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 trkDiscardUnforward?
This 64-bit counter tracks packets received from the remote module (excluding the interrupting queue) that had to be discarded, most often because the remote protocol stack is incompatible or the packet couldn't be forwarded due to a recent connectivity loss or congestion. An admin watches this counter climb as a sign the trunk is dropping user traffic and needs investigation into protocol compatibility or downstream congestion.
