1];Type=ETHERNETCSMACD;InputPacketRate=46529.74

PPS;MinimumDiscardRate=100.0;DuplexMode=FULLDUPLEX;OutputPacketRate=0.0

PPS;DiscardThreshold=5;InputPacketDiscardPct=5.049391

%;InputPacketDiscardRate=2349.4683

Re: NAM error

What is the current utilization for this port? Assuming an average packet size of 100 bytes (optimistically low), you're pulling 37,223,792 Mbps with a discard rate of just over 5%.

If you're experiencing problems with the data being collected in the NAM, then you might consider backing off the span data. If, however, the NAM's data looks okay, increase the discard threshold in DFM. A 10% threshold should prevent the alerts while still giving you a safe enough ceiling to spot potentially serious problems.
