocol stack or, (2) the packet cannot be forwarded due to a recent loss of connectivity or due to congestion.

What is mscTrkDiscardUnforward?

A count of packets received from the remote module that had to be discarded, excluding the interrupting queue; it wraps to zero at its maximum. The two main causes are an incompatible remote protocol stack or a recent loss of connectivity/congestion, so a climbing count is worth correlating with mscTrkStagingAttempts.
